Bats in Laos caves found to carry coronaviruses that share key feature with Sars-CoV-2

VIENTIANE, Sept 18 (Bloomberg): Bats dwelling in limestone caves in northern Laos were found to carry coronaviruses that share a key feature with SARS-CoV-2, moving scientists closer to pinpointing the cause of Covid-19.

Researchers at France’s Pasteur Institute and the University of Laos looked for viruses similar to the one that causes Covid among hundreds of horseshoe bats. They found three with closely matched receptor binding domains -- the part of the coronavirus’s spike protein used to bind to human ACE-2, the enzyme it targets to cause an infection.
