A comparative analysis of 60 complete Burkholderia genomes was conducted to obtain insight in the evolutionary history behind the diversity and pathogenicity at species level. A concatenated multiprotein phyletic pattern and a dataset with Burkholderia clusters of orthologous genes (BuCOGs) were constructed. The extent of horizontal gene transfer (HGT) was assessed using a Markov based probabil...

Molecular-based techniques are becoming desirable as tools for identification of infectious diseases. Amongst the Burkholderia spp., there is a need to differentiate Burkholderia pseudomallei from Burkholderia cepacia, as misidentification could lead to false treatment of patients. In this study, conventional PCR assay targeting three genes was developed. Primers were designed for the amplifica...

Strain LB400T 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 ...

Behaviour of dry bean cultivars to bacterial wilt The objective of this research was to evaluate the reaction of 40 dry bean (Phaseolus vulgaris) cultivars inoculated with two isolates of Curtobacterium flaccumfaciens pv. flacummfaciens, and the shoot dry weight of resistant and susceptible dry bean cultivars inoculated or not with this bacteria. The cultivars IAC Carioca Aruã, IAC Carioca Akyt...

Misidentifications of Burkholderia pseudomallei as Burkholderia cepacia by Vitek 2 have occurred. Multidimensional scaling ordination of biochemical profiles of 217 Malaysian and Australian B. pseudomallei isolates found clustering of misidentified B. pseudomallei isolates from Malaysian Borneo. Specificity of B. pseudomallei identification in Vitek 2 and potentially other automated identificat...

The serological diagnosis of melioidosis is carried out using the indirect hemagglutination assay. We looked at the reactivity of sera from culture-proven cases of melioidosis from north Queensland against antigens derived from Burkholderia pseudomallei, B. thailandensis, and B. cepacia. Cross-reactivity between sera from culture-positive cases of melioidosis and B. thailandensis was demonstrated.

The Burkholderia cenocepacia epidemic ET12 lineage belongs to the genomovar IIIA including the reference strain J2315, a highly transmissible epidemic B. cenocepacia lineage. Members of this lineage are able to cause lung infections in immunocompromised and cystic fibrosis patients. In this study, we describe the genome of F01, an environmental B. cenocepacia strain isolated from soil in Burkin...

AIM To re-examine the previously reported in vitro interaction of insulin with Burkholderia pseudomallei, in the light of a suggestion that the interaction may have resulted from the presence of the preservative m-cresol in commercial preparations. METHODS Broth culture studies of B pseudomallei were performed with and without the addition of m-cresol and various preparations of insulin. RE...
