It is the first bat reovirus isolated in China. The preparation is tested for absence of HIV, HCV, herpes virus, and reovirus. They are also exploited by viruses such as Polio and Reovirus for dissemination. NBV was the first reovirus to be isolated from a bat species. There is currently only one species in this genus&colon; the type species "Eriocheir sinensis reovirus". McClain and Spendlove demonstrated MR for three types of reovirus after exposure to ultraviolet irradiation. Some disease-causing reovirus species are associated with bats. Such a regeneration phenomenon, known as multiplicity reactivation, occurs in influenza virus and reovirus. Reovirus infection occurs often in humans, but most cases are mild or subclinical. "Eriocheir sinensis reovirus" was isolated out of a Chinese mitten crab ("Eriocheir sinensis"). Piscine reovirus is a Spinareovirinae-like virus that has not yet been classified. In particular, reovirus has eight structural proteins and ten segments of dsRNA.
