This study was conducted to isolate and diagnose Staphylococcus aureus causing infections of wounds and burns in the city of Samarra, and a sensitivity test for (12) antibiotics was conducted. Erythromycin, Ceftriaxone, Aztreonam and complete sensitivity to the antibiotics Amikacin, Ciprofloxacin, Imepineme, Levofloxacin and varying resistance to the rest of the antibiotics, and some virulence factors have been investigated for these bacterial isolates Understudy, where the current study included the collection of 110 swabs from patients hospitalized in Samarra General Hospital and some private medical clinics in the city of Samarra from patients with infections of wounds and burns, for both sexes, and at different ages. 16 Isolation of 14.54% of these bacteria from patients in the consulting department, emergency ward, operating ward, internal ward, gynecology and maternity ward, children's ward, and dressing division, in the hospital where Staphylococcus aureus bacteria were produced. Factors of induced virulence The results are as follows:- DNase at 81.25%, hemolysin at 87.5%, Coagulase at 100%, lecithinase & lipase at 62.5%, and urease at 81.25 %
