Campylobacter jejuni
Host
Animals and humans
Transmission/Exposure Routes
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 | 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) |
Incubation Period
3-5 days or up to a week (Medscape)
Burden of Disease
It is estimated to affect over 2.4 million persons every year, or 0.8% of the population (CDC).
Duration of infectiousness and disease
Symptomology
Illness can cause symptoms beginning 2-5 days after exposures. These symptoms include abdominal pain, cramping, diarrhea, and fever.
Excretion Rates (see Exposure)
Immunity
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
