физиологического состояния животных, а также от биотипа возбудителя, вызывающего заболевание, различают три формы течения болезни: хроническая инфекция в постнатальный период; инфекция у стельных коров; персистентная инфекция и болезнь слизистых оболочек. <...> Features of the pathogenesis of bovine viral diarrhea. <...> SUMMARY The bovine virus diarrhea widespread in many countries of the world. <...> For genotyping are two types of agent: BVDV-1 and BVDV-2, a putative third type in cattle, named HoBi-like virus or BVDV-3. <...> Depending on age and physiological state of animals, and also on the biotype virus causing the disease, there are three forms of the disease: persistent infection in the postnatal period; infection in pregnant cows; persistent infection and mucosal disease. <...> Newborn calves that were congenitally infected, lagging in growth and development, showing chronic viral diarrhea, and usually die within a few months. <...> From seropositive cows in the 58125-day pregnancy and seronegative cows in the 42114-day pregnancy produced clinically healthy calves that are persistently infected with specific virus isolates, but they remain completely seronegative to all strains of the bovine virus diarrhea virus. <...> The mucosal disease occurs only persistently infected animals after superinfection with a cytopathogenic virus strains that are antigenically similar to the noncytopathogenic BVDV in persistently infected animal. <...> Влияние антигенной вариабельности вируса вирусной диареи – болезни слизистых оболочек крупного рогатого скота, на результаты серологической диагностики/ О.В.
