Healthcare workers (HCWs) are proposed as the potential source of transmission of Staphylococcus aureus to hospitalized patients, especially in burn units. This study aimed to investigate S. aureus from burn wound infections and those from the nose of HCWs in terms of antibiotic resistance, the presence of Panton-Valentine leucocidin-encoding gene (pvl) and the arginine catabolic mobile element (ACME), and the ability for biofilm formation.

Article Synopsis
  • The study aimed to investigate how genes related to erythromycin and tetracycline resistance are distributed among Enterococcus isolates and their link to resistance patterns.
  • Eighty-six E. faecalis and 26 E. faecium samples were collected from hospitals, and the researchers tested the minimum inhibitory concentrations of the two antibiotics while examining specific resistance genes.
  • Results showed that 64% of the isolates were resistant, with high prevalence of specific resistance genes identified, indicating that alterations in ribosomal structures were more common than efflux mechanisms, particularly for erythromycin resistance.

Introduction: is one of the most common pathogens in urinary tract infections (UTIs). Fluoroquinolones have been frequently used to treat UTIs, and the emergence of fluoroquinolone-resistant strains has recently been reported in several countries. This study aimed to elucidate the mechanisms involved in fluoroquinolone resistance in clinical isolates by analyzing mutations in quinolone- resistance-determining regions (QRDRs) of A and C and investigating the role of some efflux pumps.
