The Bacteroides mobilizable transposon Tn4555 integrates by a site-specific recombination mechanism similar to that of the gram-positive bacterial element Tn916
(East Carolina University, 1997-04)
The Bacteroides mobilizable transposon Tn4555 is a 12.2-kb molecule that encodes resistance to cefoxitin. Conjugal transposition is hypothesized to occur via a circular intermediate and is stimulated by coresident tetracycline ...
The Transfer Origin for Bacteroides Mobilizable Transposon Tn4555 Is Related to a Plasmid Family from Gram-Positive Bacteria
(East Carolina University, 1998-01)
Conjugal transfer of Bacteroides mobilizable transposon Tn4555 was examined with an Escherichia coli-based assay system. It was shown that mobilization required the cis-acting oriTTn region and that the Tn4555 mobATn gene ...
Identification of a circular intermediate in the transfer and transposition of Tn4555, a mobilizable transposon from Bacteroides spp.
(East Carolina University, 1993-05)
Transmissible cefoxitin (FX) resistance in Bacteroides vulgatus CLA341 was associated with the 12.5-kb,
mobilizable transposon, Tn4555, which encoded the 13-lactamase gene cfxA. Transfer occurred by a
conjugation-like ...
Cloning and characterization of the endogenous cephalosporinase gene, cepA, from Bacteroides fragilis reveals a new subgroup of Ambler class A beta-lactamases.
(East Carolina University, 1993-11)
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 ...
Molecular and genetic analysis of the Bacteroides uniformis cephalosporinase gene, cblA, encoding the species-specific beta-lactamase.
(East Carolina University, 1994-08)
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 ...
Genetic and biochemical analysis of a novel Ambler class A β-Lactamase responsible for cefoxitin resistance in Bacteroides species.
(East Carolina University, 1993-05)
A clinical isolate of Bacteroides vulgatus was resistant to tetracycline, clindamycin, ampicillin, cephaloridine,
cefoxitin, and other 13-lactam antibiotics except imipenem. 13-Lactam resistance was mediated by a ...
