Abstract

In this study, a total of 209 isolates were isolated from raw calf meat (minced), chicken drumsticks, raw milk, ice cream and white cheese samples. One hundred and seventy-five (83.7 %) coagulase-negative Staphylococci (CNS) and 34 (16.3%) coagulase-positive staphylococci (CPS) were isolated from these samples. The majority of Staphylococcusisolates showed biofilm formation (75.1%) and slime formation (68.4%). The frequency of positive protease and lipase production for Staphylococcus aureus isolates were 23.5 and 11.8%, respectively. Proteolytic and lipolytic activitiy were not found in the otherStaphylococcus species. The overall antimicrobial susceptibility profiles revealed that the highest percentage of resistance was detected for ampicillin (33.8%), tetracycline (26.3%), erythromycin (20.6%), methicillin (17.2%) and gentamicin (12.4%). The susceptibility to vancomycin, chloramphenicol, amikacin and clindamycin were 100% for all isolates.
