Benanti et al. report that Burkholderia pseudomallei and Burkholderia mallei bacteria express proteins that mimic Ena/Vasp family proteins to polymerize actin, thereby inducing actin-based motility. Thus, bacteria can use the various cellular actin polymerization mechanisms for intra- and inter-cellular dissemination.

The MIC(50) and MIC(90) values of doripenem, determined by Etest, for 110 isolates of Burkholderia pseudomallei were 0.5 and 0.75 microg/ml, respectively. There were significant correlations between MICs determined by Etest and MICs determined by agar dilution, MICs determined by Etest and inhibition zone size, and MICs determined by agar dilution and inhibition zone size.

Burkholderia multivorans NKI379 is a soil bacterium that exhibits an antagonistic effect against the growth of Burkholderia pseudomallei, the causative agent of the infectious disease melioidosis. We report the draft genomic sequence of B. multivorans NKI379, which has a G+C content of 67% and 5,203 candidate protein-encoding genes.

Here, we present the draft genome sequences of 80 isolates of Burkholderia pseudomallei. The isolates represent clinical cases of melioidosis and environmental isolates from regions in Australia and Papua New Guinea where B. pseudomallei is endemic. The genomes provide further context for the diversity of the pathogen.

Within 2 months of acquiring glanders, a patient developed 8-, 16-, and 4-fold increases, respectively, in specific IgA, IgG, and IgM serological titers against Burkholderia mallei. Within 14 months of infection, the titers decreased to the baseline. Serum from this patient was also highly reactive against Burkholderia pseudomallei whole cells. Burkholderia mallei whole cells did not react with...

Rhizobia form specialized nodules on the roots of legumes (family Fabaceae) and fix nitrogen in exchange for carbon from the host plant. Although the majority of legumes form symbioses with members of genus Rhizobium and its relatives in class Alphaproteobacteria, some legumes, such as those in the large genus Mimosa, are nodulated predominantly by betaproteobacteria in the genera Burkholderia ...

Strain LB400 is the best-studied polychlorinated biphenyl (PCB) degrader. This organism has previously been allocated in the genus Burkholderia, since its 16S rRNA gene sequence shows 98?6% sequence similarity to the type strains of Burkholderia graminis and Burkholderia terricola. A polyphasic study was undertaken to clarify the actual taxonomic position of this biotechnologically important or...

The formation of cluster roots by plants represents a highly efficient strategy for acquisition of sparingly available phosphate. This particular root type is characterized by a densely branched structure and high exudation of organic acids and protons, which are likely to influence the resident bacterial community. Until now, the identity of the bacterial populations living in cluster roots ha...
