The opportunistic pathogen Enterococcus faecium colonizes humans and a wide range of animals, endures numerous stresses, resists antibiotic treatment and stubbornly persists in clinical environments. The widespread application of antibiotics in hospitals and agriculture has contributed to the emergence of vancomycin-resistant E. faecium, which causes many hospital-acquired infections.

Article Synopsis
  • * The rising issue of antimicrobial resistance emphasizes the need for new therapeutic targets, making it crucial to understand how pathogens like a specific bacterium associated with UTIs survive in the urinary tract.
  • * This study involved creating high-quality genomic data of bacteria isolated from postmenopausal women's urine to analyze genetic factors that may contribute to their survival in the urinary tract.

Unlabelled: is the leading Gram-positive bacterial species implicated in urinary tract infection (UTI). An opportunistic pathogen, is a commensal of the human gastrointestinal tract (GIT) and its presence in the GIT is a predisposing factor for UTI. The mechanisms by which colonizes and survives in the urinary tract (UT) are poorly understood, especially in uncomplicated or recurrent UTI.

The human microbiota harbors diverse bacterial and bacteriophage (phage) communities. Bacteria evolve to overcome phage infection, thereby driving phage evolution to counter bacterial resistance. Understanding how phages select for genetic alterations in medically relevant bacteria is important as phages become established biologics for the treatment of multidrug-resistant (MDR) bacterial infections.

and are Gram-positive bacteria that normally inhabit the human gastrointestinal tract. They are also opportunistic pathogens and can cause nosocomial infection outbreaks. To prevent the spread of nosocomial infections, hospitals may rely on screening methods to identify patients colonized with multidrug-resistant organisms including vancomycin-resistant enterococci (VRE).
