An updated phylogeny of the metallo-β-lactamases Draft genome sequence of extended-spectrum-β-lactamase-producing Escherichia coli

26 Sep 2019 The most common mechanism for drug resistance to β-lactam antibiotics is bacterial synthesis of β-lactamases (Hall et al, 2003). Many bacteria

At present, many specific detection methods and inhibitors of β‐lactamase have been developed and applied in clinical practice. In this Minireview, we describe the resistance mechanism of bacteria producing β‐lactamase and further summarize the fluorogenic probes, inhibitors of β‐lactamase, and their applications in the treatment of infectious diseases. Define lactamase. lactamase synonyms, lactamase pronunciation, lactamase translation, English dictionary definition of lactamase. n. Any of various enzymes that hydrolyze and inactivate beta-lactam antibiotics such as penicillin, found in many antibiotic-resistant bacteria. Beta-lactamase inhibitors are drugs that block the activity of certain beta-lactamases and are thus sometimes combined with beta-lactam antibiotics.

Induction of beta-lactamase synthesis is vital for the resistance of staphylococci to penicillins because the drug induces synthesis of the catalyst and is also hydrolysed by it.

An enzyme produced by many species of bacteria that disrupts the four-membered β-lactam ring of penicillin and cephalosporin groups of antibiotics, destroying their antimicrobial activity. The ability of an organism to produce a β-lactamase may be chromosomal and constitutive or a plasmid-associated acquired property.

Beta-lactamase inhibitors are drugs that block the activity of certain beta-lactamases and are thus sometimes combined with beta-lactam antibiotics. Examples include Clavulanate, sulbactam, tazobactam: These drugs block penicillinases but not AmpC or carbapenemases.

17 Feb 2015 Bacterial β-lactamases are members of an enzyme family (EC 3.5.2.6) that deactivate the effect of β-lactam antibiotics such as penicillins,

Although β-lactamase inhibitors have little antibiotic β-Lactams are the most widely used class of antibiotics. Since the discovery of benzylpenicillin in the 1920s, thousands of new penicillin derivatives and related β-lactam classes of cephalosporins, cephamycins, monobactams, and carbapenems have been discovered.
