Microbial cell surface glycans in the form of glycolipids and glycoproteins frequently play important roles in cell-cell interaction and host immune responses. Given the likely importance of these surface structures in the survival and pathogenesis of Campylobacter jejuni, a concerted effort has been made to characterise these determinants genetically and structurally since the genome was sequenced in 2000. We review the considerable progress made in characterising the Campylobacter glycome including the lipooligosaccharide (LOS), the capsule and O- and N-linked protein glycosylation systems, and speculate on the roles played by glycan surface structures in the life-cycle of C. jejuni.
