| molecular characterization of porcine circovirus type 2 isolates from post-weaning multisystemic wasting syndrome-affected and non-affected pigs. | porcine circovirus type 2 (pcv2) is recognized as a primary cause in post-weaning multisystemic wasting syndrome (pmws). in this study, both pcv1 and pcv2 types were studied in pigs originating from pmws-affected (+) and non-affected (-) herds from brittany. pcv2 was identified by pcr in 100 % of animals from pmws(+) herds and in 76 % from pmws(-) herds, while pcv1 was not detected. the complete sequences of 38 pcv2 isolates were determined and 23 new variants were identified, displaying between ... | 2004 | 14769887 |
