Discovery of Novel Respiratory Viruses Causing Influenza-Like Illness in Healthy Australian Adults Aged 18 to 64 Years. This work will inform our understanding of the causes of acute respiratory illnesses in Australia at the present time by looking for both known and previously undiscovered respiratory viruses. Increasing the knowledge base regarding causes of disease will have downstream relevance for health policy planners seeking to assess the burden of disease due to different causes.

This work will inform our understanding of the causes of acute respiratory illnesses in Australia at the present time by looking for both known and previously undiscovered respiratory viruses. Increasing the knowledge base regarding causes of disease will have downstream relevance for health policy planners seeking to assess the burden of disease due to different causes. Early identification and description of new diseases will allow pre-emptive evaluation of new public health threats. This information will help to ensure availability and marketability of vaccines to prevent infection.Read moreRead less
Antiviral compounds to inhibit the replicase of hepatitis C virus. Hepatitis C virus is a major public health problem. There are currently 200,000 infected individuals in Australia and 16,000 new infections every year. There is no specific treatment and current therapy treats a small percentage of patients only, which consists of interferon-alpha and ribavirin. This results in side effects and only a 50% cure rate. This study's outcomes are expected to lead to greater access to treatment and imp ....Antiviral compounds to inhibit the replicase of hepatitis C virus. Hepatitis C virus is a major public health problem. There are currently 200,000 infected individuals in Australia and 16,000 new infections every year. There is no specific treatment and current therapy treats a small percentage of patients only, which consists of interferon-alpha and ribavirin. This results in side effects and only a 50% cure rate. This study's outcomes are expected to lead to greater access to treatment and improved therapy resulting in higher cure rates and in a dramatic reduction in the cost of treating patients. A novel therapy will provide considerable benefits for the national biotechnology industry.Read moreRead less
Exploring the role of the domestic dog and wild rodents as peri-domestic reservoirs of Rickettsia felis. This project aims to explore the role of domestic dogs and wild rats as maintenance hosts for flea-borne spotted fever. Cases of this disease, transmitted to humans by the common dog and cat flea are being increasingly recognised throughout the world. The findings of this study will add significant importance to flea control in pets.
The first integrated multimodal assay for the ultrasensitive detection of dengue contamination of blood. This project will develop the first screening test to check for dengue contamination of blood donations in Australia. This will help ensure safe, continued supply from blood donors, particularly in Queensland where dengue is on the rise.
Biocontrol of foaming in activated sludge plants with bacteriophages. Activated sludge systems are the most widely used processes for treating wastewater in Australia. Yet most eventually suffer from episodes of bulking and foaming, where high levels of biosolids leave the plant with the treated waste, representing serious pollution hazards. Attempts to solve these problems have met with limited success.The highly novel biocontrol method proposed here will provide a specific, environmentally fri ....Biocontrol of foaming in activated sludge plants with bacteriophages.

Equine infectious respiratory disease after long distance confined transportation. This project aims to identify the viruses and bacteria that are shed from the respiratory tract of horses after long distance confined transportation (eg, in horse floats and aeroplane stalls). Horses are transported long distances with increasing frequency, but the risk of serious respiratory disease to these horses, and the subsequent risk to other horses at the destination has not been investigated. This projec ....Equine infectious respiratory disease after long distance confined transportation. This project aims to identify the viruses and bacteria that are shed from the respiratory tract of horses after long distance confined transportation (eg, in horse floats and aeroplane stalls). Horses are transported long distances with increasing frequency, but the risk of serious respiratory disease to these horses, and the subsequent risk to other horses at the destination has not been investigated. This project will develop novel, non-invasive diagnostic techniques to facilitate early detection of these micro-organisms and will utilise new molecular genetic methods to identify the virulent strains of these organisms and to increase our understanding of their epidemiology.

Development and Assessment of Chimaeric Feline Caliciviruses as Vaccines. Feline caliciviruses are major pathogens of cats worldwide, but current vaccines offer only incomplete protection. This project aims to develop novel recombinant vaccine strains that will generate more cross protective immunity and thus provide greater protection for vaccinated cats.
Salmonella in poultry: improving vaccine efficacy . The central aim of this project is to increase the antigenicity of aroA mutant Salmonella Typhimurium vaccines, in particular Bioproperties’ Vaxsafe® ST. Increased antigenicity will affect the gut microbiota and stimulate a stronger host immune response improving vaccine efficacy and the duration of protection against S. Typhimurium in poultry. This will ultimately reduce bacterial loads in the farm environment, mitigate downstream contaminatio ....Salmonella in poultry: improving vaccine efficacy . The central aim of this project is to increase the antigenicity of aroA mutant Salmonella Typhimurium vaccines, in particular Bioproperties’ Vaxsafe® ST. Increased antigenicity will affect the gut microbiota and stimulate a stronger host immune response improving vaccine efficacy and the duration of protection against S. Typhimurium in poultry. This will ultimately reduce bacterial loads in the farm environment, mitigate downstream contamination of the food supply chain, and reduce the number of human salmonellosis cases.Read moreRead less
Reduction of antibiotic usage in the commercial pig industry. This project intends to identify factors that make a pig enterprise more likely to use high levels of antibiotics and develop alternative, vaccination-based methods for disease control. The development of multi-drug resistance in zoonotic bacterial pathogens (e.g. Salmonella and Campylobacter spp.) in pigs has raised concerns that antimicrobial resistance can be transferred from livestock to humans. Although the epidemiology to suppor ....Reduction of antibiotic usage in the commercial pig industry. This project intends to identify factors that make a pig enterprise more likely to use high levels of antibiotics and develop alternative, vaccination-based methods for disease control. The development of multi-drug resistance in zoonotic bacterial pathogens (e.g. Salmonella and Campylobacter spp.) in pigs has raised concerns that antimicrobial resistance can be transferred from livestock to humans. Although the epidemiology to support a claim that there is a causal association between antimicrobial use in food animals and public health is complex there is universal agreement that use of antimicrobials in food animal production should be minimised. This project intends to deliver outcomes that will reduce antibiotic use on commercial pig farms.Read moreRead less
Development of an Attenuated Infectious Laryngotracheitis Virus Vaccine. This project will develop novel methods for identification of genes involved in virulence of the important avian pathogen Infectious Laryngotracheitis Virus and produce an attenuated, antigenically marked infectious laryngotracheitis virus vaccine strain by specific disruption and deletion of two or more genes in the virusÕs genome.

Infectious laryngotracheitis is a major disease of chickens throughout the world, but current vaccines retain some capacity to cause disease. The development of novel attenuated vaccines will thus enhance control of this important disease of poultry.Read moreRead less
