Miniopterus Bat coronavirus 1 is a novel enveloped, single-stranded positive-sense RNA virus species in the Alphacoronavirus, or Group 1, genus with a corona-like morphology. It causes severe acute respiratory syndrome in bats. Isolates have not been found in humans.

Reservoir
The Miniopterus bat is a bent-winged bat found throughout Asia and the Middle East. Isolates of Miniopterus Bat CoV-1 have not been found in humans. Bat-CoV-1A and 1B have been also isolated from Miniopterus magnater and Minipterus pusillus in Hong Kong. Phylogenetic analysis revealed that these group 1 bat coronaviruses have descended from a common ancestor. The four different but closely related group 1 alphacoronaviruses (bat-CoV 1A, 1B, HKU7 and HKU8), have been isolated from otherwise healthy bats which suggests that these viruses are well established in these species.
Transmission
Transmission of Miniopterus Bat CoV-1 within the species is believed to be through droplet-respiration from contaminates of saliva and excreta. There is also evidence of interspecies transmission of coronavirus among bats.
Genome
All the Alpha and betacoronaviruses, Group 1 and Group 2, are derived from the bat gene pool. There are at least four different, but closely related, Alphacoronaviruses (bat-CoV 1A, 1B, HKU7 and HKU8) circulating in bent-winged bats. Coronaviruses in bats are descended from a common ancestor and have been evolving in bats over a long period of time.
A significant percentage of newly emerging viruses are RNA viruses. It is believed this is due to the fact that RNA viruses have a much higher nucleotide mutation rate than DNA viruses.
