Our research relates to Campylobacter and Clostridium difficile infections. Both are infections that cause gastroenteritis and involve organisms that occur in a range of different animals as well as humans. Campylobacter infections are typically acquired through eating food that has been contaminated with Campylobacter, although people can also get the infection from their pets and (rarely) from other people in their household who are infected. While we know quite a bit about the different foods that are risky for Campylobacter infection, we need more evidence in order to try and reduce the risk of getting the infection from food. In addition, we know very little about this infection in low and middle income settings, where other factors may be important.

Clostridium difficile is more complicated. It is widely spread in the environment as it can create hardy long-lasting spores that are resistant to many disinfectants. Clostridium difficile can be transmitted between people in the hospital or home setting but there is some evidence that people may also acquire the infection from other sources such as eating contaminated food or working with contaminated soil. There is strong circumstantial evidence of this but it is still not clear whether or not this form of transmission occurs in Australia.
