A. Semashko National Research Institute of Public Health27112024413313507052025Copyright © 2025,2025<p>The biography, scientific and social activities of the prominent Russian epidemiologist and microbiologist, the recognized leader of domestic leptospirology, professor Vasily Vasilyevich Ananyin (19121969), have so far remained insufficiently researched and little known to the medical community. His contribution to the development of medicine and biology, as well as national healthcare, has not received sufficient coverage. Based on archival materials, generalized literary sources, the article for the first time provides updated facts of the scientist's biography, traces the stages of his life and scientific activity. The fact of world recognition of V.V.Ananyin's achievements in the development of modern parasitology is highlighted. His role in the development of the leptospirosis laboratory of the N.F.Gamalei Institute of Epidemiology and Microbiology of the USSR Academy of Medical Sciences and the creation of the reference and advisory center of the World Health Organization on its basis is noted.</p>epidemiologymicrobiologyparasitologyzoonosesleptospirosislaboratoryWorld Health OrganizationэпидемиологиямикробиологияпаразитологиязоонозылептоспирозлабораторияВсемирная организация здравоохранения1.Ananyin Vasily Vasilyevich.
