Integrated management of pathogenic monogenean (flatworm) parasite infections in warm water finfish aquaculture. Sea cage farming of warm water finfish is expanding worldwide, with potential for lucrative aquaculture industries. These, however, are threatened by monogenean (flatworm) parasites that weaken and can kill sea-caged fishes. Current control methods provide only short-term solutions and increase production costs. Monogeneans jeopardize the fledgling kingfish industry in South Austra ....Integrated management of pathogenic monogenean (flatworm) parasite infections in warm water finfish aquaculture. Sea cage farming of warm water finfish is expanding worldwide, with potential for lucrative aquaculture industries. These, however, are threatened by monogenean (flatworm) parasites that weaken and can kill sea-caged fishes. Current control methods provide only short-term solutions and increase production costs. Monogeneans jeopardize the fledgling kingfish industry in South Australia and remain pests in Japanese yellowtail aquaculture (value, AUS$2.4 billion/year). With Australian and Japanese industry partners, our innovative field and laboratory approach will revolutionize management of fish parasites with direct life-cycles. Outcomes include: integrated long-term strategies to manage parasites; lower production costs; ability for new finfish industries to thrive.Read moreRead less
Evaluating host-parasite interplay in individual tissues. The immune system of the host and the infecting parasite has coevolved into a sophisticated balance of power. This project will explore this balance using Schistosoma japonicum infection in sheep and determine immune mechanisms unleashed by the host in various tissues as well as the response of the parasite to these attacks.
Exploitation of a Novel Drug Target for Controlling Animal Trypanosomiasis. Trypanosomiasis greatly reduces livestock productivity in countries where it is endemic and is a threat to livestock and native wildlife in countries such as Australia where it is exotic but there is a risk of entry. New trypanocidal drugs with different modes of action are urgently needed to overcome growing resistance. This project aims to characterise trypanosome tubulin and, with this information, produce new tubulin ....Exploitation of a Novel Drug Target for Controlling Animal Trypanosomiasis. Trypanosomiasis greatly reduces livestock productivity in countries where it is endemic and is a threat to livestock and native wildlife in countries such as Australia where it is exotic but there is a risk of entry. New trypanocidal drugs with different modes of action are urgently needed to overcome growing resistance. This project aims to characterise trypanosome tubulin and, with this information, produce new tubulin-binding compounds for assessment in vitro and in vivo. Upon completion of the project it is expected that drug binding sites on trypanosome tubulin will be characterised and at least one candidate for clinical trials identified.Read moreRead less
Artificial intelligence to explore and combat eukaryotic pathogens. 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 interacti ....Artificial intelligence to explore and combat eukaryotic pathogens. 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
Deciphering the molecular mechanisms of parasite-host interactions. The completion of genome projects for several helminths of veterinary significance has provided novel insights into the fundamentals of helminth biology. One outcome is the identification of microRNAs, a subclass of small regulatory RNAs which in plants and mammalian cells control diverse biological processes at the posttranscriptional level. We have discovered the presence of helminth miRNAs within host cells with the ability t ....Deciphering the molecular mechanisms of parasite-host interactions. The completion of genome projects for several helminths of veterinary significance has provided novel insights into the fundamentals of helminth biology. One outcome is the identification of microRNAs, a subclass of small regulatory RNAs which in plants and mammalian cells control diverse biological processes at the posttranscriptional level. We have discovered the presence of helminth miRNAs within host cells with the ability to mimic mammalian miRNAs to modulate innate immune responses. This project will discover how helminths hijack the mammalian miRNA machinery to regulate host gene expression and thus support long-term infection. The outcomes will highlight new avenues for the control of these persistent worm infections.Read moreRead less
Harnessing the genome of the Australian paralysis tick to develop effective control products. This project aims to examine the potent cocktail produced by the salivary gland of Australia's paralysis tick. The paralysis tick continues to cause severe illness and deaths for companion pets with up to 100,000 cases of toxicoses per year. This project aims to develop new safe treatments and/or preventative vaccines.
Toward novel approaches for the control of parasitic nematodes via genomics/phenomics. The control of economically important parasitic worms of livestock relies heavily on the use of chemical compounds (anthelmintics). Their excessive and uncontrolled use has led to serious anthelmintic resistance problems in parasites, so that many treatments are no longer effective, and also to residue problems in meat, milk and the environment. We will use 'cutting edge' technologies to provide unique insight ....Toward novel approaches for the control of parasitic nematodes via genomics/phenomics.

Their excessive and uncontrolled use has led to serious anthelmintic resistance problems in parasites, so that many treatments are no longer effective, and also to residue problems in meat, milk and the environment. We will use 'cutting edge' technologies to provide unique insights into the molecular processes of parasite growth and reproduction, to develop safe and sustainable intervention strategies for parasites. The project will provide a unique technology platform and a skills base in parasite genomics and will generate significant intellectual property.Read moreRead less

Results of recent DNA sequencing projects have allowed us to predict the presence of neuropeptides in the worms of sheep. The aim of this project is to elucidate the steps in the action of these peptides, in particular, those that cause muscle contraction. By understanding the action of these peptides we hope to identify targets against which new drugs for parasite control can be developed.Read moreRead less
