US GS study: big brown bats are not susceptible to SARS-CoV-2

To help determine the impacts of the pandemic virus on North American bat populations, authors experimentally challenged big brown bats (Eptesicus fuscus) with SARS‐CoV‐2 under BSL‐3 conditions. They inoculated the bats both oropharyngeally and nasally, and over the ensuing three weeks we measured infectivity, pathology, virus concentrations in tissues, oral and rectal virus excretion, virus transmission, and clinical signs of disease.  No evidence of SARS‐CoV‐2 infection in any examined bat, including no viral excretion, no transmission, no detectable virus in tissues, and no signs of disease or pathology was found.
