Campylobacter jejuni is a species of bacteria commonly found in animal feces. It is curved, helical-shaped, non-spore forming, Gram-negative, and microaerophilic.[1][2][3] C. jejuni is one of the most common causes of human gastroenteritis in the world. Food poisoning caused by Campylobacter species can be severely debilitating, but is rarely life-threatening. It has been linked with subsequent development of Guillain-Barré syndrome (GBS), which usually develops two to three weeks after the initial illness.[4]
