Cultivation and characterization of human rotaviruses with "super short" RNA patterns

Two group A, subgroup I, rotavirus strains possessing "super short" RNA patterns were adapted to growth in MA-104 cells. Both produced marked cytopathic effect in primary culture. Reciprocal cross-neutralization titers, polypeptide analysis, and the serum neutralizing antibody response of an infected child suggested that super short viruses are serotypically distinct from the four recognized human serotypes.
