Summary
Bacterial infectious diseases are a serious threat to human health, accounting for over 10 million deaths each year. This multidisciplinary collaborative team is investigating the complex interactions between major disease-causing bacteria and their human hosts, in order to determine how they cause disease. These studies will make a major contribution to fundamental knowledge in this field.

This multidisciplinary collaborative team is investigating the complex interactions between major disease-causing bacteria and their human hosts, in order to determine how they cause disease. These studies will make a major contribution to fundamental knowledge in this field. This information is also essential for the development of cheaper and more effective vaccines, as well as novel drugs. These are urgently needed to reduce death and illness due to bacterial infectious diseases in the 21st century. 11Read moreRead less
Developing And Evaluating A Multimodal Antibiotic Allergy Strategy To Improve Antimicrobial Stewardship In High-risk Antibiotic Usage Populations

Summary
Antibiotic allergies lead to the use of inferior antibiotics and generation of “superbugs”. Antibiotic allergy testing removes up to 90% of allergies, although remains unavailable to many and unreliable in some severe antibiotic reactions. We aim to validate antibiotic allergy bedside tools and programs, and develop laboratory tests that can diagnose and prevent severe antibiotic allergies, to improve appropriate antibiotic prescribing and patient outcomes.
Modelling The Effects Of Immunity On Influenza Transmission - Implications For Prevention And Vaccine Development

Summary
There is uncertainty about how many people can be infected by a single person with influenza at the start of an outbreak. Some data suggest that a single generation of transmission can infect 10-20 other people. With such a rate of growth (ie 10-20 fold every 3 days) the spread of an influenza outbreak is virtually unstoppable. Other data suggest that each person with influenza infects less than 2 other people on average. With such a lower rate of growth, control would be more feasible. Our proj ....There is uncertainty about how many people can be infected by a single person with influenza at the start of an outbreak. Some data suggest that a single generation of transmission can infect 10-20 other people. With such a rate of growth (ie 10-20 fold every 3 days) the spread of an influenza outbreak is virtually unstoppable. Other data suggest that each person with influenza infects less than 2 other people on average. With such a lower rate of growth, control would be more feasible. Our project will use data from historic and contemporary outbreaks of influenza and build mathematical models to explain the rate of growth of an influenza outbreak in terms of: 1. The proportion of people exposed to influenza who do not become ill (although there can be evidence of infection if careful studies are made). This proportion is about 33%. 2. The proportion of people who are protected from influenza by immunity, whether induced by vaccination or by past exposure to natural influenza infection (this can vary from 0% in isolated populations which have not seen influenza for many years up to 80 or 90% in urbanised populations that are exposed to influenza almost every season). 3. Different rates of contact between different people and groups of people - some may be exposed so often that their immunity is boosted regularly without them becoming severely ill; others, living in more isolated circumstances, may be rarely exposed, but when they are, they are more likely to become severely ill. 4. The effects of influenza vaccine in inducing protective immunity - it is well known that there is good protection if the vaccine is well matched to the circulating virus. 5. The effects of live virus infection in inducing (short-lived) protection against a wider range of influenza viruses. Our model results will be used to guide vaccine design and pandemic planning.Read moreRead less

Summary
Engineering T cells to promote peripheral immunity. Tissue-resident memory T cells (TRM) are key for immune protection against infections and cancer. This has led to much interest in understanding how these immune cells develop, although elucidation of molecules that regulate TRM are still scarce. This project aims to (i) identify genetic drivers of TRM in peripheral organs and (ii) modulate TRM generation utilising state-of-the-art genetic engineering techniques.

This project aims to (i) identify genetic drivers of TRM in peripheral organs and (ii) modulate TRM generation utilising state-of-the-art genetic engineering techniques. Expected outcomes include generating new knowledge that will contribute to the development of novel therapeutics against infectious disease and cancer, together with the benefit of promoting national and international collaboration with the ultimate goal of improving health.Read moreRead less
Enhancing immunogenicity of DNA vaccines by targeted delivery to antigen presenting cells. Vaccines have proven to be one of the most effective means of preventing infection and also provide promise as a treatment for cancer. However, the range of effective technologies that make possible the delivery of vaccines that can protect against a broad range of infections is limited. DNA based vaccines are attractive because they are relatively easy to produce against a wide range of infections.

Vaccines have proven to be one of the most effective means of preventing infection and also provide promise as a treatment for cancer. However, the range of effective technologies that make possible the delivery of vaccines that can protect against a broad range of infections is limited. DNA based vaccines are attractive because they are relatively easy to produce against a wide range of infections. However, DNA vaccines often provide poor protection against infections. This project will explore a unique technology developed in Australia and that will greatly improve the effectiveness of DNA vaccines against a broad range of diseases. Read moreRead less
