Molecular approaches to solving current and emerging problems in the epidemiology and diagnosis of Marek's disease in Australia. Marek's disease (MD) is a ubiquitous viral disease of chickens that is currently controlled in meat chickens by blanket vaccination of all chickens. However, as has happened overseas, the efficacy of the HVT vaccine being used in Australia is breaking down resulting in subclinical and clinical losses due to MD. To assist industry deal with this situation we propose to ....Molecular approaches to solving current and emerging problems in the epidemiology and diagnosis of Marek's disease in Australia. Marek's disease (MD) is a ubiquitous viral disease of chickens that is currently controlled in meat chickens by blanket vaccination of all chickens. However, as has happened overseas, the efficacy of the HVT vaccine being used in Australia is breaking down resulting in subclinical and clinical losses due to MD. To assist industry deal with this situation we propose to develop novel molecular methods for the quantification of Marek's disease viruses (MDV) in the host and the environment, to use these methods to design effective early monitoring systems for MD in broilers that predict disease and performance outcomes, and to develop an epidemiological model that will predict the spread and severity of MD as failure of vaccinal protection progresses.Read moreRead less
New Approaches to the Control of Post-Weaning Diarrhoea in Piglets. In Australia, post?weaning diarrhoea (PWD) in piglets is a major constraint to efficient and profitable production. Increasing levels of resistance to dietary antibiotics by gut pathogens such as Escherichia coli, the bacterium implicated in PWD, is a major reason for this problem. This research will identify nutritional means of controlling PWD and increasing production after weaning. This will be achieved by strategic nutritio ....New Approaches to the Control of Post-Weaning Diarrhoea in Piglets. In Australia, post?weaning diarrhoea (PWD) in piglets is a major constraint to efficient and profitable production. Increasing levels of resistance to dietary antibiotics by gut pathogens such as Escherichia coli, the bacterium implicated in PWD, is a major reason for this problem. This research will identify nutritional means of controlling PWD and increasing production after weaning. This will be achieved by strategic nutritional interventions in the pre-weaning and (or) post-weaning periods targeted at reducing bacterial pathogens in the gut. A reduction in PWD will increase the overall efficiency of pig production in Australia and reduce antibiotic use.Read moreRead less
Translating Molecular Pathology Into Cancer Diagnostics

Summary
The aim of this research is focussed on translation of basic science through to the clinic by introducing novel cancer diagnostics and technologies. Other integral aims are to identify new changes in DNA and other cancer cell markers in patients, assess the clinical utility of these as biomarkers (surrogates of cancer behaviour) and to conduct novel clinical trials with newly identified molecular targets of cancer and new therapeutics and combinations to assess their efficacy.
The routes of infection with sheep scrapie and agents that cause related prion diseases. We will define the routes by which the infective agents for scrapie, a debilitating disease of sheep, reach the nervous system after being consumed with food. Scrapie is from the same disease group (prion diseases) as mad cow disease. There would be a large economic cost were prion diseases to infect agricultural animals in Australia, through bioterrorism or accident. An outbreak in sheep could ruin the indu ....The routes of infection with sheep scrapie and agents that cause related prion diseases. We will define the routes by which the infective agents for scrapie, a debilitating disease of sheep, reach the nervous system after being consumed with food. Scrapie is from the same disease group (prion diseases) as mad cow disease. There would be a large economic cost were prion diseases to infect agricultural animals in Australia, through bioterrorism or accident. An outbreak in sheep could ruin the industry, as our export markets would be immediately blocked, and thousands of animals would be killed to stop disease spread. The benefit of clearly understanding how the infective agents reach the nervous system is that this may lead to strategies to intervene, and thus limit the spread and seriousness of infection.Read moreRead less
Conservation, health and disease in the endangered marsupial, the Western Barred Bandicoot (Perameles bougainville). Western Barred Bandicoots are highly endangered marsupials, found in the wild only on Bernier and Dorre islands in Western Australia. Captive breeding and reintroduction efforts, considered essential for survival of this species, are currently hampered by a progressively debilitating, wart-like syndrome and reduced fertility. This project will use pathological, immunohistochemical ....Conservation, health and disease in the endangered marsupial, the Western Barred Bandicoot (Perameles bougainville). Western Barred Bandicoots are highly endangered marsupials, found in the wild only on Bernier and Dorre islands in Western Australia. Captive breeding and reintroduction efforts, considered essential for survival of this species, are currently hampered by a progressively debilitating, wart-like syndrome and reduced fertility. This project will use pathological, immunohistochemical and ultrastructural techniques in combination with novel molecular methods, and lymphocyte proliferation assays to determine the causes and conservation implications of these conditions. The hypothesis is that these conditions are a consequence of a viral or chlamydial infection in immunocompromised animals.Read moreRead less
An immunological and immunogenetic approach to understand and to protect Tasmanian devils against Devil Facial Tumour Disease. The Tasmanian devil is the world's largest living carnivorous marsupial. From an environmental perspective, devils play a fundamental role through scavenging. Dead and dying animals were removed nightly from Tasmania's landscape and therefore decaying carcases did not require removal. Loss of this top order scavenger will alter the balance of biodiversity and non-native ....An immunological and immunogenetic approach to understand and to protect Tasmanian devils against Devil Facial Tumour Disease. The Tasmanian devil is the world's largest living carnivorous marsupial. From an environmental perspective, devils play a fundamental role through scavenging. Dead and dying animals were removed nightly from Tasmania's landscape and therefore decaying carcases did not require removal. Loss of this top order scavenger will alter the balance of biodiversity and non-native animals (such as foxes, feral cats, crows, and even European wasps) will then compete for this scavenger role. As these animals are non-selective they will also prey on living animals and many of Tasmania's native animals (such as Eastern barred bandicoot, potoroos, quolls etc.) will be seriously threatened and our biodiverse landscape could be irreversibly altered.Read moreRead less
Prevention and treatment of chlamydiosis and cryptococcosis in koalas. This project aims to generate increased understanding of the aetiology and pathogenesis of the two most prevalent and debilitating infectious diseases of koalas to make improved decisions regarding therapeutic intervention, prevention and management. Chlamydiosis, caused by two chlamydial bacteria, affects koala fertility, urinary tract function and eyesight. Cryptococcosis, caused by the fungus Cryptococcus gattii, may resul ....Prevention and treatment of chlamydiosis and cryptococcosis in koalas. This project aims to generate increased understanding of the aetiology and pathogenesis of the two most prevalent and debilitating infectious diseases of koalas to make improved decisions regarding therapeutic intervention, prevention and management. Chlamydiosis, caused by two chlamydial bacteria, affects koala fertility, urinary tract function and eyesight. Cryptococcosis, caused by the fungus Cryptococcus gattii, may result in koala morbidity and death. Planned therapeutic trials, prevention strategies and the development of optimal husbandry strategies will provide knowledge that will lead to reduced koala morbidity through improved understanding of the interactions amongst infectious pathogens, the animal host and the environment.Read moreRead less
