The development and evaluation of a new therapy for the prevention and treatment of bacterial infections in hospitals. The technology used in this project will enable products to be developed from the Australian dairy industry which may safely provide protection and treatment for diarrhoea acquired in hospitals for which there are few effective options. The product will be cost effective and can be used as a public health tool to control outbreaks in those most susceptible to severe disease.
Molecular characterisation of hypervirulence and the infectious cycle in Clostridium difficile. Gut diseases caused by the bacterium Clostridium difficile are a significant animal and public health problem in Australia and many other countries. This project will allow us to understand how this bacterium causes disease, leading to the development of much needed preventative and treatment strategies for animals and human patients.
Host-pathogen interactions: the role of mimicry. The proposed research program, using a combination of structure and functional analysis will provide insight into the mechanism of nucleotide hydrolysis by the enzymes NTPDases. This study will not only improve our fundamental understanding of NTPDase action but could lead to the rational design of antimicrobials.

Summary
Subversion of innate immune responses by pathogenic Escherichia coli. This project will determine how bacteria that cause diarrhoeal diseases prevent the immune system from signalling efficiently. It will provide important information not only about how the bacteria establish disease, but also provide insight into the host response in the early stages of infection.
Designing effective Gram negative bacterial vaccines. There is a need for the development of novel vaccines for use in animals and humans. This project will to address this need by studying the functions of bacterial 'blebs' as potent inducers of the host immune system and by developing these nano-sized particles for use as safe and cost-effective vaccine candidates.
Identification of novel antigens for vaccination and immunotherapy against the human gastric pathogen, Helicobacter pylori. The bacterium Helicobacter pylori is a significant human pathogen which infects the stomach where it is the major cause of stomach and duodenal ulcers, plus two types of cancer. This project proposes to utilise a novel strategy to identify potential vaccine targets on the bacterial surface with the aim to develop an effective vaccine against this organism. Such a vaccine wo ....Identification of novel antigens for vaccination and immunotherapy against the human gastric pathogen, Helicobacter pylori. The bacterium Helicobacter pylori is a significant human pathogen which infects the stomach where it is the major cause of stomach and duodenal ulcers, plus two types of cancer. This project proposes to utilise a novel strategy to identify potential vaccine targets on the bacterial surface with the aim to develop an effective vaccine against this organism. Such a vaccine would protect against the development of stomach cancer, hence saving lives, plus significantly reduce the incidence of stomach ulcers, thereby reducing suffering of individuals and providing financial benefits to employers.Read moreRead less
The biology, structure and function of bacterial virulence effectors. This project is closely aligned with the National Research Priority of Promoting and Maintaining Good Health and will establish a research framework to investigate novel virulence processes that allow bacterial pathogens to infect humans and cause disease. This fresh approach to the study of bacterial pathogenesis will sit outside classic genetic methods to investigate infection and immunity which rely heavily on genetic manip ....The biology, structure and function of bacterial virulence effectors. This project is closely aligned with the National Research Priority of Promoting and Maintaining Good Health and will establish a research framework to investigate novel virulence processes that allow bacterial pathogens to infect humans and cause disease. This fresh approach to the study of bacterial pathogenesis will sit outside classic genetic methods to investigate infection and immunity which rely heavily on genetic manipulation of the pathogen. Other than providing fundamental information on host-pathogen interactions, this work may lead to novel disease interventions by inhibition of bacterial virulence factor activity and/or enhancement of host inflammatory and immune responses.Read moreRead less
Targeted isolation of specific marine bacterial species associated with higher organsims for the purpose of discovering new antimicrobial compounds. Specific bacterial species that are commonly found in association with marine plants and animals often produce active secondary metabolites. The aim of this project is to apply our understanding of these bacterial-host associations to the targeted isolation of novel antimicrobials from the marine environment. While these new compounds will undoubted ....Targeted isolation of specific marine bacterial species associated with higher organsims for the purpose of discovering new antimicrobial compounds. Specific bacterial species that are commonly found in association with marine plants and animals often produce active secondary metabolites. The aim of this project is to apply our understanding of these bacterial-host associations to the targeted isolation of novel antimicrobials from the marine environment. While these new compounds will undoubtedly have a number of commercial applications this project focuses on the development of products for dental hygiene in animals. Generally, the urgent need for new antimicrobial compounds to combat the growing number of microbes that are resistant to current antibiotics highlights the importance of this project.Read moreRead less
Understanding heat shock protein complex vaccines. This project aims to understand the mechanism of action and formulation requirements of a novel vaccine technology that utilises heat shock protein complexes. By understanding how this technology works, future vaccines can be improved to induce the immune response required to target specific pathogens, as well as give assurance regarding its safety.

Summary
An advanced flow cytometry facility for the Peter Doherty Institute. The establishment of a flow cytometry facility in the new Peter Doherty Institute for Infection and Immunity will enhance capacity to investigate immunity to a broad range of very serious diseases. This project will support researchers studying viral and bacterial infection as well as cancer and autoimmunity.
