Résumé : Objective: The aim of this study was to clarify the epidemiology of laboratory-confirmed influenza in Hanoi,
Vietnam. Methods: Influenza was detected by virus isolation from nasopharyngeal swabs of influenzalike-illness (ILI)
patients who reported to outpatient clinics in Hanoi, Vietnam between 2001 and 2003, before the start of avian
influenza A/H5N1 outbreaks. Influenza isolates were characterized by hemagglutinin inhibition test. Results: A total of
4708 nasopharyngeal swabs were collected from patients with ILI. Influenza was positive in 119 (2.5%) samples by
virus isolation. Influenza circulated throughout the year, with possible two peaks in summer and winter. Influenza B
viruses and A/H3N2 predominated in 2001 and 2002, respectively, and mixed circulation ofA/H1N1, A/H3N2 and B
were observed in 2003. The seasonality of influenza roughly matched with clinical case reports in the North Region by
National Communicable Disease Surveillance in Vietnam. Conclusions: The findings of year-round and biannual peak
circulation of influenza in a subtropical area were in accordance with the results of previous studies in tropical and
subtropical regions. Our observations indicated that establishment of laboratory-based surveillance in tropical and
sub-tropical countries is important for taking actions for pandemic strategies, and links to the WHO global influenza
network.

Résumé : In the context of influenza pandemic preparedness planning, a surveillance system for influenza and other
acute respiratory illnesses was implemented in Lower Saxony at the beginning of the influenza season 2004/2005 and
coordinated by the Governmental Institute of Public Health of Lower Saxony. This surveillance system represents an
addition to already existing national monitoring systems. The goal of this surveillance system is to have available
prompt information on the beginning, course and end of the influenza season and to recognise the spectrum of
pathogens and identify outbreaks of other viral acute respiratory illnesses (ARI). For this purpose an all-season
surveillance was established consisting of two supplementary modules. The first module is a symptom-oriented
surveillance of acute respiratory illnesses in children of pre-school day care facilities. In the second module a
virological surveillance in cooperation with selected medical practices was established. While the temporal course and
burden of ARI in all Lower Saxony can be assessed by the surveillance of children in the day-care facilities in a
sensitive, but less specific way, the virological surveillance provides highly specific information on the prevailing
pathogens in ARI patients at a certain time. This information, in return, gives an indication about the responsible
pathogens causing ARI in children of the day-care facilities. The first experience with these two complementary
surveillance modules shows that in Lower Saxony a well accepted, prompt and meaningful monitoring system is
available for the recognition and description of the occurrence of ARI and concomitantly of influenza. An extension of
this surveillance to other pathogens or disease scenarios is possible.

Résumé : Influenza vaccination rates are generally low among healthcare workers (HCWs) worldwide. In September
2005, the Hellenic Center for Disease Control and Prevention conducted a nationwide campaign to promote influenza
vaccination in hospital HCWs. During the 2005-2006 influenza season, the overall vaccination rate among HCWs was
16.36% (range: 0-85.96%). The self-reported vaccination rate during the previous season was 1.72%, indicating a
9.5-fold increase. Compared with physicians, significantly fewer technical personnel were vaccinated, whereas
administrative personnel were more likely to receive the vaccine. Among clinicians, rates for internal medicine
departments exceeded those of surgical departments by a factor of 2.71 and laboratory medicine departments by a factor
of 2.36. Multivariate analysis showed lower vaccination rates in large hospitals (>200 beds) than in smaller hospitals
and lower rates in hospitals with specialist services (intensive care unit, psychiatry or dermatology) than in general
hospitals. Factors associated with higher rates included working in northern Greece, in a paediatric or an oncology
hospital, or in a prefecture with avian influenza H5N1 activity. In conclusion, in Greece influenza vaccination rates
among HCWs remain low, but the implementation of a nationwide campaign had a considerable impact. Efforts should
focus on hospital- and HCW-associated factors to increase vaccination uptake.

Résumé : This short-term observational study of infection control practice was performed in the medical emergency
outpatient department (EMOPD) of a tertiary-care hospital in India when threatened by an outbreak of severe acute
respiratory syndrome (SARS). An investigator attended the lobby daily to screen patients with symptoms for SARS.
Patient/attendant load, patient flow, medical staff working practices and position in the EMOPD were observed.
Infection control measures such as fumigation and cleaning were noted, as was the EMOPD laboratory function, use of
personnel protection and display of information on infectious diseases. A total of 162 (7.4%) of the 2165 patients
surveyed had respiratory symptoms but no cases of SARS were found. The flow of patients and their attendants was not
systematic. No laboratory tests for SARS were available, and no educational material on SARS was displayed. The
EMOPDs in key hospitals need be able to screen for infectious diseases, especially in view of the threats from SARS
and Avian influenza.

Résumé : Background: The rapid diagnosis of influenza can alter the management of a patient's illness, resulting in
reduced antibiotic usage, correct use of influenza antivirals and reduced length of stay in hospital emergency
departments. The rapid tests have also been used to detect outbreaks in institutions and may play a role in pandemic
influenza control. Objectives: To test six different rapid influenza tests, in a head-to-head comparison for the detection
of seasonal influenza types A and B, compared to laboratory-based tests. Study design: One hundred and seventy-seven
clinical specimens taken from mostly paediatric patients between June and October 2006 were tested using six influenza
diagnostic tests and three laboratory-based techniques (immunofluorescence, cell culture and real-time RT-PCR).
Results and conclusion: Compared with cell culture, five of the rapid tests (Binax Now Influenza A&B, Directigen EZ
Flu A + B, Denka Seiken Quick Ex-Flu, Fujirebio Espline Influenza A&B-N, and Quidel Quick Vue Influenza A + B
Test) demonstrated a similar influenza A sensitivity of between 67-71% and a specificity of 99-100%, however one
rapid test (Rockeby Influenza A Antigen Test) had a significantly lower influenza A sensitivity of only 10% (specificity
was 100%). For the five kits that detected influenza B antigen, sensitivity was considerably lower than that seen for
influenza A (sensitivity for all the kits was 30%), although the number of specimens containing influenza B viruses was
low.

Résumé : BACKGROUND: Influenza causes episodic pandemics when viral antigens shift in ways that elude herd
immunity. Avian influenza A H5N1, currently epizootic in bird populations in Asia and Europe, appears to have
pandemic potential. STUDY DESIGN AND METHODS: The virology of influenza, the history of the 1918 pandemic,
and the structure of the health care and the blood transfusion systems are briefly reviewed. Morbidity and mortality
experience from the 1918 pandemic are projected onto the current health care structure to predict points of failure that
are likely in a modern pandemic. RESULTS: Blood donor centers are likely to experience loss of donors, workers, and
reliable transport of specimens to national testing laboratories and degradation of response times from national testing
labs. Transfusion services are likely to experience critical losses of workers and of reagent red cells (RBCs) that will
make their automated procedures unworkable. Loss of medical directors, supervisors, and lead technicians may make
alternative procedures unworkable as well. CONCLUSIONS: Lower blood collection capacity and transfusion service
support capability will reduce the availability of RBCs and especially of platelets. Plans for rationing medical care need
to take the vulnerability of the blood transfusion system into account.

Résumé : Since 2003, the number of human cases of infections with highly pathogenic avian influenza viruses of the
H5N1 subtype is still increasing, and, therefore, the development of safe and effective vaccines is considered a priority.
However, the global production capacity of conventional vaccines is limited and insufficient for a worldwide
vaccination campaign. In the present study, an alternative H5N1 vaccine candidate based on the replication-deficient
modified vaccinia virus Ankara (MVA) was evaluated. C57BL/6J mice were immunized twice with MVA expressing
the hemagglutinin (HA) gene from influenza virus A/Hongkong/156/97 (MVA-HA-HK/97) or A/Vietnam/1194/04
(MVA-HA-VN/04). Subsequently, recombinant MVA-induced protective immunity was assessed after challenge
infection with 3 antigenically distinct strains of H5N1 influenza viruses: A/Hongkong/156/97, A/Vietnam/1194/04, and
A/Indonesia/5/05. Our data suggest that recombinant MVA expressing the HA of influenza virus A/Vietnam/1194/04 is
a promising alternative vaccine candidate that could be used for the induction of protective immunity against various
H5N1 influenza strains.

Résumé : This paper considers the impact of the new Indian patent regime on the important issue of access to
affordable drugs. Access is dependent, in part, on the ability of generic manufacturers to produce cheap generic drugs.
Working with the bird flu patent example, this paper will demonstrate that far from abetting 'genericide', the new regime
provides adequate legal windows to aid the continued production of affordable generics. However, the mere existence
of such windows/flexibilities is not enough - generic manufacturers will only exploit such windows when it is
economically and politically viable to do so.

Résumé : Background: The clinical management of H5N1 influenza virus infection in humans remains unclear.
Combination chemotherapy with drugs that target different viral proteins might be more effective than monotherapy.
Methods: BALB/c mice were treated by oral gavage for 5 days with amantadine (1.5, 15 or 30 mg/kg/day) and
oseltamivir (1 or 10 mg/kg/day) separately or in combination. Mice were challenged 24 h after initiation of treatment
with 10 mouse 50% lethal doses of either amantadine-sensitive (having S31 in the M2 protein) or amantadine-resistant
(having N31 in the M2 protein) recombinant A/Vietnam/1203/04 (H5N1) virus. Results: Combination treatment with
amantadine (15 or 30 mg/kg/day) and oseltamivir (10 mg/kg/day) provided greater protection (60% and 90%,
respectively) against lethal infection with amantadine-sensitive H5N1 virus than did monotherapy. Moreover, spread of
the virus to the brain was prevented by both combination regimens. The efficacy of the drug combinations against
amantadine-resistant H5N1 virus was comparable to that of oseltamivir alone. Oseltamivir produced a dose-dependent
effect against both recombinant H5N1 viruses (P<0.05) but did not provide complete protection against lethal infection.
Importantly, no mutations in the HA, NA and M2 proteins were detected when the two drugs were used in combination.
Conclusions: Combination chemotherapy provided a survival advantage over single-agent treatment of mice inoculated
with neurotropic H5N1 influenza virus. This strategy might be an option for the control of pandemic influenza viruses
that are sensitive to amantadine. Combinations that include other drugs should be explored.

Résumé : The development of safe and effective vaccines for avian influenza viruses is a priority for pandemic
preparedness. Adjuvants improve the efficacy of vaccines and may allow antigen sparing during a pandemic. We have
previously shown that influenza virus-like particles (VLPs) comprised of HA, NA, and Ml proteins represent a
candidate vaccine for avian influenza H9N2 virus Pushko P, Tumpey TM, Fang Bu, Knell J, Robinson R, Smith G.
Influenza virus-like particles comprised of the HA, NA, and Ml proteins of H9N2 influenza virus induce protective
immune responses in BALB/c mice. Vaccine 2005;23(50):5751-9. In this study, an H9N2 VLP vaccine and
recombinant HA (rH9) vaccine were evaluated in three animal models. The H9N2 VLP vaccine protected mice and
ferrets from challenge with A/Hong Kong/1073/99 (H9N2) virus. Novasome adjuvant improved immunogenicity and
protection. Positive effect of the adjuvant was also detected using the rH9 vaccine. The results have implications for the
development of safe and effective vaccines for avian influenza viruses with pandemic potential.

Résumé : A yield enhancement technology for use in influenza vaccine manufacturing has been developed to maximize
the recovery of influenza virus from allantoic fluid of virus-infected chick embryos; the standard raw material for
influenza vaccine. Virus associated with amorphous debris in the allantoic fluid can be dissociated from the debris and
recovered, thereby increasing viral yield. Dissociation can be achieved by subjecting the virus-debris complex to
conditions of increased ionic strength at defined pH. Multifold increases in viral yield per ml of allantoic fluid were
observed. The degree of yield enhancement is strain-specific, however, increases were observed in all type A and type
B influenza strains tested. The heightened influenza virus recoveries can facilitate rapid vaccine manufacture, with
increased numbers of doses produced, and may become essential at a time of influenza pandemic.

Résumé : Recent research has demonstrated that swine and poultry professionals, especially those who work in large
confinement facilities, are at markedly increased risk of zoonotic influenza virus infections. In serving as a bridging
population for influenza virus spread between animals and man, these workers may introduce zoonotic influenza virus
into their homes and communities as well as expose domestic swine and poultry to human influenza viruses. Prolonged
and intense occupational exposures of humans working in swine or poultry confinement buildings could facilitate the
generation of novel influenza viruses, as well as accelerate human influenza epidemics. Because of their potential
bridging role, we posit that such workers should be recognized as a priority target group for annual influenza vaccines
and receive special training to reduce the risk of influenza transmission. They should also be considered for increased
surveillance and priority receipt of pandemic vaccines and antivirals.

Résumé : Five hundred and forty birds in three zoos were vaccinated twice against avian influenza with a 6-week
interval using an inactivated H5N9 vaccine. Serological response was evaluated by hemagglutination inhibition test 4-6
weeks following the second vaccine administration. 84% of the birds seroconverted, and 76% developed a titre >=32.
The geometric mean titre after vaccination was 137. A significant species variation in response was noted; penguins,
pelicans, ducks, geese, herons, Guinea fowl, cranes, cockatiels, lovebirds, and barbets showed very poor response to
vaccination, while very high titres and seroconversion rates were seen in flamingos, ibis, rheas, Congo peafowl,
black-winged stilts, amazon parrots, and kookaburras.

Résumé : <Mathematical point>To minimise the health impact of pandemic influenza, general practice will need to
provide influenza-related and non-influenza primary health care, as well as contribute to the public health goal of
disease control. <Mathematical point>Through interviews and workshops with general practitioners, nurses and policy
leaders between March and July 2006, and literature analysis, we identified potential models of general practice in an
established pandemic, and assessed their strengths and weaknesses. <Mathematical point>Three possible clinical
models were identified: a default model of no change to service delivery; a streamed services model, where general
practices reorganise themselves to take on either influenza-specific care or other clinical services; and a
staff-determined mixed model, where staff move between different types of services. <Mathematical point>No single
model or set of strategies meets the needs of all general practices to deliver and sustain the essential functions of
primary health care during an established pandemic. Governments, general practice and the relevant peak professional
bodies should decide before a pandemic on the suite of measures needed to support the models most suitable in their
regions. <Mathematical point>Effective participation by general practice in a pandemic requires supplementary
infrastructure support, changes to financial and staffing patterns, a review of legislation on medicolegal implications
during an emergency, and intensive collaboration between general practices.

Résumé : Les maladies infectieuses representent un probleme de sante majeur, tant pour les pays developpes, que pour
les pays emergents. Envisagees a l' echelon mondial, les maladies infectieuses sont, en effet, a l' origine d' environ un
tiers de tous les deces (46 % des causes de morts dans les pays en voie de developpement). D' importants appels ont ete
lances travers le monde dans le but d' ameliorer les systemes de sante publique, compte tenu des dangers croissants que
presentent les maladies infectieuses, du fait d' un ensemble de microbes d' apparition recente ou resurgents, tels le
SRAS, la tuberculose, le sida, la legionellose, le microbe Ebola, l' encephalite du Nil, les infections nosocomiales
opportunistes, les nouvelles varietes de grippe. Ces facteurs sont egalement associes a des problemes de securite
microbiologiques des aliments et au role joue par le developpement des voyages internationaux, par la croissance du
commerce mondial de l' agriculture, tous elements qui s' integrent dans les mailles du bioterrorisme. Les maladies
infectieuses animales (aux consequences vitales) tels la grippe aviaire, le virus du singe, les maladies dues aux aliments,
transmissibles ou non a l' homme, les maladies vegetales, posent, elles aussi, des problemes, et representent autant de
cibles potentielles pour le bioterrorisme. Et, meme si nous disposons d' antibiotiques et de vaccins, les defis persistent
dans la lutte contre les micro-organismes, car l' on assiste a une augmentation des resistances antibacteriennes et
antivirales. Les strategies vaccinales, quant a elles, peuvent echouer du fait de leur cout trop eleve pour les pays en voie
de developpement, voire de l' opposition rencontree dans certains pays de l' Union Europeenne, sans sous-estimer les
variations antigeniques de certains micro-organismes, et de certains virus. L' Academie Allemande des Sciences
Leopoldina, en collaboration avec le Comite Consultatif de l' Academie Europeenne des Sciences, a precise quelles
devaient etre les actions a entreprendre pour lutter contre les maladies infectieuses, et identifie les zones les plus
exposees, autant de realites auxquelles les responsables politiques de l' union Europeenne devront faire face. Ces
priorites seront exposees et discutees.

Résumé : Highly water-soluble, artificial glycopolypeptides with a <gamma>-polyglutamic acid (y-PGA) backbone
derived from Bacillus subtilis sp. and multivalent sialyloligosaccharide units have been chemoenzymatically
synthesized
5-Trifluoroacetamidopentyl <beta>-N-acetyllactosaminide and 5-trifluoroacetamidopentyl <beta>-lactoside wereenzymatically synthesized from LacNAc and lactose, respectively, by cellulase-mediated condensation with5-trifluoroacetamido-l-pentanol. After deacetylation, the resulting 5-aminopentyl p-LacNAc and <beta>-lactosideglycosides were coupled to the <alpha>-carboxyl groups of the <gamma>-PGA side chains. The artificialglycopolypeptides carrying LacNAc and lactose were further converted to Neu5Aca2-(3/6)Gal<beta>1-Glc<beta> andNeu5Ac<alpha>2-(3/6)Ga1<beta>1-4GlcNAc<beta> <alpha>2,6-sialyltransferase, respectively. The interaction of these glycopolypeptides with various influenza virusstrains has been investigated by three different methods. Glycopolypeptides carrying Neu5Ac<alpha>2,6LacNAcinhibited hemagglutination mediated by influenza A and B viruses, and their relative binding affinities forhemagglutinin were 10<sup>2- to 10<sup>4-fold higher than that of the naturally occurring fetuin control. Aglycopolypeptide carrying Neu5Ac<alpha>2,6LacNAc inhibited infection by A/Memphis/1/71 (H3N2) 93 times morestrongly than fetuin, as assessed by cytopathic effects on virus-infected MDCK cells. The avian virus A/duck/Hongkong/4/78 (H5N3) bound strongly to Neu5Ac<alpha>2,3LacNAc/Lac-carrying glycopolypeptides, whereas the humanvirus A/Meniphis/1/71 (H3N2) bound to Neu5Ac<alpha>2,6LacNAc in preference to Neu5Ac<alpha>2,6Lac. Takentogether, these results indicate that the binding of viruses to terminal sialic acids is markedly affected by the structure ofthe asialo portion, in this case either LacNAc or lactose, in the sugar chain of glycopolypeptides.

Résumé : Entre fevrier et aout 2006, 490 oiseaux sauvages regroupes en 302 lots ont ete collectes dans le departement
de l' Ain et analyses au Laboratoire Departemental d' Analyses. L' analyse virologique par PCR des ecouvillons
tracheaux et cloacaux a revele la presence du gene M commun aux virus influenza aviaires de type A dans 41 lots dont
39 provenaient de la Dombes. Le Laboratoire National de Reference (AFSSA Ploufragan) a confirme la presence du
virus H5N1 hautement pathogene (HP). Des oiseaux malades presentaient cliniquement des signes nerveux. A l'
autopsie, les lesions congestivo-hemorragiques predominaient (cavite thoraco-abdominale, coeur et reins), souvent
associees, chez les cygnes tubercules, a des lesions d' emphyseme pulmonaire, de pancreatite et d' encephalite. Certains
oiseaux porteurs de lesions visibles a l' examen necropsique ou histologique avaient une PCR negative. Le virus,
probablement introduit par des fuligules milouins, a affecte surtout des cygnes mais aussi, d' autres oiseaux aquatiques
ou predateurs. La maladie est survenue entre fevrier et avril et est restee circonscrite a quelques communes; l' excretion
de virus H5N1 HP a ete mise en evidence chez un faible nombre d' oiseaux sauvages et a disparu avec la remontee de la

Résumé : The ongoing H5N1 epidemic is currently affecting a number of avian species, including waterfowl. These
birds appear to have an important role as reservoirs of infection and comprehensive data on the efficacy of vaccination
is currently lacking. The present paper reports the effect of a two dose vaccination programme with a conventional
inactivated product on infection, lateral spread, shedding and presence of virus in commodities such as meat and viscera
of Pekin ducks. Vaccination of this species appears to be efficacious in suppressing viral shedding, and preventing
viraemia and lateral spread of infection to unvaccinated and vaccinated Pekin ducks.

Résumé : A study was performed to investigate the reproducibility of haemagglutinin-inhibition (HI) and virus
neutralising (VN) assays for detection of anti-influenza antibody. Participants in 11 laboratories from eight countries
measured antibody to egg-grown A/Japan/434/2003, cell-grown A/Japan/434/2003 and A/Panama/2007/99 (H3N2)
viruses in 18 human and two post-infection ferret sera. There was significant intra-laboratory assay variability for VN
compared to HI. For replicate assays within laboratories, 14/410 (3%) and 130/631 (21%) titres differed by >2-fold (p <
0.0001), and 0/410 (0%) and 35/631 (6%) titres differed by >5-fold (p < 0.0001) by HI and VN, respectively. Although
both assays showed inter-laboratory variation, VN assays were significantly more variable than HI. Median geometric
coefficients of variation (GCV) forVN assays with each virus were 256%, 323% and 359% compared to 138%, 155%
and 261% with HI. A serum standard improved inter-laboratory agreement and reduced median GCVs. This study
raises concern about comparability of serology results from H5N1 vaccine trials and it is proposed that an International
Standard for influenza H5N 1 antibody is developed.

Résumé : Highly pathogenic avian influenza virus (H5N1) is an emerging pathogen with the potential to cause great
harm to humans, and there is concern about the potential for a new influenza pandemic. This virus is resistant to the
antiviral effects of interferons and tumor necrosis factor-<alpha>. However, the mechanism of interferon-independent
protective innate immunity is not well understood. The prophylactic effects of chitin microparticles as a stimulator of
innate mucosal immunity against a recently obtained strain of H5N1 influenza virus infection were examined in mice.
Clinical parameters and the survival rate of mice treated by intranasal application of chitin microparticles were
significantly improved compared to non-treated mice after a lethal influenza virus challenge. Flow cytometric analysis
revealed that the number of natural killer cells that expressed tumor necrosis factor-related apoptosis-inducing ligand
(TRAIL) and that had migrated into the cervical lymph node was markedly increased (26-fold) after intranasal
treatment with chitin microparticles. In addition, the level of IL-6 and interferon-gamma-inducible protein-10 (IP-10) in
the nasal mucosa after H5N1 influenza virus challenge was decreased by prophylactictreatmentwith chitin
microparticles. These results suggest that prophylactic intranasal administration of chitin microparticles enhanced the
local accumulation of natural killer cells and suppressed hyper-induction of cytokines, resulting in an innate immune
response to prevent pathogenesis of H5N1 influenza virus.

Résumé : Increasing diversity among influenza H5N1 viruses has resulted in the need for sensitive and specific
diagnostic assays, fully validated for the detection of H5 viruses belonging to all hemagglutinin (HA) clades,
particularly the recently circulating H5N1 viruses of clade 2. In this report, the development and validation of a
real-time, one-step TaqMan reverse transcription-PCR (RT-PCR) assay specific for the detection of influenza A H5
viruses from clades 1,1', 2, and 3 is described. The real-time assay for H5 virus was shown to be highly sensitive,
detecting H5 virus levels of <1 PFU from each of the HA clades. Specificity of the H5 RT-PCR for influenza A H5
viruses was demonstrated by using influenza A viruses of different subtypes, clinical samples containing influenza A
viruses H1N1, H3N2, and H5N1, influenza B viruses, and other respiratory viruses. The usefulness of the inclusion of a
distinguishable assay positive control and of confirmatory assays for the laboratory diagnosis and verification of H5
virus infections was demonstrated. A real-time RT-PCR pyrose-quencing assay, a restriction enzyme digestion assay,
and direct sequencing of the H5 real-time RT-PCR amplicon were validated for the confirmation of H5 detection by the
diagnostic real-time assay. The H5 real-time assay was applied to diagnostic testing for suspected cases of influenza A
virus H5 infection in the United Kingdom. Influenza A H5 viruses were not detected in the cases analyzed; however,
influenza A H3N2 virus was detected in 57% of the suspected cases of H5. The H5 TaqMan real-time RT-PCR and
confirmatory assays will be useful tools for the laboratory surveillance and rapid diagnosis of H5 infections in humans.

Résumé : Recent outbreaks of avian influenza are being caused by unusually virulent H5N1 strains. It is unknown what
makes these recent H5N1 strains more aggressive than previously circulating strains. Here, we have compared more
than 3000 RNA sequences of segment 8 of type A influenza viruses and found a unique single nucleotide substitution
typically associated with recent H5N1 strains. By phylogenetic analysis, biochemical and biophysical experiments, we
demonstrate that this substitution dramatically affects the equilibrium between a hairpin and a pseudoknot conformation
near the 3' splice-site of the NS gene. This conformational shift may have consequences for splicing regulation of
segment 8 mRNA. Our data suggest that besides changes at the protein level, changes in RNA secondary structure
should be seriously considered when attempting to explain influenza virus evolution.

Résumé : Background: Highly pathogenic avian influenza (HPAI) H5N1 has spread globally in birds and infected over
270 humans with an apparently high mortality rate. Serologic studies to determine the extent of asymptomatic H5N1
infection in humans and other mammals and to investigate the immunogenicity of current H5N1 vaccine candidates
have been hampered by the biosafety requirements needed for H5N1 microneutralization tests. Objective: Development
of a serodiagnostic tool for highly pathogenic influenza that reproduces H5N1 biology but can be used with less
biohazard. Study Design: We have generated and evaluated H5 hemagglutinin pseudotyped lentiviral particles encoding
the luciferase reporter (H5pp). Results: H5pp entry into target cells depends on a2-3 cell surface sialic acids and
requires low pH for membrane fusion. H5pp infectivity is specifically neutralized by sera from patients and animals
infected with H5N1 and correlates well with conventional microneutralization test. Conclusions: H5pp reproduce H5N1
influenza virus entry into target cells and potentially provides a high-throughput and safe method for
sero-epidemiology.

Résumé : Highly pathogenic avian influenza (HPAI) H5N1 virus infections have recently caused unprecedented
morbidity and mortality in a wide range of avian species. European Commission directive 2005/744/EC allowed
vaccination in zoos under strict conditions, while reducing confinement measures. Vaccination with a commercial
H5N2 vaccine with vaccine doses adapted to mean body weight per species was safe, and proved immunogenic
throughout the range of species tested, with some variations between and within taxonomic orders. After booster
vaccination the overall homologous geometric mean titre (GMT) to the vaccine strain, measured in 334 birds, was 190
(95% CI: 152-236), and 80.5% of vaccinated birds developed a titre of >=40. Titres to the HPAI H5N1 virus followed a
similar trend, but were lower (GMT: 61 (95% CI: 49-76); 61% >=40). The breadth of the immune response was further
demonstrated by measuring antibody titres against prototype strains of four antigenic clades of currently circulating
H5N1 viruses. These data indicate that vaccination should be regarded as a beneficial component of the preventive
measures (including increased bio-security and monitoring) that can be undertaken in zoos to prevent an outbreak of
and decrease environmental contamination by HPAI H5N1 virus, while alleviating confinement measures.

Résumé : Protection of chickens against avian influenza (AI) is mostly attributed to production of antibodies against the
viral glycoprotein hemagglutinin, whereas less is known about the protective role of antibodies to the other surface
glycoprotein neuraminidase (NA). Therefore, vaccines encoding NA antigen (e.g., DNA and alphavirus-based virus like
replicon particles (VRP)) or baculovirus-expressed recombinant NA (rN2) were tested for their ability to protect against
highly pathogenic AI (HPAI) in chickens. Vaccination with A/Pheasant/Maryland/4457/93 (Ph/MD) rN2 protein
produced significantly higher levels of NA-inhibition (NI) activity and 88% protection from HPAI H5N2 challenge than
vaccination with Ph/MD N2 DNA (25% protection). Vaccination with Ph/MD N2 VRP a minimum of two times also
produced high levels of NI activity and protection against HPAI challenge (63% protection). Vaccination with VRP
encoding an N2 gene that was genetically distant from the challenge virus N2 failed to protect chickens. Vaccines
producing higher levels of NI activity conferred partial protection, but failed to affect viral shedding. Consideration of
the homology between vaccine and challenge virus isolate NA genes may provide improved immunity if high levels of
NI activity are obtained.

Résumé : Highly pathogenic avian H5N1 influenza viruses are now widespread in poultry in Asia and have recently
spread to some African and European countries. Interspecies transmission of these viruses to humans poses a major
threat to public health. To better understand the basis of pathogenesis of H5N1 viruses, we have investigated the role of
proinflammatory cytokines in transgenic mice deficient in interleukin-6 (IL-6), macrophage inflammatory protein 1
alpha (MIP-la), IL-1 receptor (IL-1R), or tumor necrosis factor receptor 1 (TNFR1) by the use of two avian influenza A
viruses isolated from humans, A/Hong Kong/483/97 (HK/483) and A/Hong Kong/486/97 (HK/486), which exhibit high
and low lethality in mice, respectively. The course of disease and the extent of virus replication and spread in IL-6- and
MIP-1<alpha>-deficient mice were not different from those observed in wild-type mice during acute infection with
1,000 50% mouse infective doses of either H5N1 virus. However, with HK/486 virus, IL-1R-deficient mice exhibited
heightened morbidity and mortality due to infection, whereas no such differences were observed with the more virulent
HK/483 virus. Furthermore, TNFR1-deficient mice exhibited significantly reduced morbidity following challenge with
either H5N1 virus but no difference in viral replication and spread or ultimate disease outcome compared with
wild-type mice. These results suggest that TNF-<alpha> may contribute to morbidity during H5N1 influenza virus
infection, while IL-1 may be important for effective virus clearance in nonlethal H5N1 disease.

Résumé : H9N2 influenza viruses have become established and maintain long-term endemicity in terrestrial poultry in
Asian countries. Occasionally these viruses transmit to other mammals, including humans. Increasing epidemiological
and laboratory findings suggest that quail may be an important host, as they are susceptible to different subtypes of
influenza viruses. To better understand the role of quail in influenza virus ecology and evolution, H9N2 viruses isolated
from quail during 2000 to 2005 were antigenically and genetically characterized. Our results showed that H9N2 viruses
are prevalent year-round in southern China and replicate mainly asymptomatically in the respiratory tract of quail.
Genetic analysis revealed that both the G1-like and Ck/Bei-like H9N2 lineages were cocirculating in quail since 2000.
Phylogenetic analyses demonstrated that most of the isolates tested were double- or multiple-reassortant variants, with
four G1-like and 16 Ck/Bei-like genotypes recognized. A novel genotype of Gl-like virus became predominant in quail
since 2003, while multiple Ck/Bei-like genotypes were introduced into quail, wherein they incorporated G1-like gene
segments, but none of them became established in this host. Those Ck/Bei-like reassortants generated in quail have then
been introduced into other poultry. These complex interactions form a two-way transmission system between quail and
other types of poultry. The present study provides evidence that H9N2 and H5N1 subtype viruses have also exchanged
gene segments to generate currently circulating reassortants of both subtypes that have pandemic potential. Continuing
influenza virus surveillance in poultry is critical to understanding the genesis and emergence of potentially pandemic
strains in this region.

Résumé : T-705 (6-fluoro-3-hydroxy-2-pyrazinecarboxamide) was inhibitory to four strains of avian H5N1 influenza
virus in MDCK cells, with the 90% effective concentrations ranging from 1.3 to 7.7 <mu>M, as determined by a virus
yield reduction assay. The efficacy was less than that exerted by oseltamivir carboxylate or zanamivir but was greater
than that exerted by ribavirin. Experiments with mice lethally infected with influenza A/Duck/ MN/1525/81 (H5N1)
virus showed that T-705 administered per os once, twice, or four times daily for 5 days beginning 1 h after virus
exposure was highly inhibitory to the infection. Dosages from 30 to 300 mg/kg of body weight/day were well tolerated;
each prevented death, lessened the decline of arterial oxygen saturation (SaO<sub>2), and inhibited lung consolidation
and lung virus titers. Dosages from 30 to 300 mg/kg/day administered once or twice daily also significantly prevented
the death of the mice. Oseltamivir (20 mg/kg/day), administered per os twice daily for 5 days, was tested in parallel in
two experiments; it was only weakly effective against the infection. The four-times-daily T-705 treatments at 300
mg/kg/day could be delayed until 96 h after virus exposure and still significantly inhibit the infection. Single T-705
treatments administered up to 60 h after virus exposure also prevented death and the decline of SaO<sub>2.
Characterization of the pathogenesis of the duck influenza H5N1 virus used in these studies was undertaken; although
the virus was highly pathogenic to mice, it was less neurotropic than has been described for clinical isolates of the
H5N1 virus. These data indicate that T-705 may be useful for the treatment of avian influenza virus infections.

Résumé : The recent recurrence of highly pathogenic avian influenza virus A H5N1 was firstly reported in
mid-December 2003 and continued through 2005. This study describes a sensitive and specific real-time RT-PCR
method for the detection of influenza A subtype H5 and for monitoring virus loads. Using serial dilutions of influenza A
H5N1 cultures, this assay reproducibly determined the lowest detection limit to be approximately 5<multiplication
sign>10<sup>-<sup>2 50% egg infective doses (EID<sub>5<sub>0). In contrast, the minimum detection limit was
approximately 3 EID<sub>5<sub>0 in conventional RT-PCR with WHO primers and 10 EID<sub>5<sub>0 in
antigen-capture ELISA. In tests of serial dilutions of in vitro-transcribed influenza A H5 gene RNA, there was linear
amplification from 40 copies to 4<multiplication sign>10<sup>8 copies of target RNA per reaction and approximately
six copies, and sometimes even as few as three copies, of target RNA tested positive in our assay. Thirty-five throat
swabs from ill birds were tested: 33 samples tested positive using this assay. In comparison, 27, 13 and 19 samples
tested positive using conventional RT-PCR, antigen-capture ELISA and virus isolation, respectively. To evaluate
further the sensitivity of this real-time RT-PCR, a standard panel and 60 H5N1 isolates that contained different clades
of influenza virus A/H5N1 were tested and all tested positive. To evaluate the specificity of the assay, 60 throat swabs
from patients infected with influenza virus A H1 were tested; all were negative. Thirteen other viruses were also tested
and all tested negative.

Résumé : The Asian lineage highly pathogenic avian influenza (HPAI) H5N1 virus is a known pathogen of birds. Only
recently, the virus has been reported to cause sporadic fatal disease in carnivores, and its zoonotic potential has been
dominating the popular media. Attention to felids was drawn by two outbreaks with high mortality in tigers, leopards
and other exotic felids in Thailand. Subsequently, domestic cats were found naturally infected and experimentally
susceptible to H5N1 virus. A high susceptibility of the dog to H3N8 equine influenza A virus had been reported earlier,
and recently also HPAI H5N1 virus has been identified as a canine pathogen. The ferret, hamster and mouse are suitable
as experimental animals; importantly, these species are also kept as pets. Experimental intratracheal and oral infection
of cats with an HPAI H5N1 virus isolate from a human case resulted in lethal disease; furthermore, cats have been
infected by the feeding of infected chickens. Spread of the infection from experimentally infected to in-contact cats has
been reported. The epidemiological role of the cat and other pet animal species in transmitting HPAI H5N1 virus to
humans needs continuous consideration and attention.

Résumé : Despite continuing research efforts, knowledge of the transmission of the highly pathogenic avian influenza
(HPAI) virus still has considerable gaps, which complicates epidemic control. The goal of this research was to develop
a model to back-calculate the day HPAI virus is introduced into a flock, based on within-flock mortality data. The
back-calculation method was based on a stochastic SEIR (susceptible (S) - latently infected (E) - infectious (I) -
removed (= dead; R)) epidemic model. The latent and infectious period were assumed to be gamma distributed.
Parameter values were based on experimental H7N7 within-flock transmission data. The model was used to estimate the
day of virus introduction based on a defined within-flock mortality threshold (detection rule for determining AI). Our
results indicate that approximately two weeks can elapse before a noticeable increase in mortality is observed after a
single introduction into a flock. For example, it takes twelve (minimum 11 - - maximum 15) days before AI is detected
if the detection rule is fifty dead chickens on two consecutive days in a 10000 chicken flock (current Dutch monitoring
rule for notification). The results were robust for flock size and detection rule, but sensitive to the length of the latent
and infectious periods. Furthermore, assuming multiple introductions on one day will result in a shorter estimated
period between infection and detection. The implications of the model outcomes for detecting and tracing outbreaks of
H7N7 HPAI virus are discussed.

Résumé : Influenza infections are a major cause of mortality and morbidity worldwide. Therefore, there is a need to
establish vaccines and immunization protocols that can prevent influenza infections. Herein, we show that one
intranasal (IN) followed by one intramuscular (IM) immunizations with a combination of cell culture produced
hemagglutinin (HA) antigens derived from 3 different influenza strains induced significantly higher serum
hemagglutination inhibition (HI) and serum IgG antibody titers as well as Tcell responses, compared to 2 IM, 2 IN or 1
M followed by 1 IN immunizations. Moreover, while 2 IM immunizations did not induce any antibody responses in
nasal secretions or cervical lymph nodes, which drain the nasal mucosa, IN immunizations alone or in combination with
IM immunization induced mucosal and local responses. These data show that the IN followed by IM immunization
strategy holds promise to significantly raise serum and local antibody and T cell responses against seasonal influenza
strains, and possibly pandemic influenza strains, for which no pre-existing immunity exists.

Résumé : Aim: To explore attitudes to influenza immunisation and rates of uptake among staff working in acute
hospitals in the UK. Method: A cross-sectional survey of 11 670 healthcare workers in six UK hospitals was carried out
using a postal questionnaire. Results: Among 6302 responders (54% of those mailed), 19% had taken up influenza
immunisation during winter 2002/3. Vaccination was well tolerated, with a low prevalence of side effects (13%) and
associated time off work (2%). The majority of subjects who accepted vaccination (66%) were most strongly influenced
by the personal benefits of protection against influenza. Prevention of sickness absence and protection of patients were
the prime motivation for only 10% and 7% of subjects, respectively. Among 3967 who declined vaccination, the most
common primary demotivators were concern about safety (31%) and efficacy (29%). 22% were most strongly deterred
by lack of time to attend for vaccination. Free text answers indicated that 37% declined because of a perceived low ratio
of personal benefits to adverse effects. Subjects said they would be persuaded to take up vaccination in future by easier
access (36%), more information about personal benefit and risk (34%) and more information about effects on staff
absence (24%). Conclusions: These findings indicate that the uptake of influenza immunisation among UK healthcare
workers remains low. There is some scope for increasing uptake by improving accessibility and encouragement from
professional peers. However, the results suggest that perception of small personal benefit in relation to risk mitigates,
importantly, against higher uptake of routine annual influenza vaccination. Thus, resource might better be allocated to
ensuring efficient management in epidemic years. The effect of publicity about pandemic influenza on risk perception
and vaccine uptake among healthcare workers during winter 2005/6 warrants further study.

Résumé : In response to recent outbreaks of H5N1 highly pathogenic avian influenza virus (HPAIV), the development
of an effective H5N1 influenza vaccine is urgently important. We assessed the efficacy of two inactivated H5N1
whole-virus vaccines, rgHK213/03 and rgVNJP1203/04, generated by reverse genetics in a mouse model in the
presence or absence of aluminum hydroxide (alum) adjuvant. Mice immunized with rgHK213/03 vaccine produced
sufficient levels of serum antibodies that were cross-reactive to recent heterologous HPAIV-H5N1 virus,
A/Turkey/12/06. The vaccinated mice also elicited protective immunity against challenge with both homologous and
heterologous HPAIV-H5N1 viruses. These immune responses were enhanced by addition of alum adjuvant, resulting in
antigen sparing of vaccine. On the other hand, mice immunized with rgVNJP1203/04 vaccine had low levels of serum
antibodies and less protective immunity than that elicited with rgHK213/03 vaccine regardless of addition of alum
adjuvant. Our study suggests that rgHK213/03 vaccine is still useful as a backup vaccine for recent H5N1 viruses and
that if rgVNJP1203/04 vaccine is employed, more vaccine antigen would be necessary to induce sufficient immunity.

Résumé : The 1918 influenza pandemic was a catastrophic series of virus outbreaks that spread across the globe. Here,
we show that only a modest change in the 1918 influenza hemagglutinin receptor binding site alters the transmissibility
of this pandemic virus. Two amino acid mutations that cause a switch in receptor binding preference from the human
<alpha>-2,6 to the avian <alpha>-2,3 sialic acid resulted in a virus incapable of respiratory droplet transmission
between ferrets but that maintained its lethality and replication efficiency in the upper respiratory tract. Furthermore,
poor transmission of a 1918 virus with dual <alpha>-2,6 and <alpha>-2,3 specificity suggests that a predominant human
<alpha>-2,6 sialic acid binding preference is essential for optimal transmission of this pandemic virus. These findings
confirm an essential role of hemagglutinin receptor specificity for the transmission of influenza viruses among
mammals.

Résumé : After intranasal, subcutaneous, or intraperitoneal infection with Dhori virus (DHOV), adult mice developed a
fulminant and uniformly fatal illness with many of the clinical and pathologic findings seen in mice infected with H5N1
highly pathogenic avian influenza A virus. Histopathologic findings in lungs of DHOV-infected mice consisted of
hemorrhage, inflammation, and thickening of the interstitium and the alveolar septa and alveolar edema.
Extra-pulmonary findings included hepatocellular necrosis and steatosis, widespread severe fibrinoid necrosis in
lymphoid organs, marked lymphocyte loss and karyorrhexis, and neuronal degeneration in brain. Similar systemic
histopathologic findings have been reported in the few fatal human H5N1 cases examined at autopsy. Because of the
relationship of DHOV to the influenza viruses, its biosafety level 2 status, and its similar pathology in mice, the
DHOV-mouse model may offer a low-cost, relatively safe, and realistic animal model for studies on the pathogenesis
and management of H5N1 virus infection.

Résumé : Wild birds, particularly waterfowl, are a key element of the viral ecology of avian influenza. Highly
pathogenic avian influenza (HPAI) virus, subtype H5N1, was first detected in poultry in November 1996 in southeast
China, where it originated. The virus subsequently dispersed throughout most of Asia, and also to Africa and Europe.
Despite compelling evidence that the virus has been dispersed widely via human activities that include farming, and
marketing of poultry, migratory birds have been widely considered to be the primary source of its global dispersal. Here
we present a critical examination of the arguments both for and against the role of migratory birds in the global
dispersal of HPAI H5N1. We conclude that, whilst wild birds undoubtedly contribute to the local spread of the virus in
the wild, human commercial activities, particularly those associated with poultry, are the major factors that have
determined its global dispersal.

Résumé : Influenza viruses are etiological agents of deadly flu that continue to pose global health threats, and have
caused global pandemics that killed millions of people worldwide. The availability of neuraminidase inhibitors and
attenuated vaccines improves our ability to defend against influenza, but their benefits can be significantly limited by
drug-resistance and virus mutations. Nucleic acid-based drugs may represent a promising class of antiviral agents that
could play a role in the prevention and treatment of influenza. Efficacy studies in animals have shown that ds RNA,
such as poly ICLC can provide effective and broad-spectrum prophylaxis against lethal challenges against various
strains of influenza A virus. Furthermore, similar level of antiviral protection in mice can be provided by using short
fragments of oligonucleotides that induce antiviral immunity. Finally, influenza virus expression can also be
specifically inhibited or suppressed using antisense oligonucleotides that bind to viral mRNA encoding key viral
proteins. The versatility and potency of nucleic acid-based drugs make them potential drug candidates for used in
seasonal or pandemic influenza situations.

Résumé : Influenza A/H5N1 (avian influenza) has now caused 258 human infections (as of November 13, 2006), with
an approximate 50% mortality rate. Because the virus is novel in terms of antigenic type and causes infection and
illness, and because humans have no pre-existing immunity, the conditions for a possible pandemic exist. Additionally,
wild migratory birds appear to be spreading the virus across ever larger geographic areas, and newer clade 2 influenza
A/H5N1 viruses have begun to emerge. The US Congressional Budget Office has formally modeled the likely
consequences of pandemic influenza and estimates that up to 2 million of the US population might die, with up to 40%
of all workers ill for as long as 3 or more weeks. This brief overview will review basic virologic, immunologic and
epidemiologic information relevant to understanding and preparing for this threat. In particular, the role of avian
influenza vaccines will be reviewed.

Résumé : The frequency of H5N1 avian influenza outbreaks in China and Eastern Europe has raised concern in the
world health community regarding the potential for an influenza pandemic. Efforts to monitor the disease will only
provide minimal warning in a global society, and steps must be taken to prevent the morbidity and mortality associated
with past pandemics. The current stockpiling of antibody-inducing "bird flu" vaccines assumes the strain that emerges
will be the same as strains currently circulating. We propose a novel consensus-based approach to vaccine development,
employing a DNA vaccine strategy that can provide more highly cross-reactive cellular immunity against lethal
influenza infection. We show such constructs can induce strong cellular immunity against H5 influenza antigens.

Résumé : The performance of a diagnostic microarray (the MChip assay) for influenza was compared in a blind study
to that of viral culture, reverse transcription (RT)-PCR, and the QuickVue Influenza A+B test. The patient sample data
set was composed of 102 respiratory secretion specimens collected between 29 December 2005 and 2 February 2006 at
Scott & White Hospital and Clinic in Temple, Texas. Samples were collected from a wide range of age groups by using
direct collection, nasal/nasopharyngeal swabs, or nasopharyngeal aspiration. Viral culture and the QuickVue assay were
performed at the Texas site at the time of collection. Aliquots for each sample, identified only by study numbers, were
provided to the University of Colorado and Vanderbilt University teams for blinded analysis. When referenced to viral
culture, the MChip exhibited a clinical sensitivity of 98% and a clinical specificity of 98%. When referenced to
RT-PCR, the MChip assay exhibited a clinical sensitivity of 92% and a clinical specificity of 98%. While the MChip
assay currently requires 7 to 8 h to complete the analysis, a significant advantage of the test for influenza virus-positive
samples is simultaneous detection and full subtype identification for the two subtypes currently circulating in humans
(A/H3N2 and A/H1N1) and avian (A/H5N1) viruses.

Résumé : We conducted a cohort study to identify the risks and outcomes of influenza A (H3N2) pneumonia. Of the
145 patients studied, 10 (7%) had influenza A pneumonia. Logistic regression identified multiple comorbidities
(P<.001) and diarrhea at the initial presentation (P =.001) as associated risks. Infection with influenza A (P =.01) and
receipt of inadequate antimicrobial therapy (P =.005) were predictors of mortality.

pays de l' Union Europeenne (UE). De telles infections etaient confirmees chez des oiseaux en Grece, mais apres
investigation, aucun cas humain n' a ete confirme. Cependant, les enquetes et les controles de masse qui ont ete realises
autour des cas infectes et des deces lors de l' epidemie survenue en Turquie en decembre 2005 et janvier 2006 restent
dans les memoires et temoignent de ce qui aurait pu se passer en Grece ou dans d' autres pays de l' UE

Résumé : Suite a l' apparition du virus A/H5 chez des oiseaux domestiques et sauvages en Azerbaidjan en fevrier 2006,
deux clusters de cas possibles de grippe aviaire humaine (HAI) dus a des cas de A/H5N1 ont ete detectes et rapportes au
bureau regional Europe de l' OMS (Organisation mondiale de la sante) par le ministere de la Sante au cours des deux
premieres semaines de mars 2006. Le 15 mars 2006, l' OMS a forme une equipe internationale, comprenant des experts
en controle d' infection, en gestion clinique, en epidemiologie, en microbiologie et en communication, afin d' aider le
ministere de la Sante dans ses investigation et ses actions de reponse. Apres une surveillance active, 22 personnes - dont
6 decedees - reparties sur 6 districts, ont fait l' objet d' une recherche de grippe aviaire. L' investigation a permis de
mettre en evidence 8 cas d' infection par le virus A/H5N1 confirmes par le Centre Collaborateur OMS de la Grippe et
un cas probable pour lequel aucun echantillon n' etait disponible. Les cas appartenaient a deux clusters independants sur
le plan epidemiologique identifies dans les districts de Salyan (sept cas confirmes, dont 4 deces) et de Tarter (un cas
confirme et un cas probable, tous deux fatals). Des contacts etroits et le fait de plumer des cygnes infectes ont ete
consideres comme la source la plus plausible d' exposition au virus A/H5N1 pour le foyer de Salyan, malgre les
difficultes a recueillir des informations au cours de l' investigation, du fait de la pratique d' activites illegales au cours
desquelles une exposition a pu se produire (chasse et vente d' animaux sauvage et de produits derives). Ces cas
constituent la premiere epidemie a l' echelon mondial au cours de laquelle des oiseaux sauvages sont la source la plus
probable d' infections humaines par le virus A/H5N1. La mobilisation rapide de ressources pour contenir la
dissemination du virus A/H5 dans les deux districts est le resultat d' une collaboration entre le ministere de la Sante, l'
OMS et ses partenaires internationaux. Les activites de controle ont ete menees au moyen d' un laboratoire de terrain ou
il etait possible de detecter le virus A/H5 en temps reel par RT-PCR. La surveillance quotidienne chez l' habitant
entreprise dans les deux districts affectes rend peu vraisemblable l' eventualite de nouveaux cas humains de grippe
aviaire non detectes. (R.A.)
