What are antibiotics? How is it useful in treatment of disease? Which type of disease are treated by antibiotics?
Dear student, Antibiotics are the medicines which inhibit the growth of bacteria and kill them. Antibiotics act by blocking certain biochemical pathways which are essential for the survival of bacteria like cell wall formation, protein synthesis etc. For example: Penicillin is an antibiotic. It blocks the formation of cell wall in bacteria, which makes bacteria weak and ultimately results in death of bacteria. Antibiotics treat bacterial diseases. Thanks and regards
