Phenotypic and Genotypic Antibiotic Resistance Features of S. aureus isolated from Milk and Cheese
Author(s): Shimaa Tawfeeq Abdallah Omara
The present paper analyses the antibiotic resistance features of the enterotoxigenic S. aureus that had isolated out of 205 milk and cheese samples. S. aureus strains showed resistance, mainly to oxacillin 71 (67.6%, 71 /105), penicillin 67 (63.8%, 67 /105), erythromycin 47 (44.8%, 47 /105), vancomycin 41 (39.1%, 41 /105) respectively. The multidrug-resistant S. aureus were detected in 54 (51.4%) S. aureus isolates. The isolated strains were screened for the presence of mecA, vanA, and ermC genes. The results showed that, 78 (74.3%, 78 /105), 50 (47.6%, 50 /105), and 38 (36.2%, 38 /105) of these strains were carrying for the mecA, ermC, vanA genes respectively. High level of MRSA contamination 52 (49.5%, 52/105) were detected and it was in details as follows; 31 (77.5%, 31/40), 5 (50%, 5/10), 10 (50%, 10/20), 5 (20%, 5/25), and 1(10%, 1/10) within th..
