Quantitative polymerase chain reaction for Porcine circovirus-2 in swine feces in a Porcine circovirus disease-affected commercial herd and a nonaffected commercial herd
Kathleen A. McIntosh, John C.S. Harding, Sarah Parker, Steven Krakowka, Gordon Allan, John A. Ellis
This study examined if pigs in a Porcine circovirus disease (PCVD)-affected herd (n = 100) had shed more Porcine circovirus-2 (PCV-2) in their feces than pigs in a PCVD-nonaffected herd (n = 101), and if differences in shedding among production stages within and between the herds existed. The PCV-2 shedding was quantified by real-time polymerase chain reaction. The highest median PCV-2 shedding was found in the nursery of the PCVD-affected herd and in the grower of the PCVD-nonaffected herd. The PCV-2 shedding was significantly higher in earlier stages (newly weaned, nursery, and pregrower) in the PCVD-affected herd (Wilcoxon rank sum; P < 0.001) compared with the PCVD-nonaffected herd. Porcine circovirus-2 DNA was not detected in a significant proportion of lactating sows (parity = 3) in the PCVD-nonaffected herd (Fisher’s exact test; P = 0.001). The results of this study suggest there may be an association between the presence of PCV-2 in the feces of lactating sows and increased PCV-2 shedding in younger pigs.
