Campylobacter jejuni infections are one of the leading causes of human gastroenteritis and
are suspected of being a precursor to Guillain–Barré and Miller–Fisher syndromes.
Recently, the complete genome sequence of C. jejuni NCTC 11168 was described. In this
study, the molecular structure of the lipooligosaccharide and capsular polysaccharide of C.
jejuni NCTC 11168 was investigated. The lipooligosaccharide was shown to exhibit
carbohydrate structures analogous to the GM1a and GM2 carbohydrate epitopes of human …

Campylobacter jejuni infections are one of the leading causes of human gastroenteritis and are suspected of being a precursor to Guillain–Barré and Miller–Fisher syndromes. Recently, the complete genome sequence of C. jejuni NCTC 11168 was described. In this study, the molecular structure of the lipooligosaccharide and capsular polysaccharide of C. jejuni NCTC 11168 was investigated. The lipooligosaccharide was shown to exhibit carbohydrate structures analogous to the GM1a and GM2 carbohydrate epitopes of human gangliosides (shown below):
The high Mr capsule polysaccharide was composed of β‐d‐Ribp, β‐d‐GalfNAc, α‐d‐GlcpA6(NGro), a uronic acid amidated with 2‐amino‐2‐deoxyglycerol at C‐6, and 6‐O‐methyl‐d‐glycero‐α‐l‐gluco‐heptopyranose as a side‐branch (shown below):
The structural information presented here will aid in the identification and characterization of specific enzymes that are involved in the biosynthesis of these structures and may lead to the discovery of potential therapeutic targets. In addition, the correlation of carbohydrate structure with gene complement will aid in the elucidation of the role of these surface carbohydrates in C. jejuni pathogenesis.
