The pathogenic potential of human rotaviruses of serotypes 1 through 4 was evaluated in suckling mice. Oral inoculation of three different human rotaviruses of serotype 3 into 5-6 day old CD-1 mice caused disease characterized by diarrhea and dehydration. The mean 50% diarrhea inducing dose (DD50) was 5 X 10(5) pfu. Histopathological examination of small intestines revealed villus epithelial cell vacuolization localized to the distal one-third of the villus. Only Serotype 3 rotaviruses exhibited a rapid phase of viral growth in the intestine between 7 and 12 hours post-inoculation. Larger inocula of rotavirus serotypes 1, 2, and 4 did not cause disease or typical histopathologic changes. However, immunoperoxidase staining for rotavirus antigen was positive in all serotypes tested indicating that infection can occur without apparent disease and is not serotype specific. This convenient in-vivo model can be used to evaluate attenuation of human origin vaccine candidates of serotype 3.
