Summary
This project will study how the bacteria that cause infant diarrhoea colonize the intestine and induce disease. We have identified a novel genetic region that allows E. coli to survive and persist in the intestine. Similar genes are also present in closely related organisms. This project will help us to undestand how new diseases evolve and emerge and may lead to the development of new vaccines to protect against infant diarrhoea.
Pathogenomics: New Ways To Exploit Genome Sequence Data From Pathogenic Bacteria.

Summary
Bacterial pathogens are locked in an evolutionary battle of survival with their eukaryote hosts. The rapidly evolving genes of medically-important pathogens are generally those required for adaptation to the human host. This project aims to exploit the abundance of available bacterial genome sequences to predict rapid evolution in bacterial pathogens using computational methods. The protein products of such genes offer novel targets for therapeutic intervention.
Bacterial Pathogenomics: Whole-genome Sequencing To Investigate Infection Transmission, Pathogenesis And Antibiotic Resistance

Summary
As bacterial superbugs – resistant to multiple antibiotics – dominate the headlines, the pipeline for new antibiotics has all but dried up. High-throughput DNA sequencing heralds a golden opportunity for infectious disease research. By studying the entire collection of genes - the genome - of large numbers of multidrug resistant bacterial strains, we aim to better understand the genetic changes that govern the emergence and global spread of superbugs and translate these findings into the clinic.
Infectious pathogens invade cells by hijacking cellular pathways, termed endocytosis, that normally internalise material from outside the cell. We will identify the molecular details of these pathways and how they are modulated in response to infection with Salmonella, a leading cause of human gastroenteritis. Such studies are necessary in order to understand host-pathogen interactions so that treatments can be developed targeting the symptoms of infection
This program will investigate the strategies used by pathogenic bacteria to cause human diseases. The research will focus on how bacteria initiate infections, how they invade, cause cell and tissue damage and respond to their human host. It will also examine how the host’s innate immune system interacts with these bacteria. The results will provide new insights into host-pathogen interactions and reveal new targets for the development of novel antibacterial drugs and vaccines.
Modulation of air-conditioning settings to destroy respiratory viruses. This project aims to prove that manipulating the ambient humidity can rapidly degrade airborne viruses. The relationship between ambient humidity and airborne infection is poorly understood for viral pathogens including influenza and the common cold. The project will prove that indoor environmental conditions can be easily manipulated to kill airborne viruses. The findings will be used to develop indoor air humidity control ....Modulation of air-conditioning settings to destroy respiratory viruses. This project aims to prove that manipulating the ambient humidity can rapidly degrade airborne viruses. The relationship between ambient humidity and airborne infection is poorly understood for viral pathogens including influenza and the common cold. The project will prove that indoor environmental conditions can be easily manipulated to kill airborne viruses. The findings will be used to develop indoor air humidity control guidelines targeting the vulnerabilities of the viruses to minimise airborne infection.Read moreRead less
Role Of HtrA And RseP, Stress Response Proteases, In Development And Persistence Of Chlamydia Trachomatis Infections

Funding Amount

Summary
This project will research the most commonly reported bacterial sexually transmitted infection Chlamydia trachomatis. Bacterial proteins which could play a role in chronic infections of humans will be investigated. Proteins will be biologically examined to determine their role during disease. This may identify proteins which could be used for diagnostic and therapeutic tools to prevent chronic Chlamydia infection (which can result in infertility and other serious conditions).
Squamous cell carcinoma of the skin is extremely common in Australia, resulting in disfiguring surgeries and deaths. Although cumulative sun exposure is important, some people are very susceptible, and we do not know why. This project hinges on the notion that skin cancer is a complex (many genes involved). We will utilize novel systems to harness this complexity to understand why some people are resistant and others very susceptible so as to design appropriate control measures and treatments.
