Abstract

Chickens infected with avian pathogenic Escherichia coli (APEC) have reduced production and livability. Gene expression in response to APEC infection was assessed in 4 genes; interleukin-1β (IL-1β), IL-6, IL-10, and Granzyme A (Gzm A). Differences in expression were deduced between challenged and non-challenged birds, and between birds with a mild and severe response to infection. These genes may be useful candidates for future research into breeding for resistance against APEC.
