morphologic lesions in type 2 bvdv infections experimentally induced by strain bvdv2-1373 recovered from a field case.widespread outbreaks of severe acute bvdv, some associated with hemorrhagic syndrome (hs), were reported in quebec and ontario in 1993. these outbreaks caused significant economic hardship in infected herds. in the ontario outbreak 150 dairy, 600 beef and 100 milk and grain fed veal herds were affected with losses estimated at $40000-$10000 per herd in lost animals, milk production, abortions and genetics. fever, pneumonia, diarrhea, and sudden death occurred in all age groups of cattle. abortio ...200011042409
the 5'-untranslated region sequence of a potential new genotype of bovine viral diarrhea virus.the 5' untranslated region (utr) of several bovine viral diarrhea virus (bvdv) isolates from the severe quebec outbreak was amplified by polymerase chain reaction (pcr) and sequenced. sequences revealed the loss, for the bvdv type ii isolates, of an internal psti restriction site, which is present in all known bvdv type 1 5' utr sequences. a single restriction enzyme digestion (psti) of an aliquot of pcr product allowed us to differentiate bvdv type i and bvdv type ii.19957646359
