Abstract
Using antisera raised against serotype 2 and 3 fimbrial subunits from Bordetella pertussis, serologically related polypeptides were detected in Bordetella bronchiseptica, Bordetella parapertussis and Bordetella avium strains. The two B. pertussis fimbrial subunits, and three of the serologically related B. bronchiseptica polypeptides, were shown to be very similar in amino acid composition and N-terminal amino acid sequence. Homology was observed between the N-termini of these polypeptides, and fimbrial subunits from Escherichia coli, Haemophilus influenzae and Proteus mirabilis. A synthetic oligonucleotide probe, derived from the N-terminal sequence of the B. pertussis serotype 2 fimbrial subunit, was used to identify fimbrial genes in genomic Southern blots. The results suggested the presence of multiple fimbrial subunit genes in B. pertussis, B. bronchiseptica and B. parapertussis. The DNA probe was used to clone one of the three tentative fimbrial subunit genes detected in B. pertussis.
