Analysis of the Zinc Finger Domain of TnpA a DNA Targeting Protein Encoded by Mobilizable Transposon Tn4555 2011 688479 The mobilizable transposon Tn4555 found in Bacteroides spp. is an important antibiotic resistance element encoding a broad spectrum beta-lactamase. Tn4555 is mobilized by conjugative transposons such as CTn341 which can transfer the transposon to a w...
Cloning and characterization of the endogenous cephalosporinase gene cepA from Bacteroides fragilis reveals a new subgroup of Ambler class A beta-lactamases. 2011 688479 Bacteroides frgiglis CS30 is a clinical isolate resistant to high concentrations of benzylpenicillin and cephaloridine but not to cephamycin or penem antibiotics. beta-Lactam resistance is mediated by a chromosomally encoded cephalosporinase produced...
Genetic and biochemical analysis of a novel Ambler class A β-Lactamase responsible for cefoxitin resistance in Bacteroides species. 2011 688479 A clinical isolate of Bacteroides vulgatus was resistant to tetracycline clindamycin ampicillin cephaloridine efoxitin and other 13-lactam antibiotics except imipenem. 13-Lactam resistance was mediated by a membraneassociated lavulanate-sensitive cep...
Identification of a circular intermediate in the transfer and transposition of Tn4555 a mobilizable transposon from Bacteroides spp. 2011 688479 Transmissible cefoxitin (FX) resistance in Bacteroides vulgatus CLA341 was associated with the 12.5-kb obilizable transposon Tn4555 which encoded the 13-lactamase gene cfxA. Transfer occurred by a onjugation-like mechanism was stimulated by growth of...
Molecular and genetic analysis of the Bacteroides uniformis cephalosporinase gene cblA encoding the species-specific beta-lactamase. 2011 688479 The gene cbl encoding the species-specific clavulanate-susceptible endogenous cephalosporinase was cloned from Bacteroides uniforinis WAL-7088. The nucleotide sequence was determined and the cbl structural gene was found to be 891 nucleotides with a ...
