Organism Additional Information Campylobacter jejuni is a microaerophilic, Gram-negative, human pathogen that is the major cause of bacterial food-borne diarrhoea (gastroenteritis). It is most frequently responsible for a form of post-infection neuromuscular paralysis known as Guillain Barre' syndrome. It also leads to an immunoproliferative small intestine disease that is a rare malignant lymphoma of the intestine. Motility is essential for pathogenicity.

Protein Glycosylation- Implication Through modelling, it was shown that glycosylation significantly affects the conformation of MOMP and modulates BgAg-binding capacity. The glycosylation also facilitates biofilm formation cell-cell binding and adhesion to Caco-2 cells. Role of O-glycosylation in pathogenesis was demonstrated by glycosylation-driven optimal colonization of chickens by C. jejuni.
