Abstract
In a slaughterhouse, S. aureuswas isolated from 27% and 2% of the surface samples of washed swine and bovine carcasses, respectively, and from 4.3% and 1.4% of the swine and bovine intestinal contents, respectively. The isolates were of coagulase type VII from bovine carcasses, types I and IV from swine intestinal contents, and type VI from bovine intestinal contents. The organism was isolated from 5.7% of swine septicemic cases and all the isolates were of coagulase type IV. ByS. aureusslide latex agglutination test 20% of the isolates were negative. No isolates produced enterotoxins nor toxin-1, and all the isolates were sensitive to methicillin.
