Recent studies have revealed that antibiotic-induced dysbiosis can deplete beneficial *Lactobacillus* species in the gut, leading to significant health consequences. Understanding **which antibiotic kills Lactobacillus** is complex because the susceptibility varies widely by species and class of antibiotic.

While fosfomycin is a reliable option for uncomplicated urinary tract infections (UTIs), its effectiveness is limited by a range of bacteria that are intrinsically resistant. Understanding what bacteria does fosfomycin not cover is critical for selecting the appropriate antibiotic and ensuring successful treatment, especially in an era of rising antimicrobial resistance.

Most anaerobic bacteria are intrinsically resistant to aminoglycoside antimicrobial agents due to their lack of oxygen-dependent transport systems required for drug uptake. This poses significant challenges for treatment, highlighting the critical need to identify **what bacteria are resistant to aminoglycosides** before prescribing.

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.
