title: Sequence divergence in type III secretion gene clusters of the Burkholderia cepacia complex.
abstract: The Burkholderia cepacia complex (BCC) comprises a group of bacteria associated with opportunistic infections, especially in cystic fibrosis patients. B. cenocepacia J2315, of the transmissible ET12 lineage, contains a type III secretion (TTS) gene cluster implicated in pathogenicity. PCR and hybridisation assays indicate that the TTS gene cluster is present in all members of the BCC except B. cepacia (formerly genomovar I). The TTS gene clusters of B. cenocepacia J2315 and B. multivorans are similar in organisation but have variable levels of gene identity. Nucleotide sequence data obtained for the equivalent region of the B. cepacia genome indicate the absence of TTS structural genes due to a rearrangement likely to involve more than one step.
