Campylobacter jejuni is a major cause of sporadic bacterial diarrhea in the United States, with poultry the most important source of infection. Markedly elevated levels of antibodies recognizing C. jejuni typically indicate recent or ongoing infection, even though stool cultures may be negative. Neurological complications may follow C. jejuni infection; approximately 30% of Guillain-Barre cases are associated with recent C. jejuni infection. The basis of this association is apparently molecular mimicry between C. jejuni antigens and gangliosides of neuronal cells.
