A gram-negative microaerobic spiral-shaped and non-spore forming bacterium involved as a major causative agent of acute enterocolitis and gastroenteritis in human.


Campylobacter coli has a size of about 0.2-0.9 micrometers wide and 0.5-5 micrometers long which moves like a corkscrew in motion. Pigs and chicken acts as a main host of this bacterium and other animals including sheep and cattle. It can survive in the environment for many weeks in water at 4’C but only days on above 15’C. It is highly versatile bacterium that has a complete citric acid cycle as well as complex respiratory chain that allows both aerobic and anaerobic respiration wherein carbohydrates and amino acids acts as a major carbon source used for growth.

Campylobacter coli is implicated in gastroenteritis and acute enterocolitis as well as in acute diarrheal illnesses manifested with watery diarrhea containing red or white blood cells, abdominal pain, nausea, malaise, vomiting and inflammatory enterocolitis wherein symptoms last for about a week with a relapses. It is pathogenic both in human and animals wherein infections usually happen by eating raw food, raw milk and contaminated bottled water.

Campylobacter coli considered as worldwide prevalence in both develop and developing countries wherein outbreak is most related to food and water-borne vector. Its infection is sporadic that shows seasonal trends in which most cases occurs in late summer and early fall.
