Incidence of Vancomycin-Resistant Staphylococcus aureus Strains among Patients with Urinary Tract Infections

There has been a substantial rise in the number of vancomycin-resistant Staphylococcus aureus (VRSA) strains during the last several years. The proportion of vancomycin-resistant strains among isolated S. aureus has risen steadily in recent years, with the first spike occurring in critical care units and thereafter in general hospital wards. S. aureus isolates from urinary tract infection patients were studied for their prevalence and antibiotic resistance. From 292 urine samples, 103 bacterial strains (35.3%) were identified as S. aureus. Various antibiotics were used to test the isolates' antibacterial resistance profiles. Antibiotic resistance to erythromycin was found in most bacterial isolates, whereas tobramycin antibiotic sensitivity was found in most of them. Vancomycin resistance was found in 23 of all S. aureus isolates in this study. Analysis for beta-lactamase found that 71% of S. aureus isolates were positive in all isolates. There was a single plasmid with a molecular weight of 39.306 Kbp in five selected VRSA isolates that was subjected to plasmid analysis. There was evidence of vancomycin resistance among the S. aureus isolates collected from UTI patients in this investigation. This vancomycin resistance pretenses a challenge in the treatment of S. aureus infections and the need to precisely recognize persons who require last-resort medication such as tobramycin.
