Campylobacter jejuni is a major cause of sporadic bacterial diarrhea in the United States. Markedly elevated levels of antibodies to C. jejuni typically indicate recent or ongoing infection, even though stool cultures may be negative. Approximately 30% of Guillain–Barré syndrome cases are associated with recent C. jejuni infection due to molecular mimicry between C. jejuni antigens and neuronal gangliosides.
