rotavirus

 [ro´tah-vi″rus]
any member of a genus of reoviruses that have a wheellike appearance; they are transmitted by the fecal-oral route and cause acute gastroenteritis and diarrhea in infants and young children. There are 6 different antigenic groups.

ro·ta·vi·rus

(rō'tă-vī'rŭs),
A group of RNA viruses (family Reoviridae) wheellike in appearance, which comprise a genus, Rota virus, which includes the human gastroenteritis viruses (a major cause of infant diarrhea throughout the world). Separated into groups A-F, rotaviruses can infect a number of vertebrates. They are fastidious, and in vitro culture is difficult.
[L. rota, wheel, + virus]

Rotavirus

/Ro·ta·vi·rus/ (ro´tah-vi″rus) rotaviruses; a genus of viruses of the family Reoviridae, having a wheel-like appearance, that cause acute infantile gastroenteritis and cause diarrhea in young children and many animal species.

rotavirus

(rō′tə-vī′rəs)
n. pl. rotavi·ruses
Any of a genus of wheel-shaped reoviruses, including one that causes gastroenteritis, especially in infants and newborn animals.

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 (rō´təvī´rəs),

n a double-stranded ribonucleic acid molecule that appears as a tiny wheel, with a clearly defined outer layer or rim and an inner layer of spokes. It is a cause of acute gastroenteritis with diarrhea, particularly in infants.

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.
