It was nice to be reunited with my fellow countryman when I was so far from home! He looked about as glamorous as I do first thing in the morning, it must be the Australian charm..
He had a troublesome weepy eye, and since he is a koala, an important differential for this is Chlamydia. Yes, it's true that koalas commonly suffer from Chlamydia, which is a bacterial infection that can present as ocular, urinary or reproductive disease. In fact, Australia is facing a koala Chlamydia epidemic, with infection rates as high as 90% in some areas. On top of this, a retrovirus similar to HIV in humans is also spreading through the population, resulting in a suppressed immune system and high fatality rates from secondary lymphoma and leukaemia. Our koalas are now classified as endangered in three states, and there is even some speculation that they could face extinction if this trend continues. However, a vaccine trial for the treatment of infected koalas has just begun in Australia, so fingers crossed for its success against this horrible disease!
