Understanding and combating infectious diseases in koalas

Play Video





1. Please provide a short summary of your research, project or technology.

The long term survival of koalas is under threat and they need our help. Koalas suffer from two major infectious diseases. The first disease is infection with the bacteria Chlamydia, which causes eye infections (leading to blindness) and reproductive and bladder infections (leading to severe pain and infertility). Just like people, some koalas can get Chlamydia and not appear sick. Combining laboratory testing and mathematical models, I am evaluating risk factors to understand why some koalas get very sick. The second major disease is a virus, known as koala retrovirus (KoRV). KoRV appears to weaken the koala’s immune system. I have shown that Queensland koalas with type B KoRV are much more likely to develop chlamydial disease and cancer. I also learned the most common way KoRV was being spread was from mother to joey. This new information is a huge step forward in managing disease in the wild.

Very interesting work Bonnie. I saw the plight of Koalas in an article a couple of years back and added a mention of Chlamydia and Koalas to my introductory microbiology class and then realized you were working on it too. Made it even more interesting. Good luck.

Bonnie, you have been one of the most influential mentors I have had. There are many occasions on certain days when I think how you would do things. Thank you for teaching me science can be fun.
