Since these SARS-like viruses do not bind to ACE2, this made researchers wonder whether SARS really came from sags-like, 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. Bats are natural reservoirs of SARS-like coronaviruses.

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
Prior to this, only fragments of coronavirus DNA had been found in bats. Topics Discussed in This Paper.
Viral Zoonoses That Fly with Bats: Email the editor Share this article Email a friend. LokugamageSeiko Makino Advances in virus research But coornaviruses viruses differed from SARS, particularly in the region of the virus that binds to a host protein called ACE2, facilitating infection, says Crameri. This paper has highly influenced 33 other papers. This site is being redeveloped. Coronavirus link A decade after the SARS pandemic, scientists have found the strongest evidence to date it originated in bats.
They don’t need any intermediate hosts,” says Crameri.
Humans are mainly exposed to viruses from bats via the animals’ faeces, says Crameri, adding that stress in the animals appears to increase this shedding. Finding the natural “reservoir” of the SARS virus – a coronavirus – is an important part of being prepared for the future, says Crameri. Here we report that species of bats are a natural host of coronaviruses closely related to those responsible for the SARS outbreak.
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.

Discovery of a novel coronavirus, China Rattus coronavirus HKU24, from Norway rats supports the murine origin of Betacoronavirus cooronaviruses and has implications for the ancestor of Betacoronavirus lineage A. 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.
Prevalence and genetic diversity of coronaviruses in bats from China. Bats are an ancient animal that diverged from 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. The researchers also found that the new viruses also had exactly the same proteins used ntaural the SARS virus to bind to ACE2 in host cells.
