Abstract: 

Background: Staphylococcus aureus is one of the most important pathogens of human beings all over the world and in all ages. The epidemiology and resistant pattern of this bacterium is not clear in Ilam hospitals, capital of Ilam province, Iran.
Methods: The antimicrobial patterns of S.aureus strains isolated from health-care –associated infections of different hospitalization wards including surgery and ICU have been investigated at Ilam Hospitals. Bacteria isolated from different samples in the microbiology laboratory of Ilam University of Medical sciences strains were identified under standard techniques.
Results: Antibiotic susceptibility and Minimum Inhibitory Concentrations was done by E-test and routine antibiotics. A total of 30 S.aureus isolates were isolated from urinary (12; 40%), wound (10; 33.3%), lung (5; 16.6%), and burn (3; 10%) infections. All of the isolates were susceptible to vancomycin and linezolide and 10% of strains were methicillin resistant. Resistance percent for other drugs were as follow: piperacillin /tazobactam 4 (13.3%), ceftriaxone 11 (36.3%), amoxicillin 13 (43.4%), amikacin (3.3%), ceftazidime 2 (6.6%), tobramycin 3 (9.9%), tetracycline 11 (36.3%), gentamicin 3 (9.9%). Five isolates had MICs
³1.5 mg/ml against vancomycin. Conclusion: Although about 10% of our isolates were resistant to methicillin, and 100% were susceptible to vancomycin and linezolide, but in some of the isolates we encountered a rise in MICs against vancomycin. This point emphasizes the implementation of related control measures in hospitals for further control of the treatment of resistant infections.
