Black rats in the largest Australian cities have developed a genetic mutation that enables them with greater resistance to one of the most commonly used poisons. Research Lead Alice Gorbould from the Edith Cowan University, revealed this mutation in more than half of the rats tested in the four largest Australian city between 2021. and 2024. Years.
This mutation indicates the development of rat resistance to other generation anticoagulant rodenticides (SGA), while other animals continue to die from these poins. SGARs are especially dangerous for predators such as brown Žaboustih owls, Australian Boobook owls and eastern cousers, which feed on rodents. Experts warn that the increased red race resistance, the most common types of rats in Australia, could represent a serious threat to the Australian wilderness. Gorbould express concern about the potential public health crisis, as the Australians could reach out for larger amounts of poison in trying to solve the rats problem, passes Evening.
However, such an approach would only lead to further penetration of the food chain and water flows. Animals that consume these anticoagults die from internal bleeding. The research revealed the genetic mutation of Tyr25phe, associated with resistance to these poisons, in 53.7% of the tested rats. Testing spent on 191 rats in the four most populous Australian city showed alarming results: Gene was found in more than 80% of black rats in Perth, more than 45% in Sydney, 39% in Melbourne, while in Brisbane, he was not detected.
– The use of ineffective baits can lead to increased use of poison – the Gorbould for Daily Mail Australia warned.
– This creates a vicious circle of increasing the resistance of the population of rats, non-movable poisoning and potential public health problems due to uncontrolled rats – She added.
