The koala，one of Australia's most treasured creatures，is in trouble.
Affected by habitat (栖居地) loss and climate change，like many other unique Australian animals，koalas are being squeezed into smaller regions.But at prent，it is a deadly dia，a somewhat silent killer that caus a further decline in the koala population，that is worrying many scientists about the fate of the koala.
The killer is Chlamydia，which has caud symptoms in up to 50 percent of the wild koalas，with probably even more infected (感染) but not showing symptoms.It has been particularly vere in Queensland，where nearly all koalas are infected.The dia caus many symptoms including eye infections，which can lead to blindness，making it difficult for them to find their primary food.
Treating Chlamydia in wild koalas is a challenge.There is no treatmen我是一颗小小草t available for it．Only a small percentage of the animals can be treated successfully and returned to the wild.Besides，there is no national plan in Australia to save the koala；it is up to each region to make management plans for its koala population.
The good news is that rearchers are working to test a vaccine (疫苗) that would help prevent further spread.If all goes well，plans can be carried out to distribute the vaccine more widely.But it's impossible to vaccinate all wild koalas.
Another possibility would be to make vaccine distribution a routine part of treatment for the thousands of koalas brought into care centers every year after they are injured by cars or dogs.
While it is a combination of problems that are affecting the wild koala population，many experts believe this vaccine would be an important step in helping koalas survive longer.It may buy enough time to give rearchers a chance to solve some of the other problems facing Australia's koalas.
