title: The experimental infection of piglets with a porcine reovirus.
abstract: A strain (Quebec) of reovirus isolated from the faeces of a pig with dysentery was neutralised by reovirus type 1 antiserum. Four of eight hysterectomy-produced, colostrum-deprived (HPCD) piglets dosed orally with the third cell culture passage of the virus developed diarrhoea and showed focal areas of villous atrophy in the small intestine. The virus was isolated from the intestinal tract of all eight specific pathogen free piglets, but not from three control animals. Nine germ-free piglets dosed orally with the eight cell culture passage of the virus showed neither clinical signs nor lesions, but virus was recovered from their intestinal tracts for 14 days after infection. No virus was isolated from four control germ-free piglets.
