Summary
Campylobacter jejuni is the leading cause of foodborne illness within Australia. To improve food safety there is a critical need for new therapeutics and diagnostics that target this agent. Within nature bacterial viruses possess proteins that can perform such a task. By using mass spectrometric analysis we aim to exploit billions of years of co-evolution to identify bacterial viral proteins that bind C. jejuni to identify novel means to limit and lower C. jejuni numbers in food sources.
The Role Of N-linked Protein Glycosylation In Campylobacter Jejuni Pathogenesis

Summary
Protein glycosylation is crucial in enabling C. jejuni to colonize poultry, which is the most common route to human infection. The roles played by this modification remain almost completely unknown yet are likely to be multi-factorial. This project will determine the function of glycosylation and thus lead to eventual interventions aimed at reducing the organism in poultry for human consumption.
Understanding The Role Of O-linked Glycosylation In Burkholderia Cenocepica For Host Survival Using Proteomic Approaches

Summary
The bacteria Burkholderia cenocepecia (Bc) is a common infection of Cystic Fibrosis suffers in Australia. ~20% CF patients infected with Bc will die due to lung failure. Due to this high death rate there is an urgent need to understand how Bc survives and causes disease in the host. This grant aims to understand how the attachment of sugars, a process known as glycosylation, affects the ability of Bc to survive in mammalian cells.
Glycosyltransferase Effectors Of Enteropathogenic E. Coli And Salmonella

Summary
This project aims to characterise the mechanisms of disease caused by bacterial pathogens including Salmonella and enteropathogenic E. coli. These pathogens cause a significant amount of diarrhoeal disease and mortality worldwide particularly in infants and in countries where water sanitation is poor. I aim to investigate the specific mechanisms the bacteria employ to manipulate and avoid our immune response during infection in order to better understand and combat diarrhoeal disease.
Phase Variable Protein Glycosylation In Bacteria Mucosal Pathogens And Its Role In Immune Evasion

Summary
The bacterium Haemophilus influenzae is a leading cause of ear infections. Hearing loss from these infections can seriously affect literacy and educational performance. As no vaccine is available, we will research how the bacterium makes the HMW protein that is important in infection. We will study how sugars are added to the surface of this protein so that the bacterium can escape the immune system, its role in related bacteria and how it may be used in a vaccine.
