    Description: A study was conducted to determine the role of the pili expressed by Haemophilus ducreyi in the pathogenesis of the genital ulcer disease chancroid. A gene encoding the 24K protein of fine, tangled pili, termed ftpA, was isolated and examined by molecular techniques. The results showed that the FtpA protein lacked homology with other pilins, but shared homoloy with proteins that polymerize ordered rings in Escherichia coli and Treponema pallidum.

    Description: The nucleotide sequence of the gene encoding the major outer membrane protein (MOMP) of Haemophilus ducreyi was analyzed by sodium dodecyl sulfate-polyacrilamide gel electrophoresis. Nucleotide sequence analysis of the MOMP gene of Haemophilus ducreyi indicated the presence of two OmpA homologs that were encoded by momp and ompA2 genes. Southern blot analysis also indicated the high degree of similarity between MOMP and OmpA2 which existed in tandem in the different strains of Haemophilus ducreyi.

    Description: Haemophilus ducreyi expresses 2 OmpA homologs, designated MOMP and OmpA2, whose genes are arranged in tandem on the chromosome. Northern blot analysis indicated that momp and ompA2 are transcribed independently. Sequences of the momp open reading frame (ORF) lacking the transcriptional start site were amplified by PCR, and an Omega-Km2 cassette was ligated into the ORF. A plasmid containing this construction was electroporated into H. ducreyi 35000HP, and an isogenic MOMP-deficient mutant (35000HP-SMS2) was generated by allele exchange. In Southern blotting, 35000HP-SMS2 contained one copy of the Omega-Km2 cassette in momp. 35000HP and 35000HP-SMS2 had similar outer membrane protein (OMP) and lipooligosaccharide profiles and growth rates except for up-regulation of a putative porin protein in the mutant. Five subjects were inoculated with three doses of live 35000HP-SMS2 on one arm and two doses of live 35000HP and one dose of a heat-killed control on the other arm in a double-blind escalating dose-response trial. Pustules developed at 7 of 10 sites inoculated with 35000HP and at 6 of 15 sites inoculated with 35000HP-SMS2 (P = 0.14). 35000HP and 35000HP-SMS2 were recovered at similar rates from daily surface cultures and semiquantitative cultures. The data suggest that expression of MOMP is not required for pustule formation by H. ducreyi in the human model of infection.
