Campylobacter jejuni associated diarrhea in commercially reared beagles.

Campylobacter jejuni was isolated from nine of ten (90%) juvenile beagles with diarrhea, compared with an isolation rate of five of eight (63%) from beagles which remained asymptomatic during the 2 month study. In four dogs, the diarrhea was recurrent and characterized by watery, mucoid, bile-streaked feces with occasional blood. Elevated temperature and leukocytosis were noted in three of these dogs. Two dogs with diarrhea also had Giardia canis trophozoites.
