- Development of a vaccine for management and control of chlamydial infections in koalas: Chlamydial infection and disease are contributing to a significant decline in the wild koala population in mainland Australia. In collaboration with Australia Zoo and other partners, we are in the process of developing and testing a vaccine, which could be used to prevent the spread of this disease.
- Molecular evolution of Chlamydia pecorum infections in animals, including the koala: Chlamydia pecorum is a bacterial pathogen of sheep and cattle. Our group has previously shown that C.pecorum infections in koalas may have originated from sheep and cattle brought to Australia. With the recent advent of genome sequencing, we plan to investigate the evolution of this bacterial species in Australia.
- Molecular characterisation of Chlamydia-related epitheliocystis agents in wild and cultured fish species: Epitheliocystis is a skink and gill disease of wild and cultured fish species and has long been suspected to be caused by Chlamydia-like organisms. Advances in molecular diagnostics have recently confirmed this link and we are interested in using molecular methods to identify and characterise causative agents of this disease.
