Abstract:
Burkholderia pseudomalleiis a Gram-negative bacterium that causes melioidosis, which can be fatal in humans. Melioidosis is prevalent in the tropical regions of Southeast Asia and Northern Australia. Ecological data have shown that this bacterium can survive as a free-living organism in environmental niches, such as soil and water, as well as a parasite living in host organisms, such as ameba, plants, fungi, and animals. This review provides an overview of the survival and adaptation ofB. pseudomalleito stressful conditions induced by hostile environmental factors, such as salinity, oxidation,

Abstract:
ABSTRACTBurkholderia pseudomallei, the etiological agent for melioidosis, is an important cause of community-acquired sepsis in northern Australia and northeast Thailand. Due to the rapid dissemination of disease in acute melioidosis, we hypothesized that dendritic cells (DC) could act as a vehicle for dissemination ofB. pseudomallei. Therefore, this study investigated the effect ofB. pseudomalleiinfection on DC migration capacity and whether migration of DC enabled transportation ofB. pseudomalleifrom the site of infection.B. pseudomalleistimulated significantly increased migration of bone ma

Previous reports in the literature suggest that Burkholderia pseudomallei strains can be differentiated on the basis of animal virulence. Twenty environmentally and clinically derived isolates of Burkholderia pseudomallei were examined for the production of exoenzymes, morphological and biochemical phenotypes and virulence for Syrian golden hamsters. The partial sequence of the 16S ribosomal RNA [rRNA] genes from a number of these strains was also determined. Based upon these observations, it is suggested that highly virulent Burkholderia pseudomallei strains are true Burkholderia pseudomallei

Abstract:
Burkholderia pseudomallei has been shown to produce more than one capsular polysaccharide (CPS). Analysis of the B. pseudomallei genome has revealed that the organism contains four CPS operons (I–IV). One of these operons (CPS III) was selected for further study. Comparative sequencing analysis revealed that the genes encoding CPS III are present in B. pseudomallei and Burkholderia thailandensis but not in Burkholderia mallei. In this study, CPS III was not found to contribute to the virulence of B. pseudomallei. Strains containing mutations in CPS III had the same LD50 value as the wild-type

Monoclonal antibodies (MAb) were produced against two B. pseudomallei high-purified membrane proteins with Mr 29 kDa (p29) and 45 kDa (p45). Monoclonal antibodies from culture supernatant fluids of 4F2 and 1G11 clones showed specific interaction with protein moiety of p29 both Burkholderia pseudomallei and Burkholderia mallei in ELISA and Western blotting. However, MAb of 3G4 clone were bound to the LPS-protein structures of these microbial cells.

Burkholderia pseudomallei causes melioidosis. Sequence typing this pathogen can reveal geographical origin and uncover epidemiological associations. Here, we describe B. pseudomallei genes encoding putative penicillin binding proteins (PBPs) and investigate their utility for determining phylogeography and differentiating closely related species. We performed in silico analysis to characterize 10 PBP homologs in B. pseudomallei 1026b. As PBP active site mutations can confer β-lactam resistance in Gram-negative bacteria, PBP sequences in two resistant B. pseudomallei strains were examined for si

Abstract:
ABSTRACT Because of Burkholderia pseudomallei's classification as a select agent in the United States, genetic manipulation of this bacterium is strictly regulated. Only a few antibiotic selection markers, including gentamicin, kanamycin, and zeocin, are currently approved for use with this bacterium, but wild-type strains are highly resistant to these antibiotics. To facilitate routine genetic manipulations of wild-type strains, several new tools were developed. A temperature-sensitive pRO1600 broad-host-range replicon was isolated and used to construct curable plasmids where the Flp and Cre

Abstract:
ABSTRACTBurkholderia pseudomallei, the etiologic agent of melioidosis, is a CDC tier 1 select agent that causes severe disease in both humans and animals. Diagnosis and treatment of melioidosis can be challenging, and in the absence of optimal chemotherapeutic intervention, acute disease is frequently fatal. Melioidosis is an emerging infectious disease for which there are currently no licensed vaccines. Due to the potential malicious use ofB. pseudomalleias well as its impact on public health in regions where the disease is endemic, there is significant interest in developing vaccines for imm

Burkholderia pseudomallei is the etiological agent of melioidosis. It is a gram-negative bacillus present in environment and intrinsically resistant to many antibiotics including aminoglycosides. However, recently aminoglycoside susceptible B. pseudomallei has been isolated from melioidosis cases and reported from some countries of the world. But, such aminoglycoside susceptible B. pseudomallei has never been detected in Bangladesh either from melioidosis cases or from environment. All the B. pseudomallei isolated so far in Bangladesh were resistant to gentamicin and other aminoglycosides. Her

Burkholderia pseudomallei is the causative agent of human and animal melioidosis. The role of quorum sensing (QS) in the in vivo pathogenicity of B. pseudomallei via inhalational exposure of BALB/c mice and intraperitoneal challenge of Syrian hamsters has not been reported. This investigation demonstrates that B. pseudomallei encodes a minimum of three luxI and five luxR homologues that are involved in animal pathogenicity. Mass spectrometry analysis of culture supernatants revealed that wild-type B. pseudomallei and the luxI mutants synthesized numerous signalling molecules, including N-octan

B. pseudomallei cells were tethered to the external amoebic surface via their flagella. MM35, the flagellum-lacking fliC knockout derivative of B. pseudomallei NCTC 1026b did not demonstrate flagellum-mediated endocytosis in timed coculture, confirming that an intact flagellar apparatus assists B. pseudomallei entry into A. astronyxis.
