A team of mostly Chinese researchers report today in the journal Nature they have isolated two new viruses that are closely antural to the SARS virus.

Bats are natural reservoirs of SARS-like coronaviruses.

Prevalence and genetic diversity of coronaviruses in bats from China. From This Paper Figures, tables, and topics from this paper. 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. Extensive diversity of coronaviruses in bats from China.

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.

This site is being redeveloped. LokugamageSeiko Makino Advances in virus research Here we sags-like that species of bats are a natural host of coronaviruses closely related to those responsible for the SARS outbreak.

Walker Methods in Molecular Biology 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.

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

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. Keisuke NakagawaKumari G. Showing of extracted citations.

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. Muller Applied and environmental microbiology 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.

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. For all the latest ABC Science content click here. Coronavirus link A decade after the SARS pandemic, scientists have found the strongest evidence to date it originated in bats.

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