Harnessing the genome of the Australian paralysis tick to develop effective control products. This project aims to examine the potent cocktail produced by the salivary gland of Australia's paralysis tick. The paralysis tick continues to cause severe illness and deaths for companion pets with up to 100,000 cases of toxicoses per year. This project aims to develop new safe treatments and/or preventative vaccines.
Phase-variable epigenetic regulators in bacterial veterinary pathogens. This project aims to identify phasevarion regulated genes in the major bacterial swine pathogens Streptococcus suis and Actinobacillus pleuropneumoniae. Both species contain randomly switching epigenetic regulators that control expression of multiple genes by epigenetic mechanisms. Identifying phasevarion controlled genes will inform and direct future vaccine development for important livestock species.
Development of a live vaccine for gut health in poultry. Development of a live vaccine for gut health in poultry. The project aims to develop a live vaccine against necrotic enteritis, a disease of poultry estimated to cost the global poultry industry $5-6 billion USD/annum. It builds on work that has demonstrated the efficacy of an experimental vaccine. The proven antigen, NetB, will be expressed in live delivery vehicles, including the apicomplexan parasite Eimeria and several bacteria strains ....Development of a live vaccine for gut health in poultry. Development of a live vaccine for gut health in poultry. The project aims to develop a live vaccine against necrotic enteritis, a disease of poultry estimated to cost the global poultry industry $5-6 billion USD/annum. It builds on work that has demonstrated the efficacy of an experimental vaccine. The proven antigen, NetB, will be expressed in live delivery vehicles, including the apicomplexan parasite Eimeria and several bacteria strains particularly suited to use in chickens. Comparative analysis of the different vaccine vehicles will allow evaluation of the relative advantages and disadvantage of the different vehicles for delivery of heterologous vaccine antigens, thus informing the choice of appropriate vectors for this and other vaccine applications.Read moreRead less
Improving clostridial toxoid production through molecular fermentation maps. This project aims to improve vaccine production by generating detailed molecular maps of fermentation which will be used to design superior fermentation processes with reduced cost. Toxoid vaccines, used routinely in the livestock industry to prevent animal-disease caused by pathogenic Clostridia, are produced using batch fermentation processes. These processes have undergone limited optimisation over the past five deca ....Improving clostridial toxoid production through molecular fermentation maps. This project aims to improve vaccine production by generating detailed molecular maps of fermentation which will be used to design superior fermentation processes with reduced cost. Toxoid vaccines, used routinely in the livestock industry to prevent animal-disease caused by pathogenic Clostridia, are produced using batch fermentation processes. These processes have undergone limited optimisation over the past five decades. Low titres and frequent batch failures greatly affect capital use and represent a significant cost. In addition, current optimisation approaches are limited by the use of expensive and noisy endpoint assays. This project aims to use high-throughput chemistry (multi-omics) that overcome these limitations.Read moreRead less
Engineering a nanovaccine for cost-effective influenza poultry vaccination. The project aims to develop a new single-dose, room temperature-stable nanovaccine for cost-effective influenza poultry vaccination. The nanovaccine is based on viral protein assembly modularised to present multiple copies of influenza antigen. Particularly, this project focuses on the engineering of this vaccine manufacturing and formulation for a room temperature-stable vaccine.

The project aims to develop a new single-dose, room temperature-stable nanovaccine for cost-effective influenza poultry vaccination. The nanovaccine is based on viral protein assembly modularised to present multiple copies of influenza antigen. Particularly, this project focuses on the engineering of this vaccine manufacturing and formulation for a room temperature-stable vaccine. The resulting engineered vaccine would play an important role in preventing avian influenza outbreaks, which are currently affecting both developed and developing countries, costing millions of dollars due to the death and culling of infected poultry.Read moreRead less

The applicant has discovered a new pathway for protein production in bacteria. The primary objective of this project is to use a diverse array of biochemical and biophysical techniques to understand how this new protein production platform works. We will also assess this new pathway for the production of proteins of interest to the biotechnology sector. This project expects to determine how this system can be exploited for use in the growing Australian bioeconomy.Read moreRead less

Development of a vaccine to protect koalas against koala retrovirus (KoRV). This project aims to develop a vaccine against koala retrovirus (KoRV) to arrest the increasing loss of animals due to this infection. Along with Chlamydia, KoRV threatens the long-term survival of the koala. KoRV infects over 95 per cent of Australia’s koalas and has been strongly linked to lymphoma and leukemia. Although quarantine and antiretroviral drug treatment are possible control measures, they are impractical in ....Development of a vaccine to protect koalas against koala retrovirus (KoRV). This project aims to develop a vaccine against koala retrovirus (KoRV) to arrest the increasing loss of animals due to this infection. Along with Chlamydia, KoRV threatens the long-term survival of the koala. KoRV infects over 95 per cent of Australia’s koalas and has been strongly linked to lymphoma and leukemia. Although quarantine and antiretroviral drug treatment are possible control measures, they are impractical in the wild, leaving vaccination as the only realistic option. This is valuable for both wild and captive koalas; zoos report high animal losses due to KoRV-associated lymphoma. The main outcome will be a KoRV vaccine which can be combined with a Chlamydia vaccine which is being developed in parallel.Read moreRead less

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

Understanding equine incretins: a novel approach to laminitis prevention. Laminitis is a crippling foot disease in horses which incurs significant economic and social costs. Recent studies have shown that persistently high insulin concentrations can trigger laminitis, and that high insulin levels are caused by the excessive release of hormones called incretins. This project aims to determine the role of incretins and their receptors in causing abnormal equine insulin secretion.

Recent studies have shown that persistently high insulin concentrations can trigger laminitis, and that high insulin levels are caused by the excessive release of hormones called incretins. This project aims to determine the role of incretins and their receptors in causing abnormal equine insulin secretion. The distribution of equine incretin receptors will be described for the first time, and the consequences of incretin receptor binding will be characterised. Understanding equine incretin biology may lead to novel therapies for laminitis.Read moreRead less
