WebThe mode of action of sulfonamides is the inhibition of tetrahydrofolic acid (THFA) synthesis. Many bacteria require p-aminobenzoic acid (PABA) as a precursor to their synthesis of the essential coenzyme tetrahydrofolic acid (THFA). PABA is a structural part of the THFA acid molecule. WebResistance to tetracyclines occurs when bacteria either develop proteins that prevent ribosomal binding by tetracyclines, or synthesize enzymes capable of inactivating tetracyclines. Widespread use of antibiotics and rapid microbial evolution have led to highly resistant bacterial strains. WebSulfa antibiotics target a specific enzyme that inhibits bacterial growth. Tetracycline antibiotics bind to bacterial ribosomes that are responsible for protein production and inhibit bacterial protein synthesis. Ciprofloxacin, one of the strongest antibiotics, attacks bacterial DNA replication while leaving human cellular DNA unaffected. 鳴神裁 好き嫌い
