Interactions between rotavirus and gastrointestinal cells.

Rotaviruses are the leading cause of life-threatening diarrheal disease in infants and in young animals worldwide. The outcome of rotavirus infection of intestinal epithelial cells is more complex and involves induction of more diverse cellular responses than initially appreciated. Similar to bacteria, the pathogenesis of rotavirus-induced disease involves an enterotoxin, activation of the enteric nervous system and malabsorption, suggesting that common mechanisms of pathogenesis may exist between viral and bacterial pathogens.
