Campylobacter jejuni

Host

Animals and humans

Transmission

Fecal-oral, ingestion of contaminated food or water, and the eating of raw meat

Case Fatality Ratio

Does not commonly cause death, it has been estimated that approximately 124 persons with Campylobacter infections die each year.

Case Fatality Ratio
Case Fatality Ratio Pathway/conditions Population References
2.9 (95% CI: 1.9-40) Infected domestically

Within first month following illness

US (Ternhag et al, 2005)
0.3 (95% CI: 0.04-0.8) Infected Abroad

Within first month following illness

(Ternhag et al, 2005)

Morbidity Rate

It is estimated to affect over 2.4 million persons every year, or 0.8% of the population (CDC).

Incubation Period

3-5 days or up to a week (Medscape)

Burden of Disease


Microbiology

Gram-negative, spiral, and microaerophilic. Motile, with either unipolar or bipolar flagella, the organisms have a characteristic spiral/corkscrew appearance and are oxidase-positive

Environmental Survival


Recommended Dose Response Model

Dose response models for Campylobacter
Beta-Poisson, α is 0.14, N50 is 890.38
