Experimental design. Chicks were divided into each of three different conditions: APEC challenge status, tissue harvest time, and pathology level. Based on the severity of lesions in liver, pericardium, and air-sac scored at necropsy, the challenged birds were assigned to either mild or severe pathology categories, representing resistant and susceptible phenotypes, respectively. Birds in six treatments total were studied: day 1 resistant, day 1 susceptible, day 5 resistant, day 5 susceptible, day 1 non-infected, and day 5 non-infected
