Campylobacteriosis is an infection by one of several species of Campylobacter bacteria, particularly Campylobacter jejuni (C. jejuni). This infection typically causes diarrhea. The infection also can cause fever and abdominal cramps. Humans usually become infected with Campylobacter after eating poorly prepared meat, especially undercooked chicken. Campylobacter is currently the most common bacterial cause of food-borne illness in the United States, producing more infections than either Salmonella or Escherichia coli (E. coli). Infants have an especially high rate of campylobacteriosis because of their immature immune defenses. Young adults also are at higher risk of infection, possibly because they have less experience cooking and handling raw meats. So, they may be exposed more often to potentially contaminated foods.
