Campylobacter jejuni is a bacteria which can cause infectious diarrhea.
Symptoms may include fever, abdominal pain, vomiting and diarrhea – sometimes bloody.
Occasionally the abdominal pain may mimic appendicitis with right lower quadrant pain. CT may reveal mesenteric addentitis but no appendix inflammation.
Exposure to wild birds or ducks e.g. hunters; travel to developing countries or exposure to contaminated water are important historical findings.
Stool cultures, fecal leukocytes and shiga toxin levels can be obtained.
Treatment includes azithromycin 500 mg for 3 – 5 days and maintaining hydration level. (Fluoroquinolone and Bactrim resistance has been growing.)
