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

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.

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
How do kangaroo herpesviruses jump to new host species? . This project aims to study alphaherpesviruses of kangaroos and other marsupials. These viruses cause outbreaks of severe disease in captive populations of marsupials when they are transmitted from natural hosts to new host species, but these cross-species transmission events are poorly understood. This project aims to study these viruses, and their capacity for cross-species transmission, using new approaches that consider herpesviruses a ....How do kangaroo herpesviruses jump to new host species? . This project aims to study alphaherpesviruses of kangaroos and other marsupials. These viruses cause outbreaks of severe disease in captive populations of marsupials when they are transmitted from natural hosts to new host species, but these cross-species transmission events are poorly understood. This project aims to study these viruses, and their capacity for cross-species transmission, using new approaches that consider herpesviruses as dynamic, mixed populations of viruses. This project also aims to develop novel, practical, and accessible vaccines to prevent disease. Benefits are expected to arise through prevention of disease in captive marsupial populations, including benefits for conservation efforts and for Australian tourism.

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

The knowledge of the diversity of infectious disease-causing agents in NSW dairy cattle is not comprehensive. Thus, the immediate goal of this proposal is to redress this knowledge gap using untargeted microbial genomic sequencing to characterise and identify known and emerging enteric and respiratory pathogens in dairy calves. We will determine the occurrence and distribution of their microbial species across all NSW dairy regions. This will enable the Australian dairy industry to improve animal health and productivity, and diagnostic capacity, which will allow farmers to make informed management decisions about disease control strategies.
