Campylobacter infection occurs in the small intestine from bacteria called Campylobacter jejuni. It is a type of food poisoning.
Campylobacter enteritis is a common cause of intestinal infection. These bacteria are also one of the many causes of traveler's diarrhea or food poisoning.
People most often get infected by eating or drinking food or water that contains the bacteria. The most commonly contaminated foods are raw poultry, fresh produce, and unpasteurized milk.
A person can also be infected by close contact with infected people or animals.
Symptoms start 2 to 4 days after being exposed to the bacteria. They often last a week, and may include:
Exams and Tests
Your health care provider will perform a physical exam. These tests may be done:
- Complete blood count (CBC) with differential
- Stool sample testing for white blood cells
- Stool culture for Campylobacter jejuni
The infection almost always goes away on its own, and often does not need to be treated with antibiotics. Severe symptoms may improve with antibiotics.
The goal is to make you feel better and avoid dehydration. Dehydration is a loss of water and other fluids in the body.
These things may help you feel better if you have diarrhea:
- Drink 8 to 10 glasses of clear fluids every day. For people who do not have diabetes, fluids should contain salts and simple sugars. For those with diabetes, sugar-free fluids should be used.
- Drink at least 1 cup (240 milliliters) of liquid every time you have a loose bowel movement.
- Eat small meals throughout the day instead of 3 big meals.
- Eat some salty foods, such as pretzels, soup, and sports drinks.
- Eat some high-potassium foods, such as bananas, potatoes without the skin, and watered-down fruit juices.
Most people recover in 5 to 8 days.
When a person's immune system does not work well, the Campylobacter infection may spread to the heart or brain.
Other problems that may occur are:
