ВЛИЯНИЕ АНТИГЕННОЙ ВАРИАБЕЛЬНОСТИ ВИРУСА ВИРУСНОЙ ДИАРЕИ - БОЛЕЗНИ СЛИЗИСТЫХ ОБОЛОЧЕК КРУПНОГО РОГАТОГО СКОТА, НА РЕЗУЛЬТАТЫ СЕРОЛОГИЧЕСКОЙ ДИАГНОСТИКИ
Abstract
The serological investigations of 7 large dairy farms in serum neutralization test with use as an antigene
strains of two subgenotypes of a virus belonging to first genotype have revealed presence of antibodies to
both subgenotypes showing of circulation them among a concrete population of animals. The distinctions in
frequency of detection and antibodies titers, and also seroconversion in imported and aborigen animals to
both subgenotypes of virus explaining epidemiological situation in a concrete farm on the moment of investigations
are established. The risk of occurrence of repeated BVD outbreaks in permanently infected herds
is connected to input of new animals infected with differing subgenotypes of a virus.
