Epizootic situation on IRT of cattle in the territory of the Moscow and Tver regions

Abstract

Currently, despite all the measures taken by the Ministry of Agriculture of the Russian Federation and the Rosselkhoznadzor to regionalize the territory of the Russian Federation for infectious animal diseases, the status of subjects for many of them has not yet been determined. As of March 09, 2021, the status of infectious bovine rhinotracheitis has not been determined for 69 subjects of the country, including for the Moscow and Tver regions. At the same time, the official veterinary literature indicates the widespread distribution of cattle IRT in our country. In fact, the current epizootic situation for this disease both on the territory of the whole country and in individual subjects remains unknown. In this paper, we tried to clarify the epizootic situation of infectious bovine rhinotracheitis in the Moscow and Tver regions of the Russian Federation using active monitoring methods. As a result of sample studies in farms located on the territory of these regions, it was found that the results of serological studies do not always correlate with the status of vaccination of animals. In some farms, animals are vaccinated against cattle IRT, however, the results of serological studies in these farms indicate that the young animals in these farms are not immune to IRT. This fact clearly indicates the weak effectiveness of anti-epizootic measures aimed at specific prevention of infectious rhinotracheitis of cattle in individual livestock farms and the lack of a unified approach to the organization of this issue as a whole. Nevertheless, we found that the livestock farms in which the circulation of the cattle IRT virus is registered are not evenly located on the territory of the surveyed regions. Such farms are located in the north, north-west, south-west and east of the Moscow Region. In the Tver region - in the south-west, north-west, north-east and east of the region.
