The mechanism of action of the cephalosporins is that of beta-lactam antibiotics. For susceptibility testing, cephalothin is the class drug for group 1 and 2, first-generation, cephalosporins. For groups 3鈥 7, second- to fourth-generation cephalosporins, there is no class representative. The ...
beta-Lactam antibiotics share a common structure and mechanism of action, although they differ in their spectrum of antimicrobial activity and utility in treating different infections. The current classes include the penicillins, the penicillinase-resistant penicillins, the extended- spectrum penicillins,...
