Some Salmonella strains can be nasty bacteria that cause nausea, diarrhoea, vomiting, and other food poisoning symptoms, while others can be relatively harmless.

The new machine learning tool may be useful for flagging dangerous bacteria before they cause an outbreak, from individual hospital wards up to a global scale.

Paper authors Dr Nicole Wheeler and Associate Professor Paul Gardner worked on the research, which formed Dr Wheeler’s 2017 PhD thesis, at UC’s Biomolecular Interaction Centre (BIC), which also funded the research, and UC’s School of Biological Sciences. Dr Wheeler continued her research as a BIC postdoctoral fellow in 2017.

“We have designed a new machine learning model that can identify which emerging strains of bacteria could be a public health concern. Using this tool, we can tackle massive data sets and get results in seconds,” says Dr Wheeler.

“Ultimately, this work will have a big impact on the surveillance of dangerous bacteria in a way we haven’t been able to before, not only in hospital wards, but at a global scale.”

Dr Wheeler, who earned her Bachelor of Science and PhD in Biochemistry degrees at UC, is now a postdoctoral fellow at the Wellcome Sanger Institute in the United Kingdom, one of the world's leading genome centres.

This work was supported by the University of Canterbury, the Biomolecular Interaction Centre, Wellcome, the Alexander von Humboldt Foundation, and a Rutherford Discovery Fellowship administered by the Royal Society of New Zealand.
