The bacterium Campylobacter jejuni (C. jejuni) and less commonly Campylobacter coli (C. coli) are the usual causes of campylobacteriosis.
Campylobacter species are motile, comma-shaped, microaerophilic Gram-negative bacilli that cause gastroenteritis.
Symptoms usually occur 2-5 days after exposure and may persist for one to two weeks. Illness is characterized by diarrhea, abdominal pain, malaise, fever, nausea and vomiting. The symptoms can vary from mild to severe, can mimic appendicitis and can also be asymptomatic. Relapses can occur. Blood and mucus may be present in liquid stools. The illness can also mimic acute appendicitis. Less common presentations include typhoid-like syndrome, febrile convulsions, or meningitis (the bacteria infects the membrane which lines the surface of the brain); post-infectious complications include reactive arthritis, febrile convulsions or Guillain-Barre syndrome.
Modes of Transmission:
Ingestion of the organisms in undercooked meat and poultry, contaminated food and water, or raw milk and other dairy products; contact with infected pets (especially puppies and kittens), farm animals or infected infants. The infective dose is often low. Person to person transmission appears uncommon
Usually 2-5 days, with a range of 1-10 days, depending on dose ingested.
Period of Communicability:
Several days to several weeks, individuals without antibiotic treatment may shed Campylobacter bacteria in the feces for 2-7 weeks.
Lasting immunity to serologically related strains follows infection. In developing countries, most people develop immunity in the first 2 years of life. Behavioural risk factors include:
- Anal-oral contact (sexual)
- Animal contact
- Poor hand hygiene practices
- Consumption of raw/undercooked meat/poultry
- Consumption of unpasteurized milk/milk products
- Travel outside province/country within last 10 days
Diagnosis & Laboratory Testing
Confirmation of infection by positive culture of Campylobacter species or detection of Campylobacter species by nucleic acid amplification testing (NAAT) from an appropriate clinical specimen (e.g., stool, urine, body fluids)
Treatment & Case Management
Treatment recommendations are under the direction of the attending health care provider.
Inform patients that symptomatic cases will be excluded from conducting activities in high-risk settings such as the food industry, healthcare, or daycare until symptom-free for 24 hours, or 48 hours after completion of antibiotic or anti-diarrheal medications.
