Twelve strains of Staphylococcus aureus isolated from blood, wound and middle ear infections were tested against (20) kinds of antibiotics by disk diffusion method .The strains showed absolute resistance to Penecillin,Cloxacillin and Ceftazidime, while their resistance percentages to Ampicillin, Amoxicillin and Vancomycin were (91.7%,75%,33.3%) respectively. On the other hand the isolates showed absolute sensitivity to Cefuroxime , Amikacin and Chloramphenicol ,to Ciprofloxacin and Cephlothin
