Campylobacteriosis  is a bacterial disease (Campylobacter jejuni) associated with diarrhea dogs, cats, calves, sheep, ferrets, and mink, and is a leading cause of diarrhea in humans.  
A similar bacteria, Campylobacter fetus, causes a disease in sheep commonly referred to as ‘Vibrio’ where abortion is the main presenting sign.

How is it transmitted?  The disease is most commonly spread by fecal contamination of food and water sources of both animals and people. Apparently healthy animals can shed the bacteria in their feces for long periods. Unpasteurized milk is another source of infection.

What are the signs in animals? Young animals are most severely affected and develop fever, diarrhea, colic, dehydration, and may die if not treated appropriately.
‘Vibrio’ can cause late abortions, stillbirths, and weak lambs.

Dehydrated calf
Dehydration, diarrhea, and fever are common signs of a calf with Campylobacteriosis
What are the symptoms in humans? Most people develop diarrhea,  abdominal pain, and fever within 2 to 5 days after exposure to the organism. The diarrhea may be bloody and can be accompanied by nausea and vomiting.
