On the Trail of Campylobacter - The Campylobacter is one of the leading causes of human gastroenteritis. Common Campylobacter species C. jejuni, C. coli, and C. lari are responsible for most cases of campylobacteriosis. However, other species, like C. fetus, which causes spontaneous abortions, have also been associated with human illness. Campylobacter are Gram-negative, spiral-shaped, microaerophilic and motile bacteria with uni- or bi-polar fl agella
