Genetic diversity of bovine viral diarrhea viruses from the Galicia region of Spain.

ABSTRACT: This study examined the frequency and diversity of bovine viral diarrhoea viruses (BVDVs) infecting cattle in Galicia (northwestern Spain). A total of 86 BVDV strains were typed in samples of serum from 79 persistently infected animals and 3 viraemic animals and of abomasal fluid from 4 fetuses. Samples came from 73 farms participating in a voluntary BVDV control programme. Typing was based on a 288-bp sequence from the 5' untranslated region amplified using primers 324 and 326. Of the 86 strains, 85 (98.8 per cent) belonged to species BVDV-1 and 1 (1.2 per cent) belonged to BVDV-2; 73 strains (84.9 per cent) were typed as BVDV-1b, 2 as BVDV-1e and 6 as BVDV-1d. One strain each was typed as belonging to 1a, 1h, 1k and 1l. The sole BVDV-2 strain was classified as 2a. These results identify
