The revolution in artificial intelligence (AI) provides unprecedented opportunities for integrative analyses of complex multi-omics data sets and for creating radically new strategies to control some of the world’s most serious animal diseases. In a strong partnership with international experts, we will use AI-based methods to make major conceptual advances in our understanding of eukaryotic pathogens and host-pathogen interactions, discover the "choke-points" in biological pathways, and develop novel treatments, vaccines and diagnostics. This leap forward will substantially enhance the global profile of pathogen research in Australia, build major capacity in a priority area, and enable access to international research funding and networks.Read moreRead less
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
Development of an amoebic gill disease vaccine to protect Atlantic salmon.

This project aims to identify candidate vaccine antigens and produce an experimental vaccine against amoebic gill disease (AGD) that will benefit the Tasmanian and international Atlantic salmon aquaculture industries. AGD is the most significant health problem affecting Atlantic salmon aquaculture in Tasmania. In the last decade, AGD has become a legitimate health threat to the multibillion dollar global Atlantic salmon industry. A solution is needed before AGD fully establishes itself in the largest Atlantic salmon producing nations. The expected outcome of this project is the development of a commercial vaccine that should significantly benefit the Australian and international aquaculture 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
Defining pathways that control T cell lifespan for long-term immunity. This project will investigate the cellular and molecular pathways regulating lifespan of tissue-resident memory T cells (Trm cells), a non-circulating T cell subset that play a crucial role in the frontline defence against infection. Significantly, how long Trm cells live is paramount to how long immunity is sustained. Using cutting-edge cellular and molecular techniques, the expected outcomes of this project include identifi ....Defining pathways that control T cell lifespan for long-term immunity. This project will investigate the cellular and molecular pathways regulating lifespan of tissue-resident memory T cells (Trm cells), a non-circulating T cell subset that play a crucial role in the frontline defence against infection. Significantly, how long Trm cells live is paramount to how long immunity is sustained. Using cutting-edge cellular and molecular techniques, the expected outcomes of this project include identification of the genes and processes that control lifespan. This should provide significant benefits in the basic knowledge of how longevity of immunity is regulated. This understanding will be useful for future immunotherapeutic applications, such as veterinary or human vaccines requiring maximal duration of immunityRead 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.

A “Goldilocks” live attenuated poultry vaccine for Infectious Coryza. This project aims to develop a safe and effective vaccine for Infectious Coryza using a live-attenuated vaccine approach. Infectious coryza is an acute respiratory disease of chickens and is caused by the bacterial pathogen, Avibacterium paragallinarum. Infectious Coryza can be controlled by appropriate biosecurity practises and this has been successful in the Australian context to date. However, in the USA, Europe and other e ....A “Goldilocks” live attenuated poultry vaccine for Infectious Coryza. This project aims to develop a safe and effective vaccine for Infectious Coryza using a live-attenuated vaccine approach. Infectious coryza is an acute respiratory disease of chickens and is caused by the bacterial pathogen, Avibacterium paragallinarum. Infectious Coryza can be controlled by appropriate biosecurity practises and this has been successful in the Australian context to date. However, in the USA, Europe and other equatorial regions, infectious Coryza remains an unsolved problem. The expected outcome of this project is a cross-serovar protective vaccine to prevent infectious coryza for use in endemic countries and to act as a biosecurity measure to protect Australia's poultry industry against an incursion of this disease.Read moreRead less
