Abstract

This article analyzes statistical data on the diagnosis of the AD virus by state veterinary laboratories of the Russian Federation for the period from 2019 to 2021. Veterinary specialists determine the presence of the virus in the biological material by molecular genetic methods, immunofluorescence reaction and using a biological test on white rabbits, the presence of antibodies by post-infection and post-vaccination serological methods of research. The AD virus has many hosts, so annual epidemiological monitoring is carried out in various animal species: pigs, cattle and small cattle, cats, dogs and fur-bearing animals. During the analyzed period, according to the annual reports of state veterinary laboratories in the form 4 vet, the Aujeszky's disease virus was detected by PCR in 0,26 %, while post-infection antibodies were detected in 6,43 %. The level of post-vaccination immunity in the population of vaccinated animals from 2019 to 2021 averaged 92 %. The ELISA method was used 15 times more often than PCR, which is due to the use of the method for ease of screening and lower labor costs for mass monitoring.
