Foreward
The year 2014 has been an exciting year at AHRI. Several large research projects were successfully conducted. The meningococcal carriage study in Arbaminch completed its field work and samples are being analyzed at both AHRI and Oslo collaborating laboratories. STREAM trial has been enrolling patients with multidrug resistant tuberculosis at both AHRI and St Peter's Specialized TB Hospital. Gondar University joined in as a third site to accelerate patient recruitment. The trial will move into Stage 2 in 2015 with more stringent procedures put in place to ensure high standards that can meet registration requirements. The Regional Bioequivalence Clinical Center at AHRI successfully completed two protocols and is preparing to apply for WHO prequalification. It is hoped that site visits will be conducted in 2015 to initiate the process. A total of 74 projects were running at the Institute in 2014. The number of publications topped 53, the largest in a year in the history of the Institute! This was a result of extensive collaboration of AHRI researchers with University and Health Facility colleagues in various parts of the country, often centered around postgraduate student training at AHRI and elsewhere. Most of the publications arose from work conducted at AHRI laboratories. The progressive increase in the number of AHRI publications is one sign of the expanding role and increasing maturity of AHRI postdocs and senior research assistants. It shows that AHRI has managed to generate competent research leaders who can realize the further expansion of the Institute and its extended hub function. Postgraduate training was further strengthened with three programs in 2014. These were the Emory-Ethiopia TB Research Training (EETBRT) Program funded by the National Institutes of Health Fogarty program, the Biomedical Sciences Postgraduate Training Program (BSPP) funded by Sida and the Brighton-Sussex Global Health Centre funded by the Welcome Trust where AHRI hosts students for co-supervision and research support in collaboration with Addis Ababa University and the other partners. The BSPP will enable 10 PhD candidates to acquire advanced skills in molecular techniques in Sweden. It is expected that the graduates will help catalyze biomedical research at regional universities in Ethiopia. To accommodate the increasing number of PhD students, AHRI has taken steps to acquire more laboratory equipment, more lab space and better access to reagents and supplies. Two new large autoclaves were received in 2014 and are being installed, both donated by Heal TB/USAID to support AHRI research. Field mobility will improve with the acquisition of several new vehicles purchased through Norad support. In the last 10 years, 73 MSc and 21 PhD students graduated from AHRI. One of the strategic aims of AHRI is to stay linked with as many of them as possible to strengthen collaboration and promote research in the universities and health facilities where many of them are currently employed. A survey is in progress to map where the alumni are. AHRI aspires to strengthen its hub function through continued collaboration with its international partners in advanced laboratories and its link with national institutions engaged in research and training. An example of a practical output in 2014 is the establishment of an immunology laboratory at the Amhara Regional Laboratory in Bahir Dar. Butajira Hospital received laboratory equipment to strengthen its research capacity in HIV, malaria and TB from EDCTP as a satellite sister institution of AHRI. AHRI received financial support from the MoH to strengthen clinical research. It plans to use this to enable peripheral hospital and university laboratories such as at Arba minch and Harar to conduct collaborative research (linked to postgraduate training whenever possible) on arboviral diseases, antimicrobial sensitivity and hepatitis, all significant problems at the sites selected. AHRI researchers have contributed to national and international scientific conferences and participated in several committee tasks at various levels. AHRI contributed to the WHO Meningitis Epidemic Guideline development in 2014. The AHRI Neglected Diseases Team is a member of the National Taskforce for NTD Control and has contributed to the national Master Plan and mapping of the national NTD distribution. The Leprosy team is similarly involved in the National Leprosy Program. The TB team promotes close links with regional programs and supports government initiatives. In 2014, the Capacity Building for Operational Research in TB (CORE-TB) program hosted at AHRI with financial support from TBCARE/USAID successfully achieved a milestone: all six first cohort research teams presented their findings at the 2014 International TB Conference in Barcelona and published articles in the peer review online journal Public Health Action! The second cohort of six other regions has completed its data collection and entered the analysis phase. The evidence generated by each team is likely to be of immediate benefit in solving the local problems because the research was led by program managers and responded to research questions posed by them. With increasing number of graduates from the universities and a rising demand for research space, AHRI is obliged to seek means to stay relevant and useful. One persistent challenge has been its administrative inefficiency and lethargic handling of logistic constraints. The Institute's management was strengthened this year through the establishment of a Procurement and a Finance Unit under the Scientific Director's Office. A Procurement and Finance Coordinator supervises the performance of the two units. Particular attention has been paid to ensure strict adherence of the units to good practice standards. It is expected that progress will be faster as team members build experience in handling assignments and improve efficiency. The Ethiopian government's strategy for Science, Technology and Innovation is to lay the ground work for a knowledge based economy of the future today. This requires institution building. AHRI had submitted an application to the Ministry of Health to be formally established as a Government Research Institute focused on biomedical, clinical and translational research serving as a sister Institute to the Ethiopian Public Health Institute. A draft legislation was developed by the legal unit of the Ministry of Health in consultation with AHRI and was subjected to stakeholder review. The appropriate Government organ is expected to deliberate on the document and take decision soon. The achievements of AHRI were only possible because of the continued support of the Federal Ministry of Health, Ethiopia, and its core funders Norad and Sida. AHRI is proud of its national and international research partners without whose contributions AHRI would not have reached this stage. Particular thanks go to the postgraduate students whose achievements we celebrate here. The AHRI/ALERT Ethics Review Committee and the AHRI Scientific Advisory Board are two very significant contributors to the quality of work at AHRI that have managed to keep it on track and to foster its national and international reputation. This year, the Ethiopian government provided AHRI with research funds to address clinical challenges. This move, building on the support of all the partners mentioned above, is very likely to lead to a new era for AHRI in the next years. Tuberculosis (TB) Team
The TB team; which was formally established in July, 2006, is the biggest team in terms of the number of projects, MSc and PhD students as well as research staff. In 2014, there are 6 projects on diagnostics, 13 on epidemiology, 4 on biomarker and 11 on basic biomedical research; which gives a total of 34 projects. Some of these projects are just in the initial phase, most are half way while the remaining are on their final phase. (Please see the full list of projects and status.) Diagnostics Research

The project, "Mask sampling as a method to detect tubercle In the Mycobacterium tuberculosis complex bacilli from smear negative pulmonary TB patients" (MTBC), a possible role for strain diversity in is funded by AHRI core. human tuberculosis (TB) is increasingly being suggested from work in various infection models. Significant differences among MTBC lineages have been reported in terms of their propensity to cause secondary cases in different human population, their progression to active disease in recently exposed household contacts, and their recognition by the human immune system. Most other related studies have reported associations between phenotypes. Additionally, the emergence of resistance to anti TB drugs, and particularly multidrug-resistant tuberculosis (MDR-TB) has National ethics review committees.

Nonetheless, the causative agent for TB among cattle owners was invariably MTB and not M. A critical component of vaccination is to generate bovis. Thus if transmission occurs between antigen-specific humans and cattle in Ethiopia, it is most likely due lymphocytes of sufficient quantity and quality to to Mtb and potentially moves from humans to provide long term protection against re-infection. In cattle (and potentially subsequently back to spite of considerable advances regarding immune human). Alternatively, the observed associations response to Mtb, it is still challenging to interpret between cattle and human TB may be due to other results of vaccine trials.

AHRI Bacteriology team was established in 2006 to conduct epidemiological and molecular studies on common bacterial diseases. The aim of establishing the bacteriology team is to lead, plan and coordinate research activities related to meningitis, pneumonia, typhoid fever and other infections caused by pathogenic bacteria. Moreover, the team plays a significant role in capacity building activities of AHRI. As a result of this, MSc and PhD students research projects are provided all the necessary support such as supervision, funding and laboratory space at the bacteriology laboratory to conduct their research. The overall goal of the team is to characterize and identify etiologic agents of diseases in different geographical areas of the country so as to provide research based information to policy makers. entitled "Bacterial Meningitis actual disease burden report and disease severity in non-epidemic season in Ethiopia by use of real time  Wude Mihret [Senior Researcher]  Dr. Demissew Beyene [Post-doctoral sequence typing and cytokine detection assay" is integrated with the main study and the student  Tsehaynesh Lemma [Medical Microbiologist] is coordinating this consortium study both at field Dr Mekonnen Teferi [Research Assistant]  Elena Hailu [Research Assistant]  A total of 163 Study participants clinically Biruk Yeshitela [Research Assistant] diagnosed to have bacterial meningitis were recruited from Hawassa, Gondar and Tikur Anbessa University Hospitals.

In 2013 the NTD-Malaria team was involved both in research and professional services to the Federal Ministry of Health (FMoH). As a member of the national Neglected Tropical Disease Control task force, the team was involved in the development of NTDs five year master plan and launching workshop. In addition, the team participated in the preparation of the Map of NTDs in Ethiopia, in the revision and editing of the guideline for Diagnosis, Treatment and Prevention of Leishmaniasis in Ethiopia 2nd edition June, 2013. Research activities comprised three leishmaniasis related projects and three Malaria related projects, and 4 articles in peer reviewed Journals were published. Moreover, the team has contributed in human capacity building; 5 PhD students were linked with the research activities and in collaboration with Addis Ababa University and 1 MSc student thesis was successfully defended.

Molecular Biology of Leishmania Leprosy Team
The Armauer Hansen Research Institute (AHRI) has established the leprosy research team in 2006to lead, plan and coordinate research activities on leprosy. In Ethiopia, it became possible to treat leprosy with a multidrug therapy (MDT) starting from 1982. Although appropriate treatment during the early stages of the disease reduces its progression and spread, poor diagnostics and lack of access to regular health care often mean that many who develop leprosy are treated late in the disease, after disfigurement. As a result of this the incidence of leprosy remains steady as studies conducted in disease endemic countries reported. In spite of the therapeutic success achieved with MDT to cure leprosy patients, still more work is needed to significantly decrease the current new case detection rate. For this reason, AHRI is currently working on the development of new and improved diagnostic tests, investigating the transmission aspect of leprosy to develop new and improved intervention strategies to curb the transmission of leprosy within the community, the immunopathology of leprosy, genetic susceptibility in leprosy and has also launched working on mapping hot spot leprosy areas in Ethiopia alongside with other priority research areas to generate evidence based findings which can be transformed into practice to improve the existing leprosy control strategies.
