Abstract
Relevance. Viral diarrhea — mucosal disease of cattle — is widespread throughout the world, including Russia. The virus causes immunosuppression, pathology of the gastrointestinal and respiratory tract. But the greatest economic damage is due to the culling of heifers and lactating cows as a result of pathologies of the reproductive system. The disease is included in the "List of contagious and other animal diseases", approved by order No. 62 of the Ministry of Agriculture of the Russian Federation (dated March 9, 2011 (as amended on September 25, 2020)).
Methods. Based on the data obtained from the official annual reports of state veterinary laboratories in the 4-vet form for 2021, provided to the Federal State Budgetary Institution TsNMVL, an analysis of the epizootic situation and the circulation of the viral diarrhea (mucosal disease of cattle) in livestock farms of the Russian Federation was carried out.
Results. The article presents the results of epizootological monitoring conducted in the territory of the Russian Federation in 2021. More than 50,000 samples of biological and pathological materials have been submitted to state veterinary laboratories for analysis. Mostly, the laboratory received blood serum for testing for the presence of post-infection and post-vaccination antibodies by ELISA. There were 5,244 positive results in 26 subjects. The most intense epizootic situation is in the Central and North Caucasian Federal Districts (49% and 38% of positive results from the total number of positive cases, respectively).
