Molecular Characteristics of Bovine Virus Diarrhoea Virus 1 Isolates from Turkey: Approaches for an Eradication Programme

Summary Forty pestivirus isolates sampled from cattle in Turkey between 2002 and 2007 were characterized according to 5′ untranslated region (5′UTR) sequences and autoprotease (Npro) gene sequences. The sampling of Bovine virus diarrhoea viruses (BVDVs) from 15 farms in five different regions indicated that BVDV 1-l (18/40, 45%) was the predominant genotype in Turkey; the samples also contained the genotypes 1-f (10/40, 25%), 1-b (7/40, 17.5%), 1-d (3/40, 7.5%), and 1-a (2/40, 5%), respectively.
