Use of a polymerase chain reaction assay and an ELISA to monitor porcine circovirus type 2 infection in pigs from farms with and without post-weaning multisystemic wasting syndrome.
AJVR, Vol. 65, N?1, 2004, 88-92
A total of 495 pigs were included in this study, 236 of them were from PMWS-affected herds while the remaining ones were from farms without PMWS. Serum samples were submitted to ELISA detection for antibodies to PCV2 and both serum samples and nasal swabs were submitted to PCR analysis for PCV2 DNA. Interestingly, viremia and serum antibodies to PCV2 were detected in both PMWS-affected and non-affected farms confirming a high prevalence of PCV2 infection in swine herds and supporting the idea that full expression of PMWS requires other factors than infection with PCV2.
