Associate Professor Michelle Power discusses her expertise in
the study of
host-parasite associations in wildlife, with particular
emphasis on protozoan parasites.
Tune in to discover:
- What differentiates the two main classes of resistant bacteria and why this has important implications for humans, and potentially wildlife
- Why it is important to think about the many interactions within organisms relative to disease (i.e. the context of coinfection) rather than thinking about only about one host and one pathogen at a time
- What important ecological role flying foxes play in Australia
The flying fox (i.e. fruit bat) is one of the world’s largest bats, and in Sydney, Australia, thousands of them can be found hanging from the trees in even the most urbanized parts of the city. Most of us are familiar with the idea that viruses can be transferred from these and other animals to humans, but what can be said about how the process might work in the opposite direction? In other words, what types of parasites and bacteria may be picked up by bats and other wildlife as the result of humans in their environment?
These questions involve the concept of reverse zoonosis, which
comprises one of Power’s primary research interests. She and the
research team in the biology department at Macquarie University
work on a suite of different organisms, most of which are
associated with the gut, such as cryptosporidium and giardia. Both
of these parasites are transmissible through the water and can
therefore travel through the environment.
As a result, they can be picked up by wildlife through drinking
water or through interactions during rehabilitation and/or
long-term captivity. Power is also researching
malarial parasites and antibiotic-resistant bacteria, a global
health concern for humans that may or may not be making its way
into wildlife.
