Campylobacter jejuni

Campylobacter jejuni is a species of curved, helical shaped, non-spore forming, Gram-negative microaerophilic, bacteria commonly found in animal feces. It is one of the most common causes of human gastroenteritis in the world. This food poisoning can be severely debilitating but rarely life-threatening. It has also been linked to Guillain-Barre syndrome which generally develops two to three weeks after the initial illness.

It is commonly associated with poultry, and it naturally colonizes the digestive tract of many birds. It has also been found in wombats and kangaroo feces. Contaminated drinking water and un-pasteurized milk provide an efficient means for distribution.

Infection often results in enteritis which results in abdominal pain, diarrhea, fever, and malaise. Symptoms persist for between 24 hours and a week but can last longer. The disease does respond to antibiotics, typically ciprofloxacin. Fluid and electrolyte replacement are necessary in serious cases.
