Introduction

Reoviridae include rotaviruses and orbiviruses, such as African Horse Sickness and Bluetongue. Pathogenesis ranges from acute alimentary infections to infections of the vascular endothelium. "REO" stands for "Respiratory-Enteric-Orphan."

Morphology

• All are non-enveloped dsRNA viruses
• Spherical and medium-sized with characteristic appearances
• Segmented genome, with each segment encoding a separate viral protein

Virulence and Pathogenesis

• Reoviridae are resistant viruses that can persist in the environment for several weeks

Epidemiology

• Many reoviruses infect domestic animals without causing disease
• They have been implicated in stunting syndrome of chickens
