What is campylobacter?

People are most often infected by eating or drinking contaminated food, water or unpasteurized milk. Most people infected with campylobacter are ill for three to five days, but in about 20 percent of the cases, symptoms may persist for two weeks or longer. Sometimes people are ill enough to behospitalized.

How do people get campylobacter?

People can become infected by eating raw or undercooked meat or poultry from infected animals, from drinking unpasteurized (raw) milk and from eating dairy products made from unpasteurized milk. Direct contact with infected pets, especially kittens and puppies, can also be a source of infection. Many animals carry the disease without appearing ill. Campylobacter is commonly found in the stomach and intestines of cattle, sheep, pigs, goats, dogs, cats, rodents, turkeys and chickens.

How is campylobacter infection diagnosed and treated?

Campylobacter is usually diagnosed by a lab test called a stool culture. Your health care provider will give you the special container you need to collect a stool specimen. It usually takes several days before the stool test results are ready. In general, people who are otherwise healthy recover without medical treatment. Sometimes antibiotics are used when a person is severely ill or if they work in jobs where there is risk of passing the disease to others. If a person becomes dehydrated, hospitalization may be necessary for fluid replacement.
