Objective Staphylococcus aureus is an extra-ordinarily versatile pathogen that causes a wide variety of infections in humans and animals, capable of causing superficial lesions and systemic infections. The aim of this study was to detect mecA gene in smokers of cigarette and hookah. Results Forty-one isolates (41%) were identified as S. aureus by traditional culture methods. non-smokers, nasal carriers of S. aureus were 16 (39%) while 25 (60%) among smokers (P = 0.103). Of the overall 25 smoker

MRSA was 1 (2.4%) in non-smokers and 3 (7.2%) in smokers, 2 in cigarettes and 1 in hookah (P = 0.009). Only 38 isolates were confirmed as S. aureus by PCR (mecA gene). In non-smokers group mecA were 6 (15.8%) positive and 8 (21%) negative, while in smokers were 16 (42.3%) positive and 8 (20.9%) negative isolates (P = 0.187). From hookah 12 mecA positive and 4 from cigarette (P = 0.647). The correlation of MRSA and using of antibiotic during last 6 months indicates significant (P = 0.031).
