While celebrated as beneficial probiotics, many *Lactobacillus* species are intrinsically resistant to several common antibiotics, including vancomycin. Understanding **what antibiotic kills Lactobacillus** requires knowledge of bacterial sensitivity, as the effect depends heavily on the specific strain and the antibiotic class used.

Bacitracin is a polypeptide antibiotic, first discovered in 1943, that exerts its antibacterial effect by targeting bacterial cell wall synthesis. It has long been recognized for its potent activity against many types of Gram-positive bacteria, which is the key to understanding **what bacteria are bacitracin sensitive to**.
