Description
Summary:Coronaviruses (CoV) infect a wide variety of hosts, causing epidemics in humans, birds, and mammals over the years. Bats (order Chiroptera) are one of the natural hosts of the Coronaviridae family. They represent 40% of the total number of mammal species in the Pantanal, a biodiversity hotspot in South America. Given the recent SARS-CoV-2 pandemic, we investigated the presence of CoV in bats captured in the Brazilian Pantanal. Oral and rectal swabs collected in 2021 from 419 bats were analyzed using Pancoronavirus-nested PCR targeting the RNA-dependent RNA-polymerase (RdRp) gene. Orthocoronavirinae was detected in 16.7% (70/419) of the bats; nine samples were sequenced, confirming that <i>Carollia perspicillata</i> (4), <i>Phyllostomus hastatus</i> (2), <i>Desmodus rotundus</i> (1), <i>Molossus rufus</i> (1), and <i>Myotis</i> cf. <i>nigricans</i> (1) collected in buildings formally used by humans were infected by <i>Alphacoronavirus</i> genera. This is the first description of <i>Alphacoronavirus</i> in bats from the Pantanal. As they are natural reservoirs of CoVs, constant monitoring of bats is important to comprehend the epidemiology of emerging viruses, especially in the Pantanal biome.
