Campylobacter infection is one of the leading causes of acute diarrhea worldwide and is the most commonly reported bacterial cause of acute gastroenteritis in developed countries. It is also a major cause of travelers' diarrhea.
Campylobacter jejuni is the primary cause of acute enteritis, causing 80% to 90% of all cases of recognized illness due to Campylobacter infection. Campylobacter coli is the second most common cause of acute enteritis. Campylobacter fetus is a rare cause of extra-intestinal infection, mainly in immunocompromised people.
Campylobacters are carried by a wide variety of wild and domestic animals, most commonly birds. Most C jejuni infections come from infected poultry.
Diarrhea is usually self-limited and resolves in 5-7 days. Campylobacter bacteremia is very rare.
Fluid and electrolyte replacement is essential. Only a small proportion of patients benefit from antimicrobial therapy.
C jejuni infection is a commonly identified antecedent to Guillain-Barre syndrome. C fetus is associated with endovascular problems (e.g., mycotic aneurysm, septic thrombophlebitis).
Bacteria of the genus Campylobacter cause a variety of infections, most commonly acute diarrheal illnesses. In patients with liver disease, immunocompromised people, and the elderly, Campylobacter infection can cause bacteremia or extraintestinal infection. There are many species of Campylobacter. Eleven of them cause human illness, including enteric and extraintestinal disease. The major human pathogens are C jejuni and C coli, which usually cause acute enteritis, and C fetus, which is the major pathogen causing extraintestinal illnesses.
