Abstract

Background: Staphylococcus is a bacterium responsible for a wide range of diseases, from mild skin infections to lethal necrosis pneumonia. The aim of the present study was to determine the virulence factors among methicillin resistant and sensitive strains isolated from clinical specimens of children referred to the pediatric medical center and also to find out about their antibiotic resistance.Materials and Methods: In the present study, 100 strains of STAPHYLOCOCCUS AUREUS, susceptible and resistant to methicillin, were collected during one year. First, biochemical tests were performed to detect STAPHYLOCOCCUS AUREUS bacteria. Then, antibiotic susceptibility test was performed using antibiotic disks (MAST; England) according to CLSI guidelines. The presence of hlg, mecA, nuc, and pvl genes was investigated using PCR method and then sequenced.Results: A total of 30 samples (30%) were methicillin-resistant (MRSA) using the cefoxitin disk. Vancomycin was determined to be the most susceptible to antibiotics with 100% and penicillin had the highest resistance to antibiotics with 98%. The prevalence values for hlg, mecA, and pvl genes were 30%, 95%, and 6%, respectively.Conclusion: The present study showed that vancomycin and cotrimoxazole were the best effective antibiotics against MRSA strains.
