A beta-lactam (β-lactam) ring is a four-membered lactam. A lactam is a cyclic amide, and beta-lactams are named so because the nitrogen atom is attached...

β-lactam antibiotics (beta-lactam antibiotics) are antibiotics that contain a beta-lactam ring in their chemical structure. This includes penicillin derivatives...

Beta-lactamases (β-lactamases) are enzymes (EC 3.5.2.6) produced by bacteria that provide multi-resistance to beta-lactam antibiotics such as penicillins...

Capnocytophaga spp. are usually susceptible to antibiotics, but the emergence of beta-lactam-resistant strains has been observed as early as 1980. Genes for antibiotic...

This is a list of common β-lactam antibiotics—both administered drugs and those not in clinical use—organized by structural class. Antibiotics are listed...

Similar to penicillins and cephalosporins, carbapenems are members of the beta-lactam antibiotics drug class, which kill bacteria by binding to penicillin-binding...
