Out of 485 samples only 46 (9.48 %) were identified as coagulase Positive staphylococci (Staph aureus), In Hospital wards 5(10.9%) Staph aureus were identified, 4 in Al-Basra Teaching Hospital and one in Al-Sadder Teaching Hospital. (P>0.05)MecA genes appeared in all MRSA isolates while Hld gene appeared at 61.5% (24/39); followed by Sea gene at 41% (16/39) and Tst gene at 15.4% (6/39), the lowest presence in Seb genes, it was 10.3% (4/39).The distribution of genes in MRSA isolates showed that there were significant differences in the distribution of Seb gene in different samples, where the P ...

Hld gene also showed significant differences of distribution in different samples where it was found in 100% MRSA in both of hospital wards and Operating Theaters, 80% in patient nose, 71.4% in H.C.Ws nose, 60% in wound MRSA and 3.3% in patient skin swab MRSA. Negative Hld gene showed in H.C.Ws hand MRSA.
