Prevalence of the Viral Infections Among Calves in Livestock Farms Located in the Samarkand Region of Uzbekistan

Abstract

The article presents the information of serological studies utilizing the RNGA strategy for the presence of antibodies to the infections of infectious rhinotracheitis, viral diarrhea, rota- and coronavirus infection and parainfluenza-3 in cattle. 473 blood sera from unvaccinated cows and calves under 1 year old from 25 farms within the Samarkand region of the Republic of Uzbekistan were considered. The results of the study showed that there was a wide range of virus positivity among animals, with antibody titers falling between 1.6-53 log2 The most common infections observed in animals are caused by rotavirus, resulting in diarrhea, as well as infectious rhinotracheitis. To a lesser extent, animals may also contract coronavirus and parainfluenza-3, with respiratory syncytial infection virus being the least frequent.
