Enteroviruses Reoviruses

Routine cell culture of human feces will frequently show reoviruses and enteroviruses (including polio-virus, echoviruses, coxsackieviruses) excreted by patients with and without diarrhea. Most are coincidental infections, unrelated to an etiology of diarrhea, but there is evidence implicating group A coxsackieviruses and echoviruses types 11 and 18 as causes of diarrhea in normal and in immunodeficient patients. Reoviruses can produce diarrhea in animals, including mice, where the intestine is a portal of entry for systemic infection.
