| Popis: | Introduction . BoHV-4 is poorly understood. Data on the circulation of the virus among animals and its role in infectious diseases insufficient. Aimes and goals . Development of real-time PCR for detecting the BoHV-4 and studying the frequency of its presence in samples from sick animals. Material and methods . The nucleotide sequences of the glycoprotein L gene served as a target for amplification. The sequences of reference strains published in GenBank were used to analyze and design the primers. Studies were conducted in 3 regions of Western Siberia on 5 large dairy farms. Results . 27.7% of samples contained the virus. The virus was present as a monoagent in nasal cavity of calves (80.0%), lungs (46.2%) and bronchial lymph nodes (38.5%) in pneumonia. In the cases of diarrhea the virus was detected in 20%, and in cows with gynecological pathology in 10.0%. In respiratory diseases of calves the virus was detected in association with BoHV-1 (21.6%) and BoCV (20.3%), and in gynecological pathology of cows with BVDV1 (6%). Discussion . According to the phylogenetic analysis of 5 identified virus isolates, four belonged to the American branch and one to the European branch. The circulation of American strains occurred in the territory of the Republic of Kazakhstan (1), Tyumen (1) and Novosibirsk (2) regions, and the European - in the Novosibirsk region. Conclusion . The search for viruses involved to the infectious pathology, as well as studying the genetic diversity of viruses circulating on a particular farm including imported from other countries, is relevant. |
