Insertional activation of cepA leads to high-level beta-lactamase expression in Bacteroides fragilis clinical isolates.
(East Carolina University, 1994-07)
Bacteroides fragilis is an important opportunistic pathogen of humans and is resistant to many drugs commonly used to treat anaerobic infections, including P-lactams. A strain set comprised of B. fragilis isolates producing ...
The nucleotide sequence of the Pseudomonas aeruginosa pyrE-crc-rph region and the purification of the crc gene product.
(East Carolina University, 1996-10)
The gene (crc) responsible for catabolite repression control in Pseudomonas aeruginosa has been cloned and sequenced. Flanking the crc gene are genes encoding orotate phosphoribosyl transferase (pyrE) and RNase PH (rph). ...
Nucleotide sequence of the phosphoprotein (P) gene of Newcastle disease virus (strain Beaudette C).
(East Carolina University, 1992-02)
Analysis of rRNA restriction fragment length polymorphisms from Bacteroides spp. and Bacteroides fragilis isolates associated with diarrhea in humans and animals.
(East Carolina University, 1992-04)
The Escherichia coli rRNA operon rrnB was used as a 32P-labeled hybridization probe in Southern blots of
genomic DNAs from representative strains of the saccharolytic, gram-negative, obligate anaerobes of the genus
Bacteroides. ...
Essential Role of the Iron-Regulated Outer Membrane Receptor FauA in Alcaligin Siderophore-Mediated Iron Uptake in Bordetella Species
(East Carolina University, 1999-10)
Phenotypic analysis using heterologous host systems localized putative Bordetella pertussis ferric alcaligin transport genes and Fur-binding sequences to a 3.8-kb genetic region downstream from the alcR regulator gene. ...
Isolation and characterization of Bordetella bronchiseptica mutants deficient in siderophore activity.
(East Carolina University, 1993-02)
Iron acquisition by the gram-negative pathogens Bordetella bronchiseptica and Bordetella pertussis is thought to occur by hydroxamate siderophore-mediated transport as well as an apparently siderophore-independent process ...
A two-component response regulator, gltR, is required for glucose transport activity in Pseudomonas aeruginosa PAO1.
(East Carolina University, 1996-10)
A 729-bp open reading frame (gltR) was identified in Pseudomonas aeruginosa PAO1 that encodes a product homologous to the two-component response regulator family of proteins. Disruption of gltR caused loss of glucose ...
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 ...
Oxidative stress response in an anaerobe, Bacteroides fragilis: a role for catalase in protection against hydrogen peroxide.
(East Carolina University, 1996-12)
Survival of Bacteroides fragilis in the presence of oxygen was dependent on the ability of bacteria to synthesize
new proteins, as determined by the inhibition of protein synthesis after oxygen exposure. The B. fragilis ...
Regulation of Bacteriodes fragilis katB mRNA by oxidative stress and carbon limitation.
(East Carolina University, 1997-11)
Regulation of the katB catalase gene in the anaerobic bacterium Bacteroides fragilis was studied. Northern
blot hybridization analyses revealed that katB was transcribed as an approximately 1.6-kb monocistronic
mRNA. The ...
