PCR and qPCR for detection of Porcine Circovirus type 2 (PCV2) in captive white-lipped (Tayassu pecari) and collared (Tayassu tajacu) peccaries from Southern Brazil
Porcine virus type 2 (PCV2) is an emergent virus found in commercial pig farms and may cause clinical or subclinical infection. Wild pigs such as collared peccary (Tayassu tajacu) and white-lipped peccary (Tayassu pecari) may also be infected by PCV2. Accordingly, the aim of this study was to molecu...

Porcine virus type 2 (PCV2) is an emergent virus found in commercial pig farms and may cause clinical or subclinical infection. Wild pigs such as collared peccary (Tayassu tajacu) and white-lipped peccary (Tayassu pecari) may also be infected by PCV2. Accordingly, the aim of this study was to molecularly identify PCV2 in whole blood samples of captive peccaries (16 collared and 6 white-lipped) by conventional and quantitative PCR (qPCR). Although the housekeeping gene (?-actin) DNA was successfully amplified, all 22 peccaries tested negative for PCV2 by both molecular methods.
