Rotavirus

Rotaviral diarrhea is caused by a double-stranded RNA, non-enveloped virus of the family Reoviridae, genus Rotavirus. This virus is one of the most common causes of foal diarrhea in horse breeding centers around the world. Infectivity and severity of disease generally decline with increasing foal age. It is not considered to be a cause of diarrhea in horses over the age of six months.

Fecal samples should be submitted for both virus and bacteriological testing. Consult laboratory for testing capabilities and sample/shipping requirements prior to submitting samples. In general, the minimum sample is 1-3 grams of feces. It is best to obtain fresh fecal samples (free catch or rectal.)
