Inhibition of Quorum Sensing by a Pseudomonas aeruginosa dksA Homologue
(East Carolina University, 2001-03)
The Pseudomonas aeruginosa las (lasR-lasI) and rhl (rhlR-rhlI) quorum-sensing systems regulate the expression of several virulence factors, including elastase and rhamnolipid. P. aeruginosa strain PR1-E4 is a lasR deletion ...
The Global Carbon Metabolism Regulator Crc Is a Component of a Signal Transduction Pathway Required for Biofilm Development by Pseudomonas aeruginosa
(East Carolina University, 2000-01)
The transition from a planktonic (free-swimming) existence to growth attached to a surface in a biofilm occurs in response to environmental factors, including the availability of nutrients. We show that the catabolite ...
Upregulation of Human T-Cell Leukemia Virus Type 1 Antisense Transcription by the Viral Tax Protein
(East Carolina University, 2009-02)
Several studies have recently demonstrated the existence of human T-cell leukemia virus type 1 (HTLV-1) antisense transcripts, which allow the synthesis of the newly described HBZ protein. Although previous reports have ...
What Constitutes an Extended-Spectrum beta-lactamase?
(East Carolina University, 2002-02)
Aerobic-Type Ribonucleotide Reductase in the Anaerobe Bacteroides fragilis
(East Carolina University, 2002-02)
Bacteroides fragilis, a component of the normal intestinal flora, is an obligate anaerobe capable of long-term survival in the presence of air. Survival is attributed to an elaborate oxidative stress response that controls ...
Adaptations of Pseudomonas aeruginosa to the Cystic Fibrosis Lung Environment Can Include Deregulation of zwf, Encoding Glucose-6-Phosphate Dehydrogenase
(East Carolina University, 2005-11)
Cystic fibrosis (CF) patients are highly susceptible to chronic pulmonary disease caused by mucoid Pseudomonas aeruginosa strains that overproduce the exopolysaccharide alginate. We showed here that a mutation in zwf, ...
Raman spectroscopy: the gateway into tomorrow's virology
(East Carolina University, 2006-06-28)
In the molecular world, researchers act as detectives working hard to unravel the mysteries surrounding cells. One of the researchers' greatest tools in this endeavor has been Raman spectroscopy. Raman spectroscopy is a ...
The Pseudomonas Quinolone Signal Regulates rhl Quorum Sensing in Pseudomonas aeruginosa
(East Carolina University, 2000-05)
The opportunistic pathogen Pseudomonas aeruginosa uses intercellular signals to control the density-dependent expression of many virulence factors. The las and rhl quorum-sensing systems function, respectively, through the ...
Identification, cloning and functional characterization of novel beta-defensins in the rat (Rattus norvegicus)
(East Carolina University, 2006-02-04)
Background
beta-defensins are small cationic peptides that exhibit broad spectrum antimicrobial properties. The majority of beta-defensins identified in humans are predominantly expressed in the male reproductive tract ...
Response to Kuhse
(East Carolina University, 2002-08)
In this short paper, we respond to critics of our original paper, The agony of agonal respiration: is the
last gasp necessary?. A common thread in both Hawryluckâ s and Kuhseâ s responses is the difficulties
encountered ...
