Muller Applied and environmental microbiology 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.

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. Finding the natural “reservoir” of the SARS virus – a coronavirus – is an important part of being prepared for the future, says Crameri.

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.

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. Site Navigation Video Audio Photos. 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.

Now that animals, including bats, and humans live closer together as our population expands globally, the opportunity for direct transmission of these dangerous resercoirs becomes more and more of an issue.


They don’t need any intermediate hosts,” says Crameri. From This Paper Figures, tables, and topics from this paper. 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.

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. Topics Discussed in This Paper. 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.

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.

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. While civet cats were first thought to be the reservoir, researchers soon discovered that these animals were only infected around markets.
