Abstract A total of 120 raw milk samples were collected from different animal farms at Giza governorate. Each sample was divided into two parts; one part was kept at room temperature and the other part was kept at refrigeration temperature. All the parts were subjected for bacteriological examination for isolation and identification of S. aureus by catalase, coagulase, thermonuclease and Voges-Proskauer tests. 31 out of 120 and 29 out of 120 raw milk samples kept at room and refrigeration temperature contained S. aureus. 26 isolates were underwent RPLA technique for detection of enterotoxigenic S. aureus (11 isolates). Enterotoxigenic S. aureus were cultured in pasteurized milk and incubated at room and refrigeration temperatures for detection of enterotoxins production. |
