Quorum Sensing Systems Influence Burkholderia Cenocepacia Virulence

Future Microbiology, 2012
Burkholderia cepacia complex strains communicate using N-acyl homoserine lactones and BDSF-dependent quorum sensing (QS) systems. Burkholderia cenocepacia QS systems include CepIR, CciIR, CepR2 and BDSF. Analysis of CepR, CciIR, CepR2 and RpfF (BDSF synthase) QS regulons revealed that these QS systems both independently regulate and coregulate many ...

Isolation ofBurkholderia cenocepaciaandBurkholderia vietnamiensisfrom human sewage

International Journal of Environmental Health Research, 2009
Fresh human sewage was examined from a sewage treatment plant for the presence of members of the Burkholderia cepacia complex (BCC) of bacterial organisms and confirmed the presence of viable B. cenocepacia and B. vietnamiensis, by a combination of cultural, phenotypic and genotypic techniques.

Diving deep for the needle in the haystack: An outbreak investigation of Burkholderia cenocepacia bacteremia

Infection control and hospital epidemiology
In an Indian oncology setting, between August and December 2021, 56 patients, developed Burkholderia cenocepacia bacteremia. An investigation revealed a contaminated batch of the antiemetic drug palonosetron.

Burkholderia cenocepacia Lipopolysaccharide, Lipid A, and Proinflammatory Activity

American Journal of Respiratory and Critical Care Medicine, 2004
Organisms from the Burkholderia cepacia complex are important pathogens in cystic fibrosis and are associated with increased rates of sepsis and death. These organisms comprise nine closely related species known as genomovars. B. cenocepacia (genomovar III) is the most prevalent and appears the most virulent.

Identification of Sodium Chloride-Regulated Genes in Burkholderia cenocepacia

Current Microbiology, 2008
Previous studies have suggested that the airways of cystic fibrosis (CF) patients have elevated sodium chloride (NaCl) levels due to the malfunctioning of the CF transmembrane conductance regulator protein. For bacteria to survive in this high-salt environment, they must adjust by altering the regulation of gene expression. Among the different bacteria

Bovine lactoferrin interacts with cable pili of Burkholderia cenocepacia

BioMetals, 2010
In this study we evaluated the ability of lactoferrin, the most abundant antimicrobial protein in airway secretions, to bind the surface structures of a Burkholderia strain cystic fibrosis-isolated. Burkholderia cenocepacia is a gram-negative bacterium involved as respiratory pathogen in cystic fibrosis patient infections.

Expression and Characterization of Penicillin-Binding Proteins in Burkholderia cenocepacia

Current Microbiology, 2009
Putative penicillin-binding proteins (PBPs) were identified in the genome of the Burkholderia cenocepacia strain J2315 based on homology to E. coli PBPs. The three sequences identified as homologs of E. coli PBP1a, BCAL2021, BCAL0274, and BCAM2632, were cloned and expressed as His(6)-tagged fusion proteins in E. coli.

Differential persistence of Burkholderia multivorans and Burkholderia cenocepacia in the mouse

2004
Members of the Burkholderia cepacia complex (BCC) of organisms are important opportunistic pathogens, particularly in cystic fibrosis (CF) patients. Infection with members of the BCC is associated with poor prognosis. There is speculation that the BCC are intracellular pathogens, surviving and growing inside epithelial cells or professional ...
