Incidence of the cblA major subunit pilin gene amongst Burkholderia species.

PCR-amplification has been used to screen 75 isolates of the Burkholderia cepacia complex for the cblA pilin gene. PCR-amplified products of the correct size (664 bp) were cloned and sequenced and the sequences compared. Apart from in the control, epidemic cystic fibrosis (CF)-associated B. cepacia lineage we also identified, for the first time, cblA genes in a unique, non-CF clinical isolate f...

Transcriptional and posttranscriptional control of cable pilus gene expression in Burkholderia cenocepacia.

Burkholderia cenocepacia is an important member of the Burkholderia cepacia complex, a group of closely related bacteria that inhabits a wide variety of environmental niches in nature and that also colonizes the lungs of compromised humans. Certain strains of B. cenocepacia express peritrichous adherence organelles known as cable pili, thought to be important in the colonization of the lower re...

Mutations in the Gene Encoding the Ancillary Pilin Subunit of the Streptococcus suis srtF Cluster Result in Pili Formed by the Major Subunit Only

Pili have been shown to contribute to the virulence of different Gram-positive pathogenic species. Among other critical steps of bacterial pathogenesis, these structures participate in adherence to host cells, colonization and systemic virulence. Recently, the presence of at least four discrete gene clusters encoding putative pili has been revealed in the major swine pathogen and emerging zoono...

Genetic characterization of a multicomponent signal transduction system controlling the expression of cable pili in Burkholderia cenocepacia.

Cable pili are peritrichous organelles expressed by certain strains of Burkholderia cenocepacia, believed to facilitate colonization of the lower respiratory tract in cystic fibrosis patients. The B. cenocepacia cblBACDS operon encodes the structural and accessory proteins required for the assembly of cable pili, as well as a gene designated cblS, predicted to encode a hybrid sensor kinase prot...

Burkholderia species are major inhabitants of white lupin cluster roots.

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...
