Abstract:
We cultured enterococci from urinary tract infections in Iranian hospitals. Seven different Enterococcus species (E. raffinosus, E. durans, E. hirae, E. avium, E. mundtii, E. faecium and E. faecalis) were found. Seven strains were vancomycin resistant, leading to an overall vancomycin resistance rate of 3.9%. The enterococcal infection rate was high and vancomycin-resistant enterococci incidence low. We report the first vanA-positive E. mundtii urinary tract infections.
Insights
This study identified seven Enterococcus species in Iranian urinary tract infections. While vancomycin resistance was low overall (3.9%), the first vanA-positive Enterococcus mundtii UTI was found.
Area of Science:
- Microbiology
- Infectious Diseases
- Clinical Diagnostics
Background:
- Enterococci are significant pathogens causing urinary tract infections (UTIs).
- Vancomycin resistance in enterococci is a growing global health concern.
- Surveillance of enterococcal species and antimicrobial resistance is crucial for effective treatment.
Observation:
- Enterococci were cultured from UTIs in Iranian hospitals.
- Seven distinct Enterococcus species were identified: E. raffinosus, E. durans, E. hirae, E. avium, E. mundtii, E. faecium, and E. faecalis.
- A low overall vancomycin resistance rate of 3.9% was observed.
Findings:
- Seven vancomycin-resistant enterococci (VRE) strains were detected.
- This study reports the first isolation of vanA-positive Enterococcus mundtii causing UTIs.
- Enterococcal infection rates were high, but the incidence of VRE was low.
Implications:
- The emergence of vanA-positive E. mundtii highlights the need for ongoing monitoring of antimicrobial resistance.
- Understanding the species distribution and resistance patterns of enterococci is vital for guiding empirical antibiotic therapy in UTIs.
- This finding contributes to the global understanding of VRE epidemiology and the potential for novel resistance mechanisms.
