The first section of common antibacterial antibacterial drugs, including antibiotics, sulfonamides and furans and other synthetic antibacterial drugs. The figure below outlines the antibacterial mechanism of these drugs. 1. Inhibit cell wall biosynthesis (penicillin, cephalosporin) 2. Affect cytoplastic membrane permeability (polymyxin, nystatin) 3. Affect acid synthesis (sulfa etc.) 4. Affect protein synthesis (chlorine Antibiotic antibiotics (formerly known as antibiotics) is from Gram-positive bacteria and streptococci and other microbial culture fluid In a class of drugs that kill or inhibit other microorganisms. The main role of Gram-positive bacteria antibiotics are:
