Abstract. This article summarizes the results of laboratory studies of acute respiratory viral infections of cattle in agricultural enterprises of the Ural Federal district and the Udmurt Republic. The purpose of the research was to show the spread of respiratory viral infections in cattle in various regions and the significance of laboratory diagnostics in this pathology. According to research data 815 samples for the period 2018–2020 a variety of combinations of mixed respiratory viruses in animals was detected using biomaterials from different age patients and patients with respiratory diseases of cattle from agricultural enterprises of the Ural Federal district, the Volga Federal District and the Udmurt Republic using polymerase chain reaction method, indirect hemagglutination reaction, hemagglutination inhibition reaction, ELISA, and enzyme immunoassay. Scientific novelty. The etiological structure of mixed acute respiratory viral infections in cattle in agricultural enterprises in four regions of the Ural Federal District, the Volga Federal District and the Udmurt Republic in 2018–2020 was studied using modern diagnostic technologies. Results. In the Ural Federal District, the Volga Federal district and the Udmurt Republic, 80 % of cases of acute respiratory diseases were caused by bovine viral infections, mainly representatives of 2 families of viruses whose genome is represented by an RNA molecule (paramixoviruses, togaviruses) and a family of viruses whose genome is represented by a DNA molecule (herpesviruses,). The leading place among acute respiratory infections was occupied by infectious rhinotracheitis of cattle.
Keywords: acute respiratory viral infections, infectious rhinotracheitis, viral diarrhea, type 3 parainfluenza, respiratory syncytial infection, laboratory diagnostics, cattle.
