Campylobacter gastroenteritis, bacterial gastroenteritis in humans or other mammals, caused by infection with Campylobacter jejuni, most commonly acquired from contact with infected individuals; from consumption of contaminated food, water, or other beverages; or from exposure to contaminated objects or environmental surfaces. Infection is usually characterized by diarrhea that may be bloody, abdominal pain with cramps and fever. The cause is usually ingestion of contaminated food or water. Generally, adherence to good personal hygiene by personnel before and after all contacts with patients and their food and standard precautions will minimize the risk of transmission of enteric pathogens.
