The study was done for described genotypically characterize of Staph. aureus isolated from the oral cavity of canary birds in Mosul city using polymerase chain reaction technique which was achieved by amplifying of the thermonuclear nuc gene specialized with Staph. aureus. Sixty birds were examined from variable ages of both sexes from different regions of Mosul city for the period of 1/5/2018-1/6/2019 was carried out. The results indicate that 35 samples gave Staph. aureus with the percentage of 58.4%. These isolates are positive for pigmentation of mannitol salt agar, hemolysis on blood agar, catalase and coagulase-positive, gram staining and oxidase negative. PCR technique indicate that all 35 isolates were positive for the nuc gene and produce amplicon of 166 bp. These results considered positive and it is very specific for bacterial isolates of staph aureus as well as may be used for strain isolation, characterization, and differentiation from other types of bacteria.
