(1) Their cidal (killing) or. Static (inhibitory) effect. They can be Bactericidal (inhibits the actinty) e.g. penicillin in bactericidal white Tetracycline is bactereostatic.
(2) Their spectrum of action i.e. the range of bacteria or other microorganisms that are affected by them. Antibiotics which are effective against a wide range of Gram – positive are broad spectrum antibiotics, those effective mainly against Gram – positive or gram negative bacteria are narrow spectrum antibiotics wherever those effective against only a single bacteria are limited spectrum antibiotics. e.g. Penicillin G is narrow spectrum while Arnpicillin in broad spectrum antibiotic.
How are antibiotics classified? Explain with example.

Antibiotics are classified on the basis of –
(1) Their cidal (killing) or. Static (inhibitory) effect. They can be Bactericidal (inhibits the actinty) e.g. penicillin in bactericidal white Tetracycline is bactereostatic.
