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

Forty pestivirus isolates sampled from cattle in Turkey between 2002 and 2007 were characterized according to 5′ untranslated region (5′UTR) sequences and autoprotease (N^pro) 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.
