Bacteria of the Burkholderia cepacia complex (Bcc) persist in the airways of people with cystic fibrosis (CF) despite the continuous recruitment of neutrophils. Most members of Bcc are multidrug resistant and can form biofilms. As such, we sought to investigate whether biofilm formation plays a role in protecting Bcc bacteria from neutrophils. Using the neutrophil-like, differentiated cell line...
The bacterium Burkholderia ubonensis is commonly co-isolated from environmental specimens harbouring the melioidosis pathogen, Burkholderia pseudomallei. B. ubonensis has been reported in northern Australia and Thailand but not North America, suggesting similar geographic distribution to B. pseudomallei. Unlike most other Burkholderia cepacia complex (Bcc) species, B. ubonensis is considered no...
Definitive identification of the species in the Burkholderia cepacia complex by routine clinical microbiology methods is difficult. Phenotypic tests to identify B. multivorans and B. vietnamiensis have been established; more recent work indicates B. stabilis may also be identified by growth characteristics and biochemical tests. However, attempts to identify genomovars I and III have, thus far,...
Burkholderia cepacia spondylodiscitis is a rare entity that has been reported in only four cases. We hereby report the case of a 43-year-old, previously healthy, woman who was found to have a B. cepacia spondylodiscitis after a cholecystectomy. She was treated with a three-month regimen of ceftazidime and ciprofloxacin with complete clinical, biological, and radiological remission.
The patients with hematologic malignancies are predisposed to develop infections with unusual bacteria, like Burkholderia cepacia, which is frequently resistant to many antibiotics and antiseptics. We present the case of a female patient with acute myeloid leukemia type 2 on the background of myelodysplastic syndrome, from whom Burkholderia cepacia was isolated in blood culture, after the 2(nd)...
Burkholderia cepacia produces at least one extracellular zinc metalloprotease that may be involved in virulence. A B. cepacia zinc metalloprotease gene was cloned using a Burkholderia pseudomallei zinc metalloprotease gene as a probe. The predicted amino acid sequences of these B. cepacia and a B. pseudomallei extracellular zinc metalloproteases indicate that they are similar to the thermolysin...
Burkholderia cepacia has recently been recognized as an important pathogen in chronic lung disease in patients with cystic fibrosis (CF). Because of the social, psychological, and medical implications of the isolation of B. cepacia from CF patients, accurate identification of this organism is essential. We compared the accuracies of four commercial systems developed for the identification of no...
Infection with Burkholderia cepacia due to social contact is well described in patients with cystic fibrosis. However, social transmission to non-cystic fibrosis individuals or chronic colonisation in non-cystic fibrosis individuals has not been described. A report of B cepacia bronchiectasis is presented where a previously healthy mother of two cystic fibrosis children colonised with B cepacia...
Burkholderia cepacia complex (Bcc) bacteria possess biotechnologically useful properties that contrast with their opportunistic pathogenicity. The rhizosphere fitness of Bcc bacteria is central to their biocontrol and bioremediation activities. However, it is not known whether this differs between species or between environmental and clinical strains. We investigated the ability of 26 Bcc strai...
Bcep22-like phages are a recently described group of podoviruses that infect strains of Burkholderia cenocepacia. We have isolated and characterized a novel member of this group named DC1. This podovirus shows many genomic similarities to BcepIL02 and Bcep22, but it infects strains belonging to multiple Burkholderia cepacia complex (BCC) species.
