Intestinal damage in suckling piglets infected with rTGEV-SPEDV viruses. (A) Representative hematoxylin-eosin-stained front sections from non-infected animals (mock), or animals infected with rTGEV-SPEDV or rTGEV-RS-SPEDV viruses, at six days post-infection. Pictures were obtained with a 2.5× objective. (B) Villous height to crypt depth (VH/CD) ratio in front, middle, and end sections at different days post-infection. Non-infected animals (black), or animals infected with rTGEV-SPEDV (blue) or rTGEV-RS-SPEDV (red) viruses. Represented values are the mean from three independent animals, two fields per section. Error bars represent the standard deviation for each value; p values, ** <0.01, *** <0.001.
