was equal to 270 pb. In our study the isolates of S. aureus revealed increasing resistance against many antibiotics, such as Chloramphenicol while they appeared sensitive to other antibiotic like Vancomycin. 97.5% isolates of S. aureus were Chloramphenicol-resistant, 50.6% were Tetracycline-resistant and 3.7% were Vancomycin-resistant. In other reports the percentage
of Tetracycline-resistant S. aureus isolates was equal to 47.4% or 60.4% [23,24]. Most isolates of S. aureus were sensitive to Vancomycin and all isolates were sensitive to Rifampicin. The reports indicated that all clinical samples of S. aureus were resistant to Vancomycin [22,24], while the 3.85% of
