摘要

A survey was carried out in search for bat coronaviruses in an urban maternity roost of about 500 specimens of two species of insectivorous bats, and in Southern Brazil. Twenty-nine out of 150 pooled fecal samples tested positive by reverse transcription-PCR contained fragments of the RNA-dependent RNA polymerase gene of -related viruses. The sequences clustered along with bat alphacoronaviruses, forming a subcluster within this group. Our findings point to the need for risk assessment and continued surveillance of coronavirus infections of bats in Brazil.
