Research focus on animal viruses

STAFF REPORTERThe West Australian

Recent global events highlight the need to ramp up research into viruses that spread from animals to humans, says a biosecurity expert.

In Canberra today CSIRO biosecurity flagship director Gary Fitt said 70 per cent of new diseases in people originated in animals.

"We are lucky to have a strong biosecurity system, backed by world-class science, but we live in an increasingly connected world with trade and people movements putting us at greater risk," Dr Fitt said.

Just recently a new SARS-like virus has emerged from the Middle East and has already killed 45 of 82 people infected since September 2012.

While in China right now there is a new strain of highly pathogenic bird flu, known as H7N9, which is spreading undetected, killing people instead of chickens, yet it is still unknown how it spreads, he added.

CSIRO and Duke-NUS (an alliance between Duke University in North Carolina, USA and the National University of Singapore) have signed a relationship agreement with a view to forming the International Collaborative Centre for One Health to assist in taking a new approach to tackling these deadly viruses.

Dr Linfa Wang, CSIRO Science Leader and Director of the Program in Emerging Infectious Diseases at Duke-NUS, said that responding to these emerging threats needs a different approach to the past and must integrate medical, veterinary, ecological and environmental research.

"Bringing all of these disciplines together to develop a One Health approach rather than working independently is what our new international partnership is all about," he said.

"We are combining CSIRO's world-leading bat virology research with Duke-NUS medical expertise in the development of new and more effective methods for the discovery, treatment, prevention and control of new and emerging diseases in people."

Research is already underway with the team at Duke-NUS working to develop new tests for early and rapid detection of emerging infectious diseases, such as Hendra virus and coronaviruses.

CSIRO scientists with expertise in bat virology will then test and validate these new platforms at the Australian Animal Health Laboratory, the world's most advanced high containment facility, located in Geelong Victoria.

This work builds on CSIRO's biosecurity research, including the delivery of a biological control for one of the world's most invasive pests - the silverleaf whitefly - and the recent development of an equine Hendra virus vaccine.
