PG - 1559-62 AB - We have cloned and sequenced the Brazilian purpuric fever (BPF)-associated Haemophilus influenzae biogroup aegyptius (Hae) pilin gene. The sequence contained a 648-bp open reading frame encoding a mature pilin protein of 191 amino acids with a calculated mass of 20.5 kDa. There was 82% homology between the open reading frames of the BPF strain F3031 and H. influenzae type b (Hib) (strain M43) pilin genes and 71% homology at the amino acid level between the mature pilin proteins. However, areas of diversity were noted throughout the gene. A 17-bp probe corresponding to an area of diversity in the N-terminal region of the BPF-associated gene hybridized with other BPF strains but not with non-BPF Hae or Hib. In summary, the pilin protein of BPF-associated Hae is highly homologous to Hib pilin yet remains structurally distinct.
