Cattle leukemia is a biological and socio-economic problem of Russian livestock production and is recognized as a potentially dangerous disease for humans. Currently, cattle leukemia is diagnosed in almost all countries of the world. Rate of infection in Russian herds varies from 10 to 70% in different regions and age categories. According to state veterinary report, leukemia was registered in 68 subjects of Russian Federation in 2016. Only Leningrad, Vologda, Arkhangelsk region and Stavropol region have recovered from leukemia. The paper outlines studies carried out in the farms of the Kemerovo region, in particular studies on the resistance of cattle to the leukemia virus, taking into account the age and physiological condition; impact of conditions, seasons on infection and incidence of cattle leukemia virus; features of the polymorphism of the BoLa-DRB3 gene in cattle herds of the Kemerovo region.
