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
Improving diagnostic accuracy and treatment options for equine PPID. Equine Pituitary Pars Intermedia Dysfunction (PPID) is a common, chronic and potentially life-threatening disease of older horses and ponies. Although a treatment is available, the disease is poorly understood and there are some concerns that the current diagnostic technology is not delivering accurate results. Thus, this project aims to develop a more accurate diagnostic test for PPID, while exploring the relationship between ....Improving diagnostic accuracy and treatment options for equine PPID. Equine Pituitary Pars Intermedia Dysfunction (PPID) is a common, chronic and potentially life-threatening disease of older horses and ponies. Although a treatment is available, the disease is poorly understood and there are some concerns that the current diagnostic technology is not delivering accurate results. Thus, this project aims to develop a more accurate diagnostic test for PPID, while exploring the relationship between PPID and metabolic syndrome, to generate new insights into the cause and consequences of both diseases. As an added benefit, the project will assist horseracing laboratories to improve their detection methods for peptide doping in younger competition horses.

Increasing amphibian immunity to combat disease causing mass extinction. This project aims to increase amphibian survival to combat the devastating chytrid fungus by identifying resistance genes and increasing their frequency in the host population. The project is interdisciplinary and uses targeted genetic manipulation techniques developed for agriculture to improve disease resistance in wildlife for the first time. Expected outcomes include 1) enhanced international collaborations in comparati ....Increasing amphibian immunity to combat disease causing mass extinction. This project aims to increase amphibian survival to combat the devastating chytrid fungus by identifying resistance genes and increasing their frequency in the host population. The project is interdisciplinary and uses targeted genetic manipulation techniques developed for agriculture to improve disease resistance in wildlife for the first time. Expected outcomes include 1) enhanced international collaborations in comparative immunology, 2) a comprehensive understanding of immunity to chytridiomycosis, and 3) disease resistant amphibians. The anticipated benefit is ability to apply the optimal method to improve conservation of wildlife threatened by emerging disease, such as marker assisted selective breeding or genetic engineering.Read moreRead less

Summary
Effects of environmental heat stress on male fertility in livestock species. This project aims to address the role of ambient heat stress in animal fertility by examining its mechanisms and developing treatments to alleviate its effects. Using an interdisciplinary approach that brings together veterinary sciences, reproductive biology, biochemistry and bioinformatics, the project expects to improve our understanding of how high environmental temperatures lead to reduced fertility, pregnancy loss ....Effects of environmental heat stress on male fertility in livestock species. This project aims to address the role of ambient heat stress in animal fertility by examining its mechanisms and developing treatments to alleviate its effects. Using an interdisciplinary approach that brings together veterinary sciences, reproductive biology, biochemistry and bioinformatics, the project expects to improve our understanding of how high environmental temperatures lead to reduced fertility, pregnancy loss and compromised inheritance in large animals, and to develop effective interventions. The resulting benefits include enhanced productivity and resilience of Australia’s livestock industries in the face of a changing climate.

Developing feasible in situ control of mange disease in wombats. Our goal is the development of feasible in situ control of sarcoptic mange in wombat populations. Globally important, the Sarcoptes scabiei mite infects >100 mammal species and is among the 50 most common human diseases, causing health, welfare and population impacts. This infection is treatable, and we will test a new treatment (fluralaner), develop new models to guide management, and conduct replicated field trials. This will ena ....Developing feasible in situ control of mange disease in wombats. Our goal is the development of feasible in situ control of sarcoptic mange in wombat populations. Globally important, the Sarcoptes scabiei mite infects >100 mammal species and is among the 50 most common human diseases, causing health, welfare and population impacts. This infection is treatable, and we will test a new treatment (fluralaner), develop new models to guide management, and conduct replicated field trials. This will enable science-based guidelines, advancing disease control, local eradication, and regulatory approval for wombats. Our research framework is adaptable to other mange-impacted species, and advance methods and theory for control of treatable disease in wildlife.Read moreRead less
Effectiveness of Antimicrobial Stewardship in Australian Veterinary Clinics. Antimicrobial resistance threatens Australians' health, Australia's animal health and its reputation for providing safe and reliable food. Overuse of antimicrobials is a driver of antimicrobial resistance. This project aims to address the overuse of antimicrobials in animals by implementing antimicrobial stewardship in veterinary practices and developing methods of antimicrobial use surveillance. It is the first compreh ....Effectiveness of Antimicrobial Stewardship in Australian Veterinary Clinics. Antimicrobial resistance threatens Australians' health, Australia's animal health and its reputation for providing safe and reliable food. Overuse of antimicrobials is a driver of antimicrobial resistance. This project aims to address the overuse of antimicrobials in animals by implementing antimicrobial stewardship in veterinary practices and developing methods of antimicrobial use surveillance. It is the first comprehensive study to address and assess inappropriate use of antimicrobials in veterinary medicine- and is expected to improve quality use of antimicrobials by veterinarians and prolong the efficacy of antimicrobials in veterinary medicine. This presents a critical step in reducing community exposure to antimicrobial resistance.Read moreRead less
