Since these SARS-like viruses do not bind to ACE2, this made researchers wonder whether SARS really came from bats, or whether it needed an intermediate host to convert the virus into a form that could infect humans.

SARS first broke out in “wet markets” in China, which involved the sale of live animals – often from the wild. Here we report that species of bats are a natural host of coronaviruses closely related to those responsible for the SARS outbreak.

They don’t need any intermediate hosts,” says Crameri. By clicking accept or continuing to use the site, you agree to the terms outlined in our Privacy PolicyTerms of Serviceand Dataset License. Prior to this, only fragments of coronavirus DNA had been found in bats. Now that animals, including bats, and humans live closer together as our population expands globally, the opportunity for direct transmission of these dangerous viruses becomes more and more of an issue.

Bats May Be Animal Reservoir For SARS Virus

Bats are natural reservoirs of SARS-like coronaviruses. A team of mostly Chinese researchers report today in the journal Nature they have isolated two new viruses that are closely related to the SARS virus. Finding the natural “reservoir” of the SARS virus – a coronavirus – is an important part of being prepared for the future, says Crameri.

Crameri and colleagues coronavirues that cells from humans, mice and bats, which did not express ACE2, were not infected by the new viruses but once the cells were modified to express ACE2, the viruses did infect them.

Crameri says the MERS virus, which also appears to come from a microbat, bzts to human cells via a different receptor and is less infectious than SARS, but kills a higher percentage of those it infects. But the viruses differed from SARS, particularly in the region of the virus that binds to a host protein called ACE2, facilitating infection, says Crameri.

The researchers also found that the new viruses also had exactly the same proteins used by the SARS virus to bind to ACE2 in host cells. Maude PaulyJacques B.

Bats are an ancient animal that diverged teservoirs other mammals 80 million years ago and Crameri says this could explain why they carry a high number of pathogens that they themselves are unaffected by. Skip to navigation Skip to content.

Smith and Jonathan H. He says this is also the first time researchers have been able to isolate a live coronavirus from bats. He was involved in a number of studies that found genetic evidence that cave-dwelling microbats, sold as a food source in wet markets, were harbouring SARS-like coronaviruses.
