Heterogeneous hydrolytic features for OXA-48-like β-lactamases.
OBJECTIVES Carbapenem-hydrolysing class D β-lactamases of the OXA-48 type are increasingly reported from Enterobacteriaceae. β-Lactamase OXA-48 hydrolyses penicillins very efficiently, but carbapenems only weakly and spares broad-spectrum cephalosporins. Recently, diverse OXA-48-like β-lactamases have been identified worldwide (OXA-162, OXA-181, OXA-163, OXA-204 and OXA-232). They differ by few...

متن کاملOXA (beta)-lactamases in Acinetobacter: the story so far.
The emergence of carbapenem resistance in Acinetobacter baumannii has become a global concern since these beta-lactams are often the only effective treatment left against many multiresistant strains. A recent development has been the discovery of a novel group of narrow-spectrum OXA beta-lactamases in carbapenem-resistant strains, some of which have acquired the ability to hydrolyse the carbape...

متن کاملAcquired Class D β-Lactamases.
The Class D β-lactamases have emerged as a prominent resistance mechanism against β-lactam antibiotics that previously had efficacy against infections caused by pathogenic bacteria, especially by Acinetobacter baumannii and the Enterobacteriaceae. The phenotypic and structural characteristics of these enzymes correlate to activities that are classified either as a narrow spectrum, an extended s...
