Bat mumps orthorubulavirus, formerly Bat mumps rubulavirus (BMV), is a member of genus Orthorubulavirus, family Paramyxoviridae, and order Mononegavirales. Paramyxoviridaeviruses were first isolated from bats using heminestedPCR with degenerate primers. This process was then followed by Sanger sequencing.[2] A specific location of this virus is not known because it was isolated from bats worldwide. Although multiple paramyxoviridae viruses have been isolated worldwide, BMV specifically has not been isolated thus far.[3] However, BMV was detected in African fruit bats,[4] but no infectious form has been isolated to date.[5] It is known that BMV is transmitted through saliva in the respiratory system of bats. While the virus was considered its own species for a few years, phylogenetic analysis has since shown that it is a member of Mumps orthorubulavirus.[6]
