RESUMO
Five BVDV species 2 (BVDV-2) isolates were detected from cattle in Turkey. Phylogenetic analysis was performed based on the 5' untranslated regions (UTRs) and E2 coding gene regions, respectively. The isolates were closely related to BVDV-2a strains from North America and Canada used as references. This is the first report of the detection of BVDV-2 in naturally infected Turkish cattle. It is important to consider BVDV-2 for planning future BVDV control and vaccination programs in Turkey.

Peste des petits ruminants virus (PPRV, genus Morbillivirus), which causes a severe disease in sheep and goats, has only recently been officially declared to be present in Turkey. We carried out a study to determine the prevalence, distribution, and host range of PPRV in Turkey. A total of 1,607 animals, reared in 18 different locations, were monitored for the presence of antibodies to PPRV and the related virus of large ruminants, Rinderpest virus (RPV). Only two farms had animals that were free of antibody responses to either disease. Prevalence for PPRV infection varied (range 0.87%-82.6%) and was higher in sheep (29.2%) than in goats (20%). The overall antibody responses to PPRV and RPV were 22.4% and 6.28%, respectively. Two PPRVs of lineage 4, which comprises many other PPRVs whose origins are in the Middle East, the Arabian Peninsula, and southern Asia, were isolated from Turkish sheep.
