Members of the Burkholderia species can cause a range of severe, often fatal, respiratory diseases. A variety of in vitro models of infection have been developed in an attempt to elucidate the mechanism by which Burkholderia spp. gain entry to and interact with the body. The majority of studies have tended to focus on the interaction of bacteria with phagocytic cells with a paucity of informati...
Numerous gram-negative bacterial pathogens regulate virulence factor expression by using a cell density mechanism termed quorum sensing (QS). An in silico analysis of the Burkholderia mallei ATCC 23344 genome revealed that it encodes at least two luxI and four luxR homologues. Using mass spectrometry, we showed that wild-type B. mallei produces the signaling molecules N-octanoyl-homoserine lact...
Burkholderia mallei is a gram-negative bacterial pathogen of domestic equidae and humans that can cause severe, rapidly life-threatening pneumonic infections. Little is known regarding the role of chemokines and early cellular immune responses in protective immunity to pulmonary infection with B. mallei. Although the role of MCP-1 in gram-positive bacterial infections has been previously invest...
Actin-based motility of the melioidosis pathogen Burkholderia pseudomallei requires BimA. We report a high degree of conservation of bimA in 99 B. pseudomallei isolates from the area of endemicity. A geographically restricted subset of B. pseudomallei isolates harbored a B. mallei-like bimA allele (12.1%), confounding a differential diagnostic test based on amplification of species-specific bim...
Our laboratory has developed more than a hundred mouse monoclonal antibodies (MAbs) against Burkholderia pseudomallei and Burkholderia mallei. These antibodies have been categorized into different groups based on their specificities and the biochemical natures of their target antigens. The current study first examined the bactericidal activities of a number of these MAbs by an in vitro opsonic ...
Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is increasingly used for rapid bacterial identification. Studies of Burkholderia pseudomallei identification have involved small isolate numbers drawn from a restricted geographic region. There is a need to expand the reference database and evaluate B. pseudomallei from a wider geographic distribution th...
We confirm a natural infection of dromedaries with glanders. Multilocus variable number tandem repeat analysis of a Burkholderia mallei strain isolated from a diseased dromedary in Bahrain revealed close genetic proximity to strain Dubai 7, which caused an outbreak of glanders in horses in the United Arab Emirates in 2004.
