To investigate the degree of genetic variability of bovine leukemia virus (BLV) strains circulating in Croatia, 29 isolates from the six largest dairy farms were examined by PCR for a segment of the gp51 env gene, followed by DNA sequencing and phylogenetic analysis. The nucleotide sequences were compared with other previously characterized BLV strains from(More)

In this report a persistently infected cow was under surveillance for three years. In that period the level of antibodies and level of viremia were determined. Persistent infection was confi rmed in blood serum samples taken at 3 week intervals and tested on the virus antigen by antigen enzyme-linked immunosorbent assay and by inoculation in cell culture,(More)
BACKGROUND Bovine viral diarrhea is a contagious disease of domestic and wild ruminants and one of the most economically important diseases in cattle. Bovine viral diarrhea virus belongs to the genus Pestivirus, within the family Flaviviridae. The identification and elimination of the persistently infected animals from herds is the initial step in the(More)
