Viable, but non-culturable bacteria: Understanding the risks for food safety
This project aims to determine the ability of viable but non culturable bacteria to cause disease.
Salmonella or Campylobacter species both cause gastrointestinal disease in humans and other mammals. Consumption of contaminated food is the primary source for both bacterial species.
Often, the bacteria may be in a reduced virulence state (viable but non-culturable) in a food item. It is currently not known to what degree these bacteria contribute to causing disease.
- Basic bacteriology of either Salmonella or Campylobacter
- Cell culture for in vitro invasion assays
- Culture of C. elegans
- Fluorescent microscopy
Study pathobiology, infectious disease and public health
Our research is focused on understanding the behaviour of Salmonella and Campylobacter species in the poultry (layer and broiler) farm environment and how these bacteria are able to persist in the food chain.
Another aspect of our work is to understand virulence aspects of both Salmonella and Campylobacter which contribute to human disease.
How do we feed the world’s growing population? How do we save our wildlife from extinction? Got an idea that will build a brighter, greener world?
Australian high school students are invited to submit a short video about one of Australia’s big science challenges.
