[Detection of bovine herpesvirus 4 DNA in cattle by realtime PCR.].

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.

PHYLOGENETIC ANALYSIS OF BOVINE PESTIVIRUSES DETECTED IN SIBERIA.

The results of phylogenetic analysis of three species of bovine pestiviruses circulating in six regions of Siberia, as well as those detected in fetal embryonic serum (FBS) and continuous cell cultures, are presented. The typing was made based on comparison of sequences from the 5' untranslated region (5'-UTR) of the viral genome. Among the highly productive dairy cattle, circulation of five subtypes of the BVDV1 (a, b, d, f, r) and BVDV2 was established.
