Abstract
Introduction: The newly-launched strain of the Staphylococcus aureus, methicillin-resistant S. aureus, is considered the most emerging bacterium in-hospital infections globally.
Objectives: The current research focused on the prevalence and virulence features of methicillin-resistant S. aureus (MRSA) bacteria recovered from urinary tract infections (UTIs) cases.
Patients and Methods: A total of 710 urine specimens were taken from hospitalized patients who suffered from UTIs. S. aureus was recovered from urine specimens using the microbial culture. S. aureus antimicrobial susceptibility was assessed toward oxacillin and cefoxitin antimicrobial disk to determine the MRSA strains. The polymerase chain reaction (PCR) assessed the distribution of antimicrobial resistance encoding genes. S. aureus antimicrobial resistance was evaluated by disk diffusion.
Results: Fifty-five out of 710 (7.7%) urine specimens were positive for the MRSA bacteria. The uppermost antibiotic resistance was obtained against penicillin (100%), ceftaroline (100%), gentamicin (87.2%), erythromycin (76.3%), and ciprofloxacin (69.0%). BlaZ (100%) and tetK (85.4%) had the higher frequency amid examined antimicrobial resistance-encoding genes.
Conclusion: The high prevalence of MRSA isolates harboring antimicrobial resistance-encoding genes in the UTIs suggests that diseases caused by them need more expansion healthcare monitoring with essential demand for novel antimicrobials.
