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

Summary
Bacterial cell invasion factors as vaccine targets. This project aims to determine the virulence factors responsible for cellular invasion and systemic spread of Mycoplasma bovis, and use genome editing technologies (CRISPR-Cas9) to create gene knock out mutants that cannot invade host cells and test their potential as vaccine candidates in animals. Mycoplasma bovis is an emerging cause of mastitis, the most important infectious disease in the dairy industry, and causes significant economic loss ....Bacterial cell invasion factors as vaccine targets. This project aims to determine the virulence factors responsible for cellular invasion and systemic spread of Mycoplasma bovis, and use genome editing technologies (CRISPR-Cas9) to create gene knock out mutants that cannot invade host cells and test their potential as vaccine candidates in animals. Mycoplasma bovis is an emerging cause of mastitis, the most important infectious disease in the dairy industry, and causes significant economic losses. The vaccine candidates developed in this project are expected to be used to control outbreaks of mastitis, and to improve biosecurity, production and animal welfare in the Australian and global dairy industries.Read moreRead less
Role of Pasteurella surface polysaccharides in pathogenesis and immunity. Livestock infections cause major economic losses worldwide. The bacterium Pasteurella multocida causes multiple diseases in a range of livestock, including hemorrhagic septicaemia in cattle and fowl cholera in poultry. Two surface polysaccharide structures, capsule and lipopolysaccharide, are crucial for P. multocida to cause disease. Our data indicate that varying the amount/content of these structures also affects vaccin ....Role of Pasteurella surface polysaccharides in pathogenesis and immunity. Livestock infections cause major economic losses worldwide. The bacterium Pasteurella multocida causes multiple diseases in a range of livestock, including hemorrhagic septicaemia in cattle and fowl cholera in poultry. Two surface polysaccharide structures, capsule and lipopolysaccharide, are crucial for P. multocida to cause disease. Our data indicate that varying the amount/content of these structures also affects vaccine performance. This project aims to identify how the production of these P. multocida structures are controlled and if changes to these structures affect its ability to infect different animals/birds. Using this information, the project aims to develop state-of-the-art livestock vaccines with superior disease coverage.Read moreRead less
Targeted drug discovery against blood-feeding parasite nematodes of animals. This project aims to identify more sustainable control strategies of nematode parasites of livestock, which cost more than 400 million yearly to the Australian wool and meat industry. The project expects to identify novel nematicides and generate knowledge of the parasite biology using a combination of high-throughput drug discovery screens with cutting-edge OMICs approaches to target a key molecular pathway of importan ....Targeted drug discovery against blood-feeding parasite nematodes of animals. This project aims to identify more sustainable control strategies of nematode parasites of livestock, which cost more than 400 million yearly to the Australian wool and meat industry. The project expects to identify novel nematicides and generate knowledge of the parasite biology using a combination of high-throughput drug discovery screens with cutting-edge OMICs approaches to target a key molecular pathway of importance to the survival of nematodes, namely their blood-feeding behaviour. Expected outcomes of this project include a likely enhancement of international efforts in controlling these parasites as well as nematicides commercialisation. This should provide significant benefits to agricultural producers in Australia and worldwide.

Imperfect vaccination drives herpesvirus evolution through recombination. Vaccines are used to help control disease caused by herpesviruses in animals, but some vaccination programs may drive the evolution and spread of herpesviruses with increased fitness (transmissibility, replication and virulence) through recombination. This project aims to study an important avian herpesvirus (infectious laryngotracheitis virus) in the natural host (poultry) to gain fundamental knowledge of how vaccination ....Imperfect vaccination drives herpesvirus evolution through recombination. Vaccines are used to help control disease caused by herpesviruses in animals, but some vaccination programs may drive the evolution and spread of herpesviruses with increased fitness (transmissibility, replication and virulence) through recombination. This project aims to study an important avian herpesvirus (infectious laryngotracheitis virus) in the natural host (poultry) to gain fundamental knowledge of how vaccination programs influence the emergence of diverse recombinant viruses, and identify which types of vaccination programs are best at preventing the emergence of fitter and more virulent viruses. The results are expected to inform vaccination practices to allow more effective control of these viruses in poultry and other animals.Read moreRead less
New vaccines and diagnostics to control viral disease in farmed crocodiles.

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.

Mechanisms of immune protection for infectious laryngotracheitis virus. This project aims to investigate the mechanisms of immune protection against infectious laryngotracheitis virus. This will be achieved by investigating the role of local and systemic immunity and the immune cells associated with long-term protection against disease. The mechanisms of protection against this virus remain unknown which impairs the development of efficacious vaccines.

This project aims to investigate the mechanisms of immune protection against infectious laryngotracheitis virus. This will be achieved by investigating the role of local and systemic immunity and the immune cells associated with long-term protection against disease. The mechanisms of protection against this virus remain unknown which impairs the development of efficacious vaccines. Expected outcomes of this project are a more rational approach to vaccination resulting in the generation of more effective and safer vaccination strategies that should benefit our important poultry industry. Additionally, the new methodologies and knowledge on mucosal immune markers could be utilised for the study of other pathogens.Read moreRead less

The overall aim of this project is to improve global honeybee health by developing novel bee-friendly bioinsecticides as well as treatments against honeybee parasites such as varroa mites and small hive beetles. This project seeks to significantly improve existing insecticidal lead peptides from spider venoms to increase their oral toxicity and make them more pest-specific. Expected outcomes of this project include a panel of biologically degradable venom peptides that are active against selected pest and parasite species and that can be economically produced in large scale. This would not only provide significant environmental, social and economical benefits on a global scale, but also boost the Australian agrochemical research sector.Read moreRead less
