A latest research statement from Australian national science body, CSIRO, has confirmed on Thursday that the Severe Acute Respiratory Syndrome (SARS) virus which killed hundreds people originated in horseshoe bats from China, according to a statement released Thursday.

According to the statement, the international research team, led by Professor Shi Zhengli from Wuhan Institute of Virology, Chinese Academy of Sciences and including CSIRO and Duke-NUS scientist Professor Linfa Wang, have just had their breakthrough results published in the journal Nature.

The figures of the statement showed the Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) pandemic killed 774 people of the 8094 people infected, a case fatality ratio of almost 10 percent. With cases diagnosed across the world, the pandemic had an impact on international travel and trade.

This team successfully isolated a SARS-like CoV, named SL-CoV WIV1, directly from faecal samples of Chinese Horseshoe bats using the world renowned bat virus isolation methodology developed by scientists at CSIRO's Australian Animal Health Laboratory in Geelong, Victoria.

While researchers globally have previously used genetic sequencing to demonstrate that bats are the natural reservoirs of SARS-like CoVs, this is the first time that live virus has been successfully isolated from bats to definitively confirm them as the origin of the virus, scientists confirmed on Thursday.

"The results will help governments design more effective prevention strategies for SARS and similar epidemics," the statement said.

Horseshoe bats are found around the world, including Australia and play an important ecological role. Their role in SARS-CoV transmission highlights the importance of protecting the bat's natural environment so they are not forced into highly populated urban areas in search of food.
