genetic diversity of pestivirus isolates in cattle from western austria.the genetic diversity of bovine viral diarrhoea virus (bvdv) isolates in infected cattle from tyrol and vorarlberg (austria) was investigated. blood samples were collected within the compulsory austrian bvdv control programme during 2005 and 2006. the 5'-untranslated region (5'-utr) and partially the n-terminal autoprotease (n(pro)) were amplified by one-step reverse transcriptase-polymerase chain reaction (rt-pcr) and the pcr products were subsequently sequenced. phylogenetic analysis based on ...200919019571
[seroprevalence of antibodies to ruminant pestiviruses in sheep and goats in tyrol (austria)].in this study 2058 blood samples from sheep of 150 flocks from the province of tyrol were tested by elisa and serum neutralisation tests for antibodies to ruminant pestiviruses. in the elisa, positive results were obtained with 34.9% of individual sheep sera and in 89.3% of the sheep flocks. the prevalence in sheep and sheep flocks varied according to areas. seroprevalence of pestiviruses was significantly (p < 0.05) higher in small ruminants pastured during summertime on the alps. comparative n ...200616555484
