Abstract

A novel group 1 coronavirus was previously identified in bent-winged bats ( spp.). Here, results are described from our ongoing surveillance of these bats for coronaviruses. These findings show that group 1 coronaviruses are endemic in these bat populations in Hong Kong. Genetic analysis of these viruses indicates that there are at least four different, but closely related, group 1 coronaviruses (bat-CoV 1A, 1B, HKU7 and HKU8) circulating in bent-winged bats. Phylogenetic analysis revealed that these group 1 bat coronaviruses have descended from a common ancestor and that these viruses have been established in these bats for a long period of time. These data provide a better understanding of the emergence and evolution of coronaviruses. Bat-CoV 1A and 1B were detected in apparently healthy and , respectively, on repeated sampling occasions at a single habitat, suggesting that these viruses have established a persistent infection in these populations.
