Campylobacter coli is a Gram-negative bacterial species within genus Campylobacter.
At least a dozen species of Campylobacter have been implicated in human disease (campylobacteriosis), with C. jejuni and C. coli the most common. In humans, 85% to 95% of infections by the Campylobacter species involve C. jejuni, while C. coli is involved in a majority of the other cases.
The bacterium is often found in pigs but can also infect humans and a wide range of animals such as cattle, sheep, and bird.
Similar to the C. jejuni, C. coli has the ability to cause enteritis with symptoms such as abdominal pain, diarrhea, bloody stool, vomiting and fever. These symptoms are caused, in part, by a secreted cytolethal distending toxin.
