Antibiotics can be divided into two main groups. One is to inhibit the growth of pathogens, and the other is to kill pathogens directly. Can be used to treat most bacterial infectious diseases.

There are 4 main mechanisms of antibiotic bactericidal action:

1. interference with protein synthesis: interference with protein synthesis means that the enzymes necessary for cell survival can not be synthesized. Antibiotics that interfere with protein synthesis can be found to be antibiotics, aminoglycosides, aminoglycosides, tetracyclines, and chloramphenicol.

The synthesis of 2. inhibition of cell wall: can inhibit cell wall synthesis leads to bacterial cell rupture and death, in this way the effect of antimicrobial agents including penicillin and cephalosporins, mammalian cells without cell wall, not affected by these drugs.

3. inhibits nucleic acid transcription and replication: inhibits nucleic acid function, prevents cell division and / or synthesis of desired enzymes. Antibiotics that act in this manner include naphthalene acid and two chloro acridine.

4. interact with cell membranes: some antibiotics interact with cell membranes to affect membrane permeability, which has a lethal effect on cells. The antibiotics that act in this way are polymyxin and colistin.
