FIGURE 4

Live attenuated duck enteritis virus (DEV) vaccine replicated in non-target chickens and resulted in effectively virus transmission. (A) Pathogenic lesions of non-target chickens. (B) The hematoxylin- and eosin (H&E)-stained tissue section in non-target chickens. From left to right are liver, heart, spleen, glandular stomach, liver, kidney, and intestine. (C) The survival curve of non-target chickens. (D) DEV effectively replicates in different tissue of non-target chickens. Data are representative of four experiments related to challenge. **P < 0.01, ***P < 0.001, and ****P < 0.0001.
