Abstract:
Two strains of Bovine viral diarrhea virus 2 (BVDV-2) were isolated from calves in northern Italy. Variations in the 5'-untranslated region (UTR) of the genome were studied by primary structure alignment and neighbor-joining method based phylogenetic tree analyses and by palindromic nucleotide substitutions at the three variable loci in the 5'-UTR. Genetic analysis indicated their appurtenance to genovar BVDV-2a. Nucleotide sequence at the 5'-UTR of strain BS-95-II, one of the Italian isolates from healthy calves, showed 98% homology to that of the Japanese isolate OY89, a cytopathic strain derived from cattle with mucosal disease.
