Experimental chick colonization by Campylobacter jejuni.

Campylobacter jejuni is commonly isolated from animals, including rodents, farm animals, and especially birds. The most common route of infection for humans is through the ingestion of contaminated chicken. Although C. jejuni commonly inhabits a number of animals, it does so asymptomatically. Many animals have been explored for use in pathogenic models; however, the most commonly used and established animal model is the chick colonization model described in this unit.
