A 3-day-old piglet with diarrhoea was killed, and immunofluorescent microscopic examination of the small intestinal mucosa, together with immune electron microscopic examination of the large intestinal contents, provided a presumptive diagnosis of a concurrent infection with TGE virus and porcine rotavirus. Immunofluorescent microscopic, immune electron microscopic, and serological data obtained from gnotobiotic pigs experimentally inoculated with the large intestinal contents of the piglet confirmed this diagnosis. Two gnotobiotic pigs, convalescent from previous TGE viral infections, became infected with rotavirus only, while another pig which had recovered from rotavirus infection became infected with TGE virus only, following inoculation with the large intestinal contents of the piglet.
