Detection and viability of waterborne pathogens using a gut-on-chip. This project aims to resolve a significant problem for water utilities. Microbial pathogens Cryptosporidium, norovirus and adenovirus are the main public health concern for drinking water in developed nations. Water monitoring is limited by the lack of fast, reliable detection methods and viability assays for these pathogens. This project will use a novel gut-on-a-chip to develop for the first time rapid infectivity assays for ....Detection and viability of waterborne pathogens using a gut-on-chip.

Water monitoring is limited by the lack of fast, reliable detection methods and viability assays for these pathogens. This project will use a novel gut-on-a-chip to develop for the first time rapid infectivity assays for Cryptosporidium, norovirus and adenovirus. Significant benefits include improved diagnostics and water disinfection assays, improved water treatment and reduced costs with global impact.Read moreRead less
Transport and innate immune properties of DNA in bacterial nano-sized vesicles. All types of living organisms release nano-sized membrane vesicles or “blebs” which they use for intercellular communication and transport of molecules. This project will determine how bacteria package DNA within these vesicles, how this DNA is transported into host cells and how it triggers immune responses in these cells.
Ecology and transmission of tick-borne disease in Australia. Ecology and transmission of tick-borne disease in Australia. This project aims to determine the bacterial, protozoal and viral biodiversity in wildlife ticks and their native mammal hosts, and provide new information about the biology and transmission dynamics of these microorganisms and their potential to cause disease in wildlife, domesticated animals and humans. Anticipated outcomes are improved diagnostic tests and management proto ....Ecology and transmission of tick-borne disease in Australia. Ecology and transmission of tick-borne disease in Australia.

Development of small molecule primary sulfonamides as new drugs for malaria. Malaria is a major global health threat, causing approximately 800,000 deaths annually. Lives can be saved if patients are treated. The use of current antimalarial drugs is limited by drug resistance, low activity and poor safety. This project investigates the effectiveness of a new class of molecule as a safe drug treatment option to kill malaria parasites.
Mechanisms of subversion of malarial immunity. This project will aim to understand how the Malaria parasite, which causes one of the world’s deadliest diseases, evades immunity. It will provide novel understanding of immunity against malaria and impact on current strategies to develop an efficacious vaccine or treatment for malaria.
How bacteria cause disease in the urinary tract. This project will investigate the virulence properties of uropathogenic Escherichia coli, the major causative agent of urinary tract infections (UTI) in humans. The results will help to understand how these bacterial pathogens cause disease and will impact strategies aimed at the prevention and treatment of chronic and recurrent UTI.
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

Summary
Exploiting pathogen-host interactions to dissect the mammalian endocytic pathway. Salmonella manipulates the cells of the human body to cause disease. Understanding the molecular machinery that controls this process will provide profound insight into how the bacteria orchestrates this manipulation as well as provide possible avenues for intervention and even cures for diseases like typhoid fever.
Bio-engineering Insect-Specific Flaviviruses for control of arboviruses. This project aims to study a family of commensal viruses of mosquitoes called insect-specific flaviviruses that are naturally found in mosquitoes and do not infect or cause disease in vertebrate hosts. Using an innovative approach, this project employs cutting-edge molecular virology approaches to modify these insect-specific flaviviruses to enhance their ability to block the replication of other pathogenic viruses in the m ....Bio-engineering Insect-Specific Flaviviruses for control of arboviruses. This project aims to study a family of commensal viruses of mosquitoes called insect-specific flaviviruses that are naturally found in mosquitoes and do not infect or cause disease in vertebrate hosts. Using an innovative approach, this project employs cutting-edge molecular virology approaches to modify these insect-specific flaviviruses to enhance their ability to block the replication of other pathogenic viruses in the mosquito vector. Expected outcome of this project is a bio-control strategy that is complementary to the Wolbachia approach. The anticipated benefits include the advancement of knowledge of insect-specific flaviviruses, and promotion of interdisciplinary research across the fields of Entomology and Virology.Read moreRead less
Emergence of a virulent strain of West Nile virus causing fatal equine encephalitis in south-eastern Australia. In 2011 a large outbreak of encephalitis in horses occurred in south-eastern Australia that was caused by a new virus that is transmitted by mosquitoes and is related to West Nile virus, known to cause severe disease in humans and horses. This project will study this new virus and develop improved methods for diagnosis and control of this disease.
