reovirus

noun

1. Any of a group of RNA viruses, of the family Reoviridae, that infect animals and some plants

   “The former inclusion of reoviruses in the ECHO group was based originally on their isolation from the stools of human beings, their optimal isolation in monkey kidney tissue culture and the lack of pathogenicity of the initial strains for new-born mice, guinea pigs, rabbits and monkeys.”
