Abstract: The 946 serum samples were tested for antibodies against three porcine infectious agents in this study. The results showed the presence of antibodies to Salmonella in 53.70% of samples (508/946) to Trichinella in 3.81% of samples (36/946) to Yersinia in 65.33% of samples (618/946) and relevant herd positive rates were 54.55% (30/55), 7.27% (4/55) and 67.27% (37/55) correspondingly. Scaled farms or total farms (scaled and individual) displayed lower seroprevalence for Trichinella of 1.88% (10/532) or 2.44% (16/656) when compared to 6.90% (20/290) for abattoirs (p≤0.01) and individual farms showed lower seroprevalence for Yersinia of 37.10% (46/124) when compared to 71.80% (382/532) for scaled farms and 65.52% (190/290) for abattoirs (p≤0.01). These demonstrated specific circulation of porcine Salmonella, Trichinella and Yersinia among pigs in some regions of Guizhou Province.
