title: Concurrent porcine rotaviral and transmissible gastroenteritis viral infections in a three-day-old conventional pig.
abstract: A 3-day-old suckling pig with diarrhea was necropsied, 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 transmissible gastroenteritis (TGE) virus and porcine rotavirus. Immunofluorescent microscopic, immune electron microscopic, and serologic data obtained from gnotobiotic pigs experimentally inoculated with the large intestinal contents of the suckling pig confirmed this diagnosis. Two gnotobiotic pigs, convalescent from previous TGE viral infections, became infected with porcine rotavirus only. However, another gnotobiotic pig, convalescent from a previous porcine rotaviral infection, became infected with TGE virus only, following inoculation with the large intestinal contents of the suckling pig.
