Many paramyxoviruses are responsible for a variety of mild to severe human and animal diseases.Based on the novel discoveries over the past several decades,the family Paramyxoviridae infecting various hosts across the world includes 4 subfamilies,17 classified genera and 78 species now.However,no systematic surveys of bat paramyxoviruses are available from the Chinese mainland.In this study,13,064 samples from 54 bat species were collected and a comprehensive paramyxovirus survey was conducted.We obtained 94 new genome sequences distributed across paramyxoviruses from 22 bat species in seven provinces.Bayesian phylodynamic and phylo-genetic analyses showed that there were four different lineages in the Jeilongvirus genus.Based on available data,results of host and region switches showed that the bat colony was partial to interior,whereas the rodent colony was exported,and the felines and hedgehogs were most likely the intermediate hosts from Scotophilus spp.rather than rodents.Based on the evolutionary trend,genus Jeilongvirus may have originated from Mus spp.in Australia,then transmitted to bats and rodents in Africa,Asia and Europe,and finally to bats and rodents in America.
