Action mechanisms of antibiotics 1. Inhibit synthesis of bacterial cell walls 2. Affect permeability of cell membrane and lead to leakage of intracellular compounds 3. Inhibit protein synthesis 4. Affect bacterial nucleic acid metabolism 5. Block essential enzymes of folate metabolism1. Inhibit synthesis of bacterial cell walls 2.
