THE brightest veterinary minds in the country have ruled out flying foxes as the culprit for infecting two horses with Australian bat lyssavirus at Allora.

Chief vets from each state met on Tuesday, to analyse findings on the property and discuss further steps.

Queensland's Chief Biosecurity Officer Jim Thompson said Biosecurity Queensland officers revisited the property and confirmed it was, as suspected, a microbat that infected the horses.

"A number of options for managing the property were considered yesterday by the chief veterinarians," Dr Thompson said.

"Biosecurity Queensland will be discussing these options with the property owner, including isolation and potential vaccination of animals.

The organisations will continue to work closely with property owners in managing the situation.

"Through our understanding of this virus, it is believed that the infected horse was most likely infected through being scratched or bitten by a bat.

"Testing has confirmed the virus in the infected horse was the type of ABLV found in a species of insect-eating microbat, but not in flying foxes."

Dr Thompson said researchers from the Queensland Centre for Emerging Infectious Disease had been conducting property profiling to identify the type of bats and their movements in the area.

"Through their initial work, researchers have identified microbats in the area, including microbats roosting in buildings on the property," Dr Thompson said.

"I must reiterate that we haven't before seen ABLV in a horse in Australia, however, experts from around the country are continuing to work together to learn more about the virus.

"As has been our long-standing advice, it is recommended that animal owners take all reasonable steps to keep their animals away from bats.

"This may include restricting animals at night, particularly when bats are feeding. If owners suspect an animal might have been bitten or scratched by a bat, they should contact their local veterinarian.

"It is also important to ensure sound hygiene and biosecurity measures are routinely adopted for all contact with animals including saliva, blood and other body fluids and associated equipment.

"This is to protect people against a number of diseases that can be transferred, not just ABLV."
