Discovery of a novel coronavirus, China Rattus coronavirus HKU24, from Norway rats supports the murine origin of Betacoronavirus 1 and has implications for the ancestor of Betacoronavirus lineage A.

Coronavirus link A decade after the SARS pandemic, scientists have found the strongest evidence to date it originated in bats. Skip to navigation Skip to content. Smith and Ocronaviruses H.

Crameri says the MERS virus, which also appears to come from a microbat, binds to human cells via a different receptor and is less infectious than SARS, but kills a higher percentage of those it infects. Muller Applied and environmental microbiology Showing of extracted citations.

He says this is also the first time researchers have been able to isolate a live coronavirus from bats.

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. 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.


Finding the natural “reservoir” of the SARS virus – a coronavirus – is an important part of being prepared for the future, says Crameri. Maude PaulyJacques B. Skip to search form Skip to main content. 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.

This paper has highly influenced 33 other papers. Extensive diversity of coronaviruses in bats from China. 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.

Here we report that species of bats are a natural host of coronaviruses closely related to those rfservoirs for the SARS outbreak. Site Navigation Video Audio Photos.

Prevalence and genetic diversity of coronaviruses in bats from China. 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.

LokugamageSeiko Makino Advances in virus research From This Paper Figures, tables, and topics from this paper. 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.

Crameri and colleagues showed 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. Bats are natural reservoirs of SARS-like coronaviruses.

Bats are natural reservoirs of SARS-like coronaviruses.

Prior to abts, only fragments of coronavirus DNA had been found in bats. They don’t need any intermediate hosts,” says Crameri. SARS first broke out in “wet markets” in China, which involved the sale of live animals – often from the wild.

Email the editor Share this coronavifuses Email a friend. Walker Methods in Molecular Biology 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.
