How Does pathogenic bacteria acquire ‘bullet proof vest’ against our magic-bullet-’Penicillins’ ?
Antibiotics like penicillin are often called “magic bullets” because they target structures unique to bacteria, such as the peptidoglycan layer in their cell walls. These antibiotics block the enzymes responsible for forming peptide cross-links in peptidoglycans, weakening the bacterial wall and ultimately killing the bacteria. Penicillins and their synthetic derivatives contain a special structure called […]
