The fatal Hendra virus in Australia has jumped to another species.
The virus was previously known to jump from fruit bats, or flying foxes, to horses and humans in New South Wales, the ABC reports.
Biosecurity Queensland says a dog on a property in the state's south east has tested positive to the disease. The kelpie will be put down.
Four people have died of Hendra virus since 1994, and 14 horses in the latest outbreak, which began just over a month ago.
Queensland Premier Anna Bligh says a meeting of a joint Queensland and New South Wales taskforce will be held on Wednesday.
