According to a 2013 CDC report, vancomycin-resistant Enterococcus was categorized as a “serious threat,” underscoring that not all bacteria are susceptible to this powerful antibiotic. Understanding what bacteria does vancomycin not treat is critical for effective infection management and combating the rise of antimicrobial resistance. This guide delves into the specific types of pathogens that evade vancomycin's effects, explaining the underlying pharmacological and biological reasons.
