Summary. African swine fever is an acute highly contagious disease of pigs. Allergic and autoallergic reactions play major role in pathogenesis and immunogenesis at ASF. Virus has a high survival rate in the environment: it is stored in the soil from 112 days (summer-autumn) to 200 days (winter-spring), in feces -up to 160 days, in the urine - up to 60 days, in the corpses - from 17 to 70 days, in frozen meat of diseased pigs during storage - to 155 days and in smoked ham - up to 180 days. Temperature range of pathogen stability is: 5°C - to 7 years, 18-20°C - 18 months, 37°C - 30 days, 50°C - up to 1 hour. One of the mandatory items of anti-epizootic measures to eliminate the outbreak of African swine fever within the quarantine measures is disinfection. Since 2007 new disinfectants studied in National Research Institute for Veterinary Virology and Microbiology of Russia were successfully used for the disinfection of infected with ASF virus agricultural objects. Proposed by the authors Kemicyd has a prolonged effect due to the presence in its composition of polyhexamethylene guanidine hydrochloride, which forms a microfilm on the treated surface, safe for the materials, but destructive for microorganisms. Role of the use of previously developed disinfectants against the African swine fever (ASF) in the territory of the Russian Federation, as well as the use of disinfectants with higher efficacy and economic costs is presented in the article. Authors found that properly used disinfectants significantly increase the efficiency of veterinary-sanitary measures for the elimination of disease foci.

Keywords: African swine fever, outbreak, focus, endangered area, virus stability, veterinary and sanitary measures, disinfection, disinfectant, Kemicyd, microfilm.
