Dr. Fabian Leendertz is the Head of research unit “Epidemiology of Highly Pathogenic Microorganisms” at the Robert Koch-Institute Berlin, Germany. He is a veterinarian by training and is specialized on zoonotic diseases. Since 16 years, his main focus are pathogens transmitted between wild non-human primates (especially great apes) and humans. In addition he is investigating the role of rodents and bats as reservoirs for hemorrhagic fever viruses. His approach is multidisciplinary with close collaborations with ecologists, primatologists and medical doctors. All research activities are performed in close collaboration with long term partners from Central and West Africa. Most projects are strongly driven by the One Health concept which embraces human and animal health as well as environmental factors. His work on emerging diseases, including the newly described Bacillus cereus biovar anthracis, has been widely covered by the press.
