Abstract in inglese |
Pestiviruses of cattle include bovine viral diarrhoea types 1 (BVDV-1) and 2 (BVDV-2) plus an emerging group, named HoBi-like pestivirus. In the present paper, an epidemiological survey for pestiviruses circulating in cattle in southern Italy was performed. Molecular assays carried out on a total of 920 bovine samples detected 74 BVDV strains, including 73 BVDV-1 and 1 BVDV-2 viruses. Phylogenetic analysis on partial 5’UTR and Npro sequences revealed the presence of 6 different subtypes of BVDV-1 and a single BVDV-2c strain. BVDV-1 demonstrated high level of genetic heterogeneity, which can have both prophylactic and diagnostic implications. In addition, the detection of BVDV-2c in southern Italy highlights the need for a continuous surveillance for the emergence of pestivirus-induced clinical signs in cattle farms. |
