Epidemiology and pathogenesis of chytridiomycosis in Australian frogs. Strong evidence exists that chytridiomycosis is an introduced disease of amphibians that has caused mass mortality resulting in amphibian population declines and extinctions. Epidemiologic studies will include i) field and experimental studies to determine mortality rates, transmission rates, differences in species susceptibility, and persistence of the pathogen as a saprobe, and ii) molecular epidemiology of fungal strains t ....Epidemiology and pathogenesis of chytridiomycosis in Australian frogs. Strong evidence exists that chytridiomycosis is an introduced disease of amphibians that has caused mass mortality resulting in amphibian population declines and extinctions. Epidemiologic studies will include i) field and experimental studies to determine mortality rates, transmission rates, differences in species susceptibility, and persistence of the pathogen as a saprobe, and ii) molecular epidemiology of fungal strains to examine spread and origin. Pathogenicity studies will be aimed at how chytridiomycosis causes death in frogs. The results will be significant for the conservation of amphibians worldwide and in improving our understanding of diseases in free-living animals.Read moreRead less
Ecological-epidemiological models of feral swamp buffalo control in northern Australia. This research is locally, nationally and internationally significant because it 1) improves the capacity of the Northern Territory and its traditional aboriginal owners to manage together this prevalent species in an effort to minimise disturbance to native flora and fauna and to understand the long-term implications of continued proliferation, 2) provides a nationally relevant system to monitor and project t ....Ecological-epidemiological models of feral swamp buffalo control in northern Australia. This research is locally, nationally and internationally significant because it 1) improves the capacity of the Northern Territory and its traditional aboriginal owners to manage together this prevalent species in an effort to minimise disturbance to native flora and fauna and to understand the long-term implications of continued proliferation, 2) provides a nationally relevant system to monitor and project the spread of disease through feral animal populations in Australia, and 3) combines quantitative data and robust analytical tools that can be used as a template for solving many broad-scale feral animal problems around the world.Read moreRead less
Retroviral invasion of the koala genome: Where did it come from and what is it doing now that its there? Although some populations of free-ranging koalas are flourishing, many are in decline as a result of habitat loss and disease. We have shown that a recently identified virus that has infected koalas throughout most mainland Australian populations is associated with high rates of cancer in these animals. This project will study the growth properties of this virus and the mechanism by which it ....Retroviral invasion of the koala genome: Where did it come from and what is it doing now that its there? Although some populations of free-ranging koalas are flourishing, many are in decline as a result of habitat loss and disease. We have shown that a recently identified virus that has infected koalas throughout most mainland Australian populations is associated with high rates of cancer in these animals. This project will study the growth properties of this virus and the mechanism by which it causes cancer in order to provide a foundation for developing intervention strategies for protection of this iconic Australian species.Read moreRead less
Biotechnology and epidemiology to control nodavirus in barramundi aquaculture. Production of farmed barramundi has increased more than 1200% in the NT since 2001 but is threatened by nodavirus infection. Three industry partners, Darwin Aquaculture Centre, Marine Harvest and Berrimah Veterinary Laboratory will collaborate with The University of Sydney to:
1. control nodavirus infection
2. develop new technologies to detect nodavirus using immunoassay and surface enhanced laser desorption ionis ....Biotechnology and epidemiology to control nodavirus in barramundi aquaculture. Production of farmed barramundi has increased more than 1200% in the NT since 2001 but is threatened by nodavirus infection. Three industry partners, Darwin Aquaculture Centre, Marine Harvest and Berrimah Veterinary Laboratory will collaborate with The University of Sydney to:
1. control nodavirus infection
2. develop new technologies to detect nodavirus using immunoassay and surface enhanced laser desorption ionisation mass spectroscopy (SELDI)
3. develop an integrated disease control strategy based on epidemiological survey data, and ensure that it is practical and able to be widely adopted
By this means growth targets for barramundi aquaculture in northern Australia will be achieved.
