Double threat to Koala populations in New South Wales and Queensland

Leading vaccine researchers at the University of Queensland (UQ) believe that the Chlamydia epidemic, which endangers koala populations in New South Wales (NSW) and Queensland (QLD), suppresses the sac-like immune system. I have found that it is related to a common retrovirus.

Keith Chapel and Dr. Mikaela Brighton, Associate Professor of Chemistry, Molecular and Biological Sciences, University of Queensland, have studied and discovered more than 150 koalas admitted to the Karambin Wildlife Hospital in Queensland.

so release On Tuesday, the chapel already knew that the koala populations in New South Wales and Queensland were severely affected by chlamydia infections and retroviruses, but so far it has been clear between the two. He said the relevance had not been decisively established.

“According to our research, Retrovirus Circulation in the blood of animals was strongly associated with symptoms such as chlamydia, cystitis and conjunctivitis, as well as deterioration of overall health. “

“It’s a double pain for koalas that are already on the verge of extinction.”

The chapel further stated that high levels of the virus were found to increase the risk of koala chlamydia infection by more than 200%.

“There is no doubt that koala retroviruses are associated with chlamydia. We believe that retroviruses suppress the koala’s immune system and make it more vulnerable to disease,” he said.

Previously it was thought that only certain types of koala retroviruses were likely to cause the disease, but this study reveals that all subtypes are the cause, and these viruses are the koala population. The urgent need to prevent circulation between them has been highlighted.

by Australian Koala FoundationSince 2018, the number of koalas has fallen by an estimated 30% across Australia, reaching 41% in New South Wales and 37% in Queensland.

The devastating wildfires and land reclamation in 2019-20 are the main causes of the sharp decline, Statista Chlamydia also plays a role, saying that many koalas have become infertile and unable to survive in the wild.

Although their findings highlight another threat facing koalas, Dr. Brighton said they could offer new ways to treat populations to stop extinction.

“I am deeply concerned that koalas are facing environmental pressures as well as biological threats from retroviruses and diseases,” she said.

“The results of this study are important for conservation, especially as koalas are now endangered and wild populations continue to decline in Queensland and New South Wales.”

Brighton said the findings will help researchers understand how threats to koalas are related and help protect species, including the use of antivirals and breeding programs. I added.

The UQ team is currently planning to study the effects of environmental factors on the amount of circulating retroviruses and diseases in koala populations.
