The aim of the project is to develop a vaccine to reduce Campylobacter bacteria in chickens. Campylobacters cause disease in both poultry and humans. Poultry products are the most common source of human infections. By reducing Campylobacter in poultry, the transfer to humans will be reduced. The expected outcomes arising from this work will be a reduction of the economic burden of poultry losses, in an Australian industry valued at $2.8 billion/year, and an improvement in food safety, thus helping to reduce the burden of foodborne illness, estimated to be $1.2 billion dollars/year. This project is, therefore, poised to benefit the Australian economy, specifically primary producers and the general public, by targeted vaccination of poultry.Read moreRead less

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

Summary
Improving poultry health and performance through microbiota manipulations. The project aims to develop methods to modulate microbiota to improve poultry health and productivity and reduce the need for antibiotics. Probiotic administration is currently the only way in agriculture to restore imbalanced intestinal microbiota. Recent research shows that intestinal microbiota resist all new-coming bacteria and remove them from the intestinal environment. The initial inoculum at the time of birth shap ....Improving poultry health and performance through microbiota manipulations. The project aims to develop methods to modulate microbiota to improve poultry health and productivity and reduce the need for antibiotics. Probiotic administration is currently the only way in agriculture to restore imbalanced intestinal microbiota. Recent research shows that intestinal microbiota resist all new-coming bacteria and remove them from the intestinal environment. The initial inoculum at the time of birth shapes the gut microbiota for life and has the strongest influence on development of the immune system. Accordingly, at-hatch administration of proven beneficial strains to poultry is likely to ensure permanent colonisation with beneficial bacteria. This process would improve both the productivity and health of poultry and other agricultural animals.Read moreRead less

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

New vaccines and diagnostics to control viral disease in farmed crocodiles. Infection of farmed crocodiles with West Nile virus (WNV) causes lesions in the skin that render the hides unsuitable for high quality leather products. This results in >$20 million lost revenue to the Australian crocodile industry annually. We have developed a novel technology to generate safe and effective vaccines and diagnostic tests for WNV in animals.

Infection of farmed crocodiles with West Nile virus (WNV) causes lesions in the skin that render the hides unsuitable for high quality leather products. This results in >$20 million lost revenue to the Australian crocodile industry annually. We have developed a novel technology to generate safe and effective vaccines and diagnostic tests for WNV in animals. We aim to 1) conduct vaccine trials in farmed crocodiles to determine the optimum dose formulation and immunisation regime to provide long-lived protection against WNV disease; 2) validate pen-side tests to rapidly diagnose WNV infection in crocodiles on farms; and 3) transfer the technology to a manufacturing facility to ensure a commercial supply of the vaccines and diagnostic tests.

This project aims to develop a new nano-pesticide with improved safety and performance. Ticks and buffalo fly cause over $400 million each year in economic losses to the Australian livestock industry and are currently treated with highly toxic synthetic pesticides. Spinosad, a naturally derived pesticide with low environmental impact and low toxicity, will be loaded into silica hollow spheres which will improve adhesion to skin or hair and protect against ultraviolet degradation. The nano-spinosad pesticide is expected to have enhanced efficacy and effective duration in field conditions compared to conventional pesticides, significantly reducing the cost of pest control.Read moreRead less
Assessing animal exposure to urticating caterpillar hairs and developing management strategies to reduce the consequence of foetal abortion in mares. Equine Amnionitis and Foetal Loss (EAFL) accounts for about a third of mares aborting in thoroughbred horse studs in southern Queensland, New South Wales and Victoria. Previous studies have shown that processionary caterpillars and their irritating setae (hairs) can cause EAFL. This project aims to determine the likelihood that other caterpillar sp ....Assessing animal exposure to urticating caterpillar hairs and developing management strategies to reduce the consequence of foetal abortion in mares. Equine Amnionitis and Foetal Loss (EAFL) accounts for about a third of mares aborting in thoroughbred horse studs in southern Queensland, New South Wales and Victoria. Previous studies have shown that processionary caterpillars and their irritating setae (hairs) can cause EAFL. This project aims to determine the likelihood that other caterpillar species are involved based on hair morphology and a surrogate model system. A full risk assessment of the exposure of mares to these hairs in situ will be undertaken, based on the ecology and biology of the species. Outcomes include a management strategy for EAFL-causing insects and a reduction of EAFL within the industry.Read moreRead less
