This study aimed to compare the occurrence of potentially nasal Staphylococcus aureus (S. aureus) of both female medical students and non-medical students at Al-Jouf University and its resistance & sensitivity of methicillin antibiotic. A cross-sectional study was conducted on 30 females’ volunteers. Students including 15 medical students and 15 non-medical students. Specimens were taken from the subjects by a sterile moistened swab, which inserted into each nostril in turn, to a depth of approximately 1 cm, and rotated five times. Then the specimens were subjected to bacteriological examination, isolated S. aureus were subjected for further identification by biochemical tests. Then methicillin antibiotic test sensitivity and resistant were performed on isolates. We found that S. aureus in both samples medical and non-medical with 60% ,and methicillin resistant S. aureus in each samples medical and non-medical with 66.7% as Statistical analysis demonstrated.

Introduction: Staphylococcus aureus is known to be a major cause of skin and soft tissue infections, pneumonia and invasive diseases. In this study, attempts were made to examine the prevalence of tsst-1, eta, etb, and luk-PV genes among methicillin-resistant S. aureus (MRSA) isolated from children in Tehran. Methodology: In the present cross-sectional study, a total of 100 MRSA were isolated from children who were referred to a pediatric hospital during 11-month period of September 2014 to August 2015. Isolates were identified using biochemical tests and then, using PCR, the isolates were tested for the presence of mecA, tsst-1, eta, etb, and luk-PV genes. Susceptibility of isolates to cefoxitin, penicillin, erythromycin, clindamycin, gentamicin, rifampin, minocycline, co-trimoxazole, linezolid, and vancomycin were evaluated using standard methods. Results: It was found that the MRSA isolates had the greatest resistance to clindamycin (72%) and erythromycin (59%), while the lowest rates of resistance were observed to be related to minocycline (6%) and rifampin (12%). All of isolates were sensitive to vancomycin and linezolid. The mecA gene was detected in all the isolates. Moreover, luk-PV and tsst-1 were detected in 18% and 17% of the isolates, respectively. None of the isolates harbored eta and etb genes. Conclusions: Our data provide specifications about the toxin production status of S. aureus isolates from pediatric children. The current study showed increased resistance to different antibiotics in S. aureus isolates. Therefore, to prevent multi-resistance to other antibiotic classes, it is essential to withhold prescriptions and stop unessential use of available antibiotics.
