Transmission electron micrograph (TEM) revealed the presence of numerous Reovirus type-3 virions. This virus organism is a member of the family, Reoviridae, genera of which include the Coltivirus, i.e., Colorado tick fever, Orbivirus, i.e., bluetongue virus, and Orthoreovius, within which belong these virions Usually, Reoviridae members cause gastrointestinal and respiratory tract illness, which enables detection in human feces, and sputum samples of infected individuals. However, the virus itself has not been directly linked to any known disease, and therefore, has been categorized as an "orphan" virus. The Reovirus genome consists of segmented, double-stranded RNA (dsRNA) molecules.
