Summary
We have established a mouse model that has been genetically modified and cannot produce the cytokine tumour necrosis factor. This cytokine is secreted in the beginning of the inflammatory response. If these mice are infected with a parasite they are not able to heal the infection and die quickly. We can demonstrate that these mice cannot regulate the beginning inflammatory response and do not form a cellular infiltrate at the site of infection.

Summary
PNG has the highest infant and childhood mortality in the Pacific with malaria accounting for 15% of infant mortality. Diagnosing and investigating malaria in this setting is hard because the symptoms are similar to other diseases. We aim to accurately describe clinical and laboratory features and risk factors for malaria, severe non malarial disease and mortality. We are investigating an outbreak of unexplained encephalitis as well.
Urinary tract infections (UTI) are among the most common infectious diseases of humans and a major cause of morbidity and mortality. In the USA, UTI accounts for >$1.6 billion in medical expenses each year. It is estimated that 50% of women will develop a UTI in their lifetime. This research aims to understand the processes by which bacteria colonize the human bladder. The work has implications for the development of new approaches to prevent and treat UTI.

Summary
Penicillium marneffei is a fungus that causes disease in patients with depressed immunity. This project models this infection in zebrafish, which have advantages for modelling infectious disease. It uses fluorescent fungi and fish with fluorescent immune cells to study the way white blood cells fight this infection, and mutant zebrafish and mutant fungi to find new therapeutic targets in the host-pathogen interaction.

Summary
Mycobacterial infections remain a major burden of modern society. This proposal aims to define the role of an understudied immune cell subset, gamma-delta T cells, in the response against mycobacteria. We will use cutting-edge multi-photon imaging to track these cells in real-time directly within infected tissues. This will facilitate generating a new vista of anti-mycobacterial immune responses and may aid the development of improved vaccines.

An influenza pandemic causing by highly pathogenic H5N1 virus may occur in the near future. As a vaccine for H5N1 will not be available in the foreseeable months, antiviral drugs are the only possible choice for prophylaxis and treatment. Currently only two drugs have been clinically proven to be effective against H5N1 strain and the emergence of drug resistant in H5N1 influenza virus has been reported which may significantly hamper the treatment. Understanding and monitoring the emergence of th ....An influenza pandemic causing by highly pathogenic H5N1 virus may occur in the near future. As a vaccine for H5N1 will not be available in the foreseeable months, antiviral drugs are the only possible choice for prophylaxis and treatment. Currently only two drugs have been clinically proven to be effective against H5N1 strain and the emergence of drug resistant in H5N1 influenza virus has been reported which may significantly hamper the treatment. Understanding and monitoring the emergence of these drug resistant strains during local spreading will be critical in managing an H5N1 influenza pandemic in Australia. In the proposed project, we will develop important diagnostic tools using our world leading Rolling Circle Amplification (RCA) technology for the monitoring of the development and possible transmission of drug resistant influenza strains. Upon finishing the project, at lease three sensitive diagnostic methods will be developed for the detection of the emergence of drug resistance at the very early stage.Read moreRead less

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.

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
This Centre of Research Excellence will translate the best available evidence to improve cancer outcomes through better management of infections in cancer patients, a rapidly growing group. We will establish new research networks to detect emerging multi resistant infections, develop guidelines on how to manage them, implement locally successful programs that have been shown to save lives nationally and validate new practice changing immune, bioinformatics and diagnostic technologies.
