Abstract
Summary
Three immunologically unrelated enterovirus-like agents, antigenically unrelated to any of the recognized human prototypes were isolated from stool specimens of patients suffering from bacillary dysentery in Mexico City in 1957. The viruses were not pathogenic for suckling mice nor for cultured cells of human origin. Indirect evidence based on antibody studies would indicate that 2 of these viruses may belong to the human enterovirus group. The relationship of these agents to the clinical disease observed remains undetermined.
