This is due to the high infection of livestock and large economic damage in affected farms [1–3]. Leucosis is a chronic tumor disease caused by an RNA-containing virus of the <em>Retroviridae</em> family. The disease is characterized by uncontrolled reproduction of immature hematopoietic cells [4, 5]. The objective is to assess in dynamics the indicators of cattle infection with the leucosis virus and the incidence of leucosis in farms of all categories of the Russian Federation in the period of 2000–2018. The data of the analysis of the epizootic situation for leucosis in cattle in farms of all categories of the Russian Federation for 2000-2018 are presented. Over this period of time, the number of diagnostic serological studies in the immunodiffusion reaction increased 1.88 times in all subjects. According to the results of epizootological monitoring in farms of all categories of the Russian Federation, the rates of infection of the bovine leucosis virus decreased 1.89 times, the incidence rates decreased 2.02 times. At present, the epizootic situation has improved markedly, but so far there are problems with incomplete release of farms from leucosis in cattle. It is necessary to continue work on the elimination of this dangerous chronic disease in farms of all categories in the territory of the Russian Federation.</p&gt;}, number={14}, journal={KnE Life Sciences}, author={Kuzmin, Vladimir and Gulyukin, Mikhail and Gulyukin, Aleksey and Metlin, Artyom and Prosvirnin, Gleb and Tsyganov, Andrey and Orekhov, Dmitriy and Makavchik, Svetlana and Khakhaev, Ivan and Evglevskiy, Dmitriy}, year={2019}, month={Nov.}, pages={666–673} }
