Answer

Infections with Campylobacter-like organisms can produce an enterocolitis/proctocolitis syndrome in homosexual males, who are at increased risk for Helicobacter cinaedi and Helicobacter fennelliae infections. [1] Bacteremia can also occur with H fennelliae. [2] C jejuni infections may also produce serious bacteremic conditions in individuals with AIDS. Most reported bacteremias have been due to Campylobacter fetus fetus infection. Campylobacter lari, which is found in healthy seagulls, has also been reported to produce mild recurrent diarrhea in children. Campylobacter upsaliensis may cause diarrhea or bacteremia, while Campylobacter hyointestinalis, which has biochemical characteristics similar to those of C fetus, causes occasional bacteremia in immunocompromised individuals.

Campylobacter organisms may also be an important cause of traveler's diarrhea, especially in Thailand and surrounding areas of Southeast Asia. In a study of American military personnel deployed in Thailand, more than half of those with diarrhea were found to be infected with Campylobacter species.
