In Australia, liver fluke disease caused by Fasciola hepatica causes major economic losses to livestock production. Triclabendazole is the most effective drug for parasite control, however, resistance to this drug has emerged and continues to spread in Australia. This project expects to create a novel resource to identify new drug targets, generate new knowledge about the genetic composition of F. hepatica populations and unravel the genetic determinants underlying triclabendazole resistance. The curation of functionally-annotated genetic data for F. hepatica populations will underpin the development of diagnostic tests, drugs and vaccines to deliver a new generation of intervention strategies to control liver fluke disease.Read moreRead less
Functional identification of vaccine targets in pathogenic mycoplasmas. Mycoplasmas are important bacterial pathogens in domestic animals that are incompletely controlled by current vaccines. As a result current control measures for the diseases they cause rely on ongoing treatment with antibiotics. This project will aim to use functional genomics and metabolomics to determine the function of specific surface proteins of a model mycoplasma to identify targets for novel approaches to vaccines aga ....Functional identification of vaccine targets in pathogenic mycoplasmas. Mycoplasmas are important bacterial pathogens in domestic animals that are incompletely controlled by current vaccines. As a result current control measures for the diseases they cause rely on ongoing treatment with antibiotics. This project will aim to use functional genomics and metabolomics to determine the function of specific surface proteins of a model mycoplasma to identify targets for novel approaches to vaccines against these pathogens, and to then assess the potential for inclusion of these proteins in vaccines. Ultimately this will lead to improved vaccines against these important pathogens, improving agricultural productivity and reducing the use of antibiotics in intensively raised livestock.Read moreRead less

This project intends to examine the effect of antibiotic treatment, killed vaccines and immunosuppressive viruses on the protective immunity induced by a model novel vaccine against the important poultry pathogen Mycoplasma gallisepticum. The continued circulation of pathogenic mycoplasmas in intensively managed animals is a major animal health problem. Live attenuated vaccines could reduce disease, but we have limited understanding of the best conditions for their use. This project will generate data to guide both use and development of live mycoplasma vaccines. It is expected to have significant impacts on animal health, welfare and production, and public health by reducing the use of antibiotics to control mycoplasmoses.Read moreRead less
Virulence determinants influencing re-emergence of a complex RNA virus. This project intends to examine the effects that specific genes in naturally occurring recombinants have on their capacity to cause disease and spread between chickens. Coronaviruses are major pathogens of domestic animals throughout the world. Recurrent re-emergence of the coronavirus of chickens, infectious bronchitis virus, has been associated with recombination between wild type viruses and vaccine viruses, but the facto ....Virulence determinants influencing re-emergence of a complex RNA virus. This project intends to examine the effects that specific genes in naturally occurring recombinants have on their capacity to cause disease and spread between chickens. Coronaviruses are major pathogens of domestic animals throughout the world. Recurrent re-emergence of the coronavirus of chickens, infectious bronchitis virus, has been associated with recombination between wild type viruses and vaccine viruses, but the factors influencing this, and in particular the selective advantages genes from vaccine viruses confer on these recombinants, are unknown. The ultimate aim of the project is to identify both novel vaccines and alternative management strategies that might reduce the frequency of re-emergence of this virus and other coronaviruses.Read moreRead less
Novel genomic technologies to improve fertility in northern beef cattle. This project aims to develop new genomic technologies to enable accelerated improvement of cow fertility. Increased global demand for beef is driving northern Australian beef enterprises to develop innovative ways to increase productivity.

This project aims to develop new genomic technologies to enable accelerated improvement of cow fertility. Increased global demand for beef is driving northern Australian beef enterprises to develop innovative ways to increase productivity. A substantial industry challenge is poor fertility of cows, with weaning rates frequently less than 40%. The expected outcomes of this project are an improvement in weaning rates to enable accelerated genetic gain for fertility in these enterprises by delivering a low cost array, which assays thousands of DNA variants affecting fertility simultaneously. This should provide significant benefits such as a new genomic prediction method informed by gene expression data from a unique resource of Brahman cattle with exceptionally high fertility, generating significant industry benefits.Read moreRead less

Network modelling nationally important emerging infectious diseases. The project aims to develop decision-support tools for emerging infectious disease outbreaks that build on recent advances in gene sequencing and predictive modelling.

The project aims to develop decision-support tools for emerging infectious disease outbreaks that build on recent advances in gene sequencing and predictive modelling. Infectious disease transmission depends on the proximity and attributes of infectious and susceptible animals, evolution of the host-pathogen relationship and environmental influences. Recent changes in these have led to a series of major outbreaks with impacts on animal health, productivity and trade. New decision-support tools are required to combine genetic sequences with epidemiological data early in large outbreaks. The intended outcome of the project is that the models developed may enable appropriate and timely intervention and reduce impacts in future outbreaks.Read moreRead less

This project aims to optimise the formulation of novel fluke vaccine antigens by constructing combination hybrid recombinant antigens and using a protein adjuvant to improve immunogenicity, and test new antigens expressed in young flukes as vaccines and evaluate their ability to synergise with hybrid vaccines. Fasciola (fluke) infections cause serious economic losses to livestock production and fluke drug resistance threatens control, so new therapies such as a vaccine are needed. These vaccines should be evaluated in cattle trials. The major outcome plan is validation of hybrid antigens for commercial vaccine development for fluke control in cattle, leading to more sustainable beef and milk production in Australia.Read moreRead less
Identification of causal variants for complex traits. The aim of this project is to identify causal variants for complex traits in cattle and humans. Although most important traits in agriculture, medicine and evolution are complex traits, very few of the genetic variants affecting these traits are known and this undermines our understanding of how genetic variants affect a trait and practical uses of this knowledge. Huge datasets of individuals with genome sequence and phenotypes and new statis ....Identification of causal variants for complex traits. The aim of this project is to identify causal variants for complex traits in cattle and humans. Although most important traits in agriculture, medicine and evolution are complex traits, very few of the genetic variants affecting these traits are known and this undermines our understanding of how genetic variants affect a trait and practical uses of this knowledge. Huge datasets of individuals with genome sequence and phenotypes and new statistical methods provide the opportunity to close this gap. The outcome will be identification of many genomic variants causing variation in complex traits. This will benefit scientific understanding of complex traits and the ability to predict traits for individuals from their genome sequence.Read moreRead less
