Pronunciation of beta-lactamase and its etymology. a ) Induction of staphylococcal β-lactamase synthesis in the presence of the β- lactam antibiotic penicillin.

Beta lactamase

2.6) produced by bacteria that provide multi-resistance to β-lactam antibiotics such as penicillins, cephalosporins, cephamycins, and carbapenems (ertapenem), although carbapenems are relatively resistant to beta-lactamase. Beta-lactamases are an important group of bacterial enzymes, which preferentially cleave the beta-lactam ring of penicillins, cephalosporins, or other medically important beta-lactam antibiotics (Fig. 1). be·ta-lac·ta·mase.

The bacteria then become resistant to the antibiotics. This means stronger antibiotics must be used to kill the bacteria. Various bacteria produce a class of enzymes called beta-lactamases, which may be mediated by genes on plasmids or chromosomes.

Beta-lactamase enzymes are produced by certain strains of the following bacteria: Bacteroides species, Enterococcus species, Hemophilus influenzae, Moraxella catarrhalis, Neisseria gonorrhoeae, and Staphylococcus species, either constitutively or on exposure to antimicrobials. Beta-lactamase inhibitors are drugs that block the activity of certain beta-lactamases and are thus sometimes combined with beta-lactam antibiotics. Examples include Examples include Clavulanate, sulbactam, tazobactam: These drugs block penicillinases but not AmpC or carbapenemases. Extended-spectrum beta-lactamases, or ESBLs, are enzymes produced by certain types of bacteria.

β-laktamas eller beta-laktamas är ett enzym som bryter ner beta-laktamantibiotika som penicilliner, cefalosporiner och karbapenemer. De verkar genom att bryta den reaktiva beta-laktamasringen hos dessa antibiotika. Det har upptäckts mer än 850 olika beta-laktamaser, alla härstammande ifrån naturligt förekommande beta-laktamaser.
