Heterogeneity of a Campylobacter jejuni Protein That Is Secreted through the Flagellar Filament [link]Paper  doi  abstract   bibtex   
Cj0859c, or FspA, is a small, acidic protein of Campylobacter jejuni that is expressed by a σ28 promoter. Analysis of the fspA gene in 41 isolates of C. jejuni revealed two overall variants of the predicted protein, FspA1 and FspA2. Secretion of FspA occurs in broth-grown bacteria and requires a minimum flagellar structure. The addition of recombinant FspA2, but not FspA1, to INT407 cells in vitro resulted in a rapid induction of apoptosis. These data define a novel C. jejuni virulence factor, and the observed heterogeneity among fspA alleles suggests alternate virulence potential among different strains.
