Previous studies have shown that appendage pili of Burkholderia cepacia strains isolated from patients with cystic fibrosis (CF) at The Hospital for Sick Children, Toronto, Canada, mediate adherence to mucus glycoproteins and also enhance adherence to epithelial cells. The specific pilin-associated adhesin molecule is a 22-kDa protein. In the present study we purified the major subunit pilin (17 kDa) and immunolocalized it to peritrichously arranged pili. On the basis of their novel morphological appearance as giant intertwined fibers, we refer to them as cable (Cbl) pili. Using an oligonucleotide probe corresponding to regions of the N-terminal amino acid sequence of the pilin subunit, we detected the encoding cblA gene in a chromosomal DNA library. Sequencing revealed this structural gene to be 555 bp in length, encoding a leader sequence of 19 amino acids, a cleavage site between the alanine at position 19 and the valine at position 20, and a mature pilin sequence of 165 amino acids. The calculated molecular mass is 17.3 kDa. Hydrophobic plus apolar amino acids account for 60% of the total residues. The pilin exhibits some similarities in its amino acid sequence to colonization factor antigen I and CS1 fimbriae of Escherichia coli. With the cblA gene used as a probe, hybridization assays of 59 independent isolates, including those from several geographically separated CF centers, plus environmental and clinical (non-CF) strains, gave positive results with all of the 15 CF-associated B. cepacia isolates from Toronto, plus a single strain from one other CF center (Jackson, Mississippi). The cblA gene is the first pilin subunit gene of B. cepacia to be identified.
