Map culture results from nine tissue sites processed at necropsy. The data are expressed as the average CFU of triplicate agar cultures containing no hygromycin. No colonies were detected in the agar cultures containing hygromycin, which indicates ΔrelA was cleared in the vaccinated animal. JP, JM, JD: jejunum proximal, middle, distal; IP, IM, ID: ileum proximal, middle, distal; ICV: ileocecal valve; ML, IL: mesenteric and ileocecal lymph nodes. a, Negative; b, too numerous to count; c, Values are expressed as the average CFU obtained from three agar cultures; +, positive by IS900 qPCR.
