Abstract

Porcine circovirus type 2 (PCV2) and porcine reproductive and respiratory syndrome virus (PRRSV) are known as significant immunosuppressive viruses in pigs. In this study, we investigated the correlation of PCV2 and PRRSV in enteric lesions of porcine salmonellosis. A total of 64 cases were classified into four pig groups as group A (24 cases, S. Typhimurium), group B (11 cases, S. Typhimurium+PCV2), group C (16 cases, S. Typhimurium+PRRSV) and group D (13 cases, S. Typhimurium+PCV2+PRRSV). Comparing with group A, ulcerative enteritis in large intestine was little more prevalent in the PCV2 infected pigs in group B and D. And lymphoid depletion in gut-associated lymphatic tissue (GALT) of large intestine was also detected in PCV2 positive group B (36.4%) and D (30.8%). According to the results of immunohistochemistry (IHC), PCV2 antigens (83.3%) were more prevalently distributed in the intestinal lesions of porcine salmonellosis than PRRSV antigens (10.3%). PCV2 were also detected in the lymphoid depleted GALT of the large intestine from 7 of the 8 pigs (87.5%), but PRRSV were not found in all cases. It may explain that PCV2 can play a certain immunological role to enhance secondary bacterial infection in porcine alimentary tracts.
