Abstract

Surgical site infection is one of the common types of hospital infections; it significantly limits the effectiveness of surgical interventions, increases the cost of treatment, and prolongs the duration of treatment. Staphylococcus aureus (S. aureus) is currently the most common cause of infection in hospitalized patients and it is also the most antibiotic-resistant bacteria. In this study, a total of 442 specimens from surgical patients treated at 175 Military Hospital including fluid, pus was collected and analyzed. In which, the infection rate caused by S. aureus bacteria accounts for 15.2%. The isolated S. aureus were resistant to 7 types of antibiotics, namely: penicillin100%; oxacillin 76.1%; erythromycin 65.7%; cefalexin 67.7%; getamycin 35.8%; ciprofloxacin 28.3%, and vancomycin 7.5%. No sequence variation in mecA genes of S. aureus in this study was found; however, there was a difference in mecA gene sequence among samples in this study compared to mecA gene of S. aureus of different countries around the world. The results of this study could be beneficial for further studies of the relationship between mecA gene sequence and antibiotic resistance of S. aureus bacteria.
