rotavirus

[rō′təvī′rəs]

a double-stranded ribonucleic acid virus that appears as a tiny wheel, with a clearly defined outer layer, or rim, and an inner layer of spokes. The virus replicates in the epithelial cells of the intestine and is a cause of acute gastroenteritis with diarrhea, particularly in infants. Rotavirus is the most common cause worldwide of severe diarrheal illness in children, with fecal-oral transmission. Various strains also infect domestic and wild animals. In the United States, infections tend to peak during the winter months. A licensed live virus vaccine is no longer recommended because of its association with a rare case of bowel obstruction (intussusception).

Rotavirus

a genus in the family Reoviridae which cause diarrhea in the young of many species, including avian, but particularly calves, foals, piglets and lambs, particularly in conditions of poor hygiene, crowding and failure of maternal antibody transfer. The morbidity rate is usually very high but death losses are not heavy provided the hydration of the animals is maintained. There is some species specialization but interspecies transmission is common.
