MOESM19 of Development of a live attenuated trivalent porcine rotavirus A vaccine against disease caused by recent strains most prevalent in South Korea

Additional file 19. Histopathological changes in the small intestine of piglets inoculated with a porcine live attenuated monovalent rotavirus strain (K71V-80) and its serial passages. (A–E) Duodenum sampled from piglets inoculated with each of the serial passaged viruses demonstrated normal long slender villi and short crypts in the mucosal membrane. (F–J) Jejunum sampled from piglets inoculated with each of the serial passaged viruses demonstrated normal long slender villi and short crypts in the mucosal membrane. (K–O) Ileum sampled from piglets inoculated with each of the serial passaged viruses demonstrated normal long slender villi and short crypts in the mucosal membrane. Bar = 200 μm
