Plasmid-mediated and inducible cephalosporinase DHA-2 from Klebsiella pneumoniae.
A Klebsiella pneumoniae strain resistant to cefoxitin and oxyimino-cephalosporins was cultured from a child hospitalized in Paris, France, in 1992. This isolate harboured a beta-lactamase gene located on an approximately 200 kb non-self-transferable plasmid. The beta-lactamase identified, DHA-2, shared 99% amino acid identity with the AmpC enzyme of Morganella morganii. DHA-2 was a point-mutant...
متن کاملNucleotide sequence of a plasmid-mediated cephalosporinase gene (blaLAT-1) found in Klebsiella pneumoniae.
The nucleotide sequence of the gene encoding a novel cephalosporinase (LAT-1), carried by a non-self-transferable plasmid from Klebsiella pneumoniae, has been determined. It was found that the sequence shares a high degree of homology with the Citrobacter freundii OS60 ampC structural gene.
متن کاملPrevalence of Plasmid-Mediated Quinolones Resistance among Klebsiella pneumoniae Strains Isolated from Hospitals in Borujerd, Iran
ABSTRACT Background and Objective: Klebsiella pneumoniae is one of the most common causes of bacterial infections. Presence of plasmid-mediated quinolone resistance genes causes low level of resistance in K. pneumoniae. This study investigated the prevalence of resistance to quinolones and fluoroquinolones, and the frequency of qnrA, qnrB and qnrS genes amo...
متن کاملPlasmid- mediated cefotaxime and ceftizoximd resistance in Ten strains of klebsiella pneumoniae isolated from hospitals in Kerman,Iran
Klebsiella pneumonia is a gram negative bacillus of which it's resistant strains are a common source of nosocomial infections . The goal of this study is determination of drug sensitivity of these resistant strains, and study of causes involved in the resistant especially the presence of plasmid. Ten different strains of klebsiella pneumoniae were isolated from clinical specimens collected from...
متن کاملPlasmid-mediated, carbapenem-hydrolysing beta-lactamase, KPC-2, in Klebsiella pneumoniae isolates.
Four isolates of Klebsiella pneumoniae obtained from patients at a Maryland medical centre exhibited reduced susceptibility to carbapenems and were found to produce the novel, class A, plasmid-mediated, carbapenem-hydrolysing enzyme, KPC-2. This enzyme has 99% identity with the plasmid-mediated, carbapenem-hydrolysing enzyme KPC-1, reported previously in a North Carolina K. pneumoniae isolate. ...
