Deciphering Campylobacter jejuni cell surface interactions from the genome sequence.

The completion of the Campylobacter jejuni genome sequence is a landmark in Campylobacter research. Discoveries directly arising from these data include the identification of a capsular polysaccharide, extensive capacity for phase variable gene expression and lipo-oligosaccharide structural phase variation. The recent identification of a unique system of general protein glycosylation in C. jejuni, a C. jejuni protein that is translocated into eukaryotic cells, and plasmid-encoded components of a putative type IV secretion system are likely to be significant in terms of the host-pathogen interaction.
