Reovirus-associated enteritis in Georgia broiler chicks.

The histopathology of reovirus-infected small intestines from clinically ill commercial broiler chicks afflicted with so-called runting stunting syndrome is described. We do not speculate that a cause-and-effect relationship necessarily exists between intralesional reovirus and illness in chicks in the present study. We propose that, in the future, similar cases be termed reovirus-associated enteritis (RAE). RAE must be differentiated from lesions attributed to infections by enterovirus-like particles.
