Dr Natasha Speight is a lecturer at the School of Animal and Veterinary Sciences and is a registered veterinarian. Her current research focuses on the biology, health and diseases of South Australian populations of koalas, particularly oxalate nephrosis.

Chlamydial disease in koalas is devastating populations of koalas on the east coast of Australia. Our research has shown that Chlamydial infection is common in koalas in the Mount Lofty Ranges of South Australia, but causes little disease in these koalas (Speight et al, 2016; Fabijan et al, 2019a). Kangaroo Island koalas have been shown to be Chlamydia pecorum- free, making them a large isolated population of negative koalas (Fabijan et al, 2019a). Koala retrovirus infects many South Australian koalas (Fabijan et al, 2019b), but research is continuing to understand the impact on koalas (Sarker et al, 2019). Mount Lofty Ranges koalas are also affected by sarcoptic mange, caused by a mite that burrows into the skin causing crusty lesions (Speight et al, 2017), and oxalate nephrosis, a disease in which calcium oxalate crystals are deposited in the kidneys leading to renal dysfunction (Speight et al, 2013;2014). The cause of oxalate nephrosis is under investigation for the contribution of various factors including dietary oxalate (Speight et al, 2013), climate (Speight et al, 2018) and gut bacteria (Speight et al, 2019).
