title: Single and mixed infections of neonatal pigs with rotaviruses and enteroviruses: virological studies.
abstract: Three rotaviruses and three enteroviruses were isolated from pigs with diarrhea. The three enteroviruses and one of the rotaviruses were recovered from pigs infected with both viruses. Separation of rotaviruses and enteroviruses from tissues containing both viruses was effected by pancreatin treatment, terminal dilution, and inoculation onto different cell lines. The three rotaviruses were group A serotype 1, and the enteroviruses were serotypes 2, 3 and 7. Cell culture preparations of these six viruses were inoculated into colostrum-deprived neonatal pigs. All of the rotavirus and enterovirus isolates established intestinal and systemic infection and were shed in the feces after oral inoculation. Concurrent infection with both viruses resulted in only minor alteration of systemic distribution and did not alter fecal shedding of either virus.
