Staphylococcus aureus is an opportunist that causes systemic infections in the human being body. This organism increases its resistance to many categories of antibiotics more resistant. Given this fact, a total of one hundred seventy-two (N = 172) samples, and the total number of positive samples for Staphylococcus aureus was seventy-seven (N = 77) samples. The number of positive which included 30 (38.39 %) pus samples, 27 (35.0 %) urine samples, 11 (14.28 %) of nasal swabs, and 9 (11.68 %) blood samples. These isolates were identified according to culture, microscopic examination, biochemical tests, and APIstaph system identification kits. The results showed 34 (44.15 %) of isolated S. aureus were MRSA strain. regarding of the molecular identification of MRSA the results showed mecA and Insertion sequence (IS431) is present in all cases in percent 100 % (34/34), (IS127) were 100 %, (34/34). Other gens were gene of ccrC 20/34 (57.14 %) and ccrA2-B gene 6/34 (17.64 %).
