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

Bats May Be Animal Reservoir For SARS Virus

Bats are natural reservoirs of SARS-like coronaviruses. Extensive diversity of coronaviruses in bats from China. Crameri says the MERS virus, which also appears to come from a microbat, binds to human cells cironaviruses a different receptor and is less infectious than SARS, but kills a higher percentage of those it infects.

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

Prior to this, only fragments of coronavirus DNA had been found in bats. 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.

Prevalence and genetic diversity of coronaviruses in bats from China.

Bats are natural reservoirs of SARS-like coronaviruses

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. Showing of extracted citations. 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. 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.

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.

Site Navigation Video Audio Photos. Keisuke NakagawaKumari G. 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.

Crameri and colleagues showed that cells from humans, mice and bats, which did not express ACE2, were fo infected by the new viruses but once the cells were modified to express ACE2, the viruses did infect them. Topics Discussed in This Paper.

He was involved in a dars-like of studies that found genetic evidence that cave-dwelling microbats, sold as a food source in wet markets, were harbouring SARS-like coronaviruses.

This site is being redeveloped. He says this is also the first time researchers have been able to isolate a live coronavirus from bats. Muller Applied and environmental microbiology
