Do insect-specific flaviviruses regulate the transmission of mosquito-borne diseases in Australia? Mosquito-borne viral diseases such as dengue occur in Australia. The research team recently discovered related viruses in mosquitoes from Darwin that do not infect humans, but may inhibit the spread of viral diseases by mosquitoes. This project will investigate the life cycles of these new viruses to understand how they affect the spread of viral diseases by mosquitoes.

Summary
Development of next generation drugs against Helicobacter pylori. Gastric cancer is the second leading cause of cancer-related death in the world and infection by Helicobacter pylori bacteria is the main cause of this disease. The aim of this project is to develop new approaches to treat Helicobacter pylori infection that will give superior results and lower side effects than available therapies.
Herpesvirus entry into mammalian hosts. Herpesviruses infect most mammals and cause much chronic disease. Our poor understanding of their host entry pathways limits infection control. The olfactory neuroepithelium has been identified as a key entry portal for both a murid herpesvirus and a human pathogen, Herpes simplex virus, suggesting that many herpesviruses use this route. Virions cross the olfactory mucus on neuronal cilia, then either infect neurons or transfer to glial cells for local spr ....Herpesvirus entry into mammalian hosts. Herpesviruses infect most mammals and cause much chronic disease. Our poor understanding of their host entry pathways limits infection control. The olfactory neuroepithelium has been identified as a key entry portal for both a murid herpesvirus and a human pathogen, Herpes simplex virus, suggesting that many herpesviruses use this route. Virions cross the olfactory mucus on neuronal cilia, then either infect neurons or transfer to glial cells for local spread. This project will identify key receptor interactions and map the extent of invasion. By advancing our basic understanding of these important viruses and their uptake at an abundantly exposed but little explored anatomical site, the project can establish a basis for vaccinating against chronic disease.Read moreRead less
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.

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

Summary
Transmission dynamics modelling of zoonotic neglected tropical diseases. This project will develop mathematical models to simulate zoonotic disease transmission and control. Results will provide novel insight for policy makers into effective interventions for schistosomiasis, echinococcosis and clonorchiasis, as well as provide a methodological platform for adaptation to other zoonotic emerging and re-emerging diseases.

Chlamydial infections of birds, domesticated animals and humans. This project aims to investigate the epidemiology of an avian Chlamydia pathogen that is known to infect humans and animals, causing serious disease. Utilising molecular epidemiology approaches, this project will generate new knowledge about dynamics of where, when and how this infection spill-over occurs between different hosts.

This project aims to investigate the epidemiology of an avian Chlamydia pathogen that is known to infect humans and animals, causing serious disease. Utilising molecular epidemiology approaches, this project will generate new knowledge about dynamics of where, when and how this infection spill-over occurs between different hosts. This project also aims to extend early development work on an innovative diagnostic system for detection of chlamydia in laboratory and point-of-care scenarios. The expected outcomes are a greatly enhanced understanding of infections in humans and animals caused by this understudied pathogen, which will allow for more effective control and management of these infections.Read moreRead less

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.
Next generation dengue diagnostics. The 2009 dengue epidemic was widespread and the largest in North Queensland for 50 years. The outbreak was not quickly contained despite an extensive education program and a mosquito control taskforce. All four types of Dengue were detected, greatly increasing the chance of more severe complications such as Dengue haemorrhagic fever and Dengue shock syndrome. This project will improve our knowledge of Dengue proteins used in tests to diagnose the virus. The ne ....Next generation dengue diagnostics. The 2009 dengue epidemic was widespread and the largest in North Queensland for 50 years. The outbreak was not quickly contained despite an extensive education program and a mosquito control taskforce. All four types of Dengue were detected, greatly increasing the chance of more severe complications such as Dengue haemorrhagic fever and Dengue shock syndrome. This project will improve our knowledge of Dengue proteins used in tests to diagnose the virus. The new knowledge will be used to develop an easy to use test to diagnose Dengue infection early, rapidly and accurately. Effective diagnosis of Dengue will then allow timely implementation of intervention strategies (mosquito control, public advice, isolation and care).Read moreRead less
