title: Campylobacter fetus subspecies fetus infection.
abstract: During a six-year period five patients with Campylobacter fetus subspecies fetus infections were seen at the Mayo Clinic in Rochester, Minnesota. Bacteremia was observed in two patients, one presenting with aortic valve endocarditis and the other with abdominal atherosclerotic aortic aneurysm. C. fetus subsp. fetus was isolated from tibial tissue of a patient with osteomyelitis. Diarrhea was the main complaint of two further patients, and was also mentioned by the patient with the aortic aneurysm. Despite the use of incubation conditions and selective media geared to detect only Campylobacter jejuni, C. fetus subsp. fetus was isolated from stool specimens of the two patients with gastrointestinal symptoms. The fact that three of five C. fetus subsp. fetus infections observed in this study were associated with intestinal symptoms further supports the importance of the gastrointestinal tract in the pathogenesis of C. fetus subsp. fetus infections.
