The outcomes of this project will help control disease caused by alphaherpesviruses, including disease in livestock (horses and poultry) and wildlife (kangaroos and wallabies). This will enhance animal health and welfare and will also benefit the associated industries. Livestock industries are critically important to the Australian economy (equine and poultry industries annually contribute approximately $7.7 and $2.6 billion respectively to our GDP). Wildlife species are crucial to Australian ecosystems and feature in the Australian tourism industry. This project is expected to strengthen international research collaborations and further enhance Australia's reputation as a world-class leader in research and biotechnology.Read moreRead less
Development and Assessment of Chimaeric Feline Caliciviruses as Vaccines. Feline caliciviruses are major pathogens of cats worldwide, but current vaccines offer only incomplete protection. This project aims to develop novel recombinant vaccine strains that will generate more cross protective immunity and thus provide greater protection for vaccinated cats.

This project between the animal virology group at Murdoch University and the major supplier of laboratory mice to the Australian research community will produce a sensitive serological test for the detection of mouse parvovirus in laboratory mouse colonies. Widespread infection by this virus has recently been identified in mouse colonies in Australia, and eradication of the virus and future surveillance requires the development of a sensitive serological test amenable to automated high throughput analysis. Eradication of this virus is critical as the virus modulates the immune system of mice and affects the results obtained in mice used for medical research.Read moreRead less
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

This project will develop novel methods for identification of genes involved in virulence of the important avian pathogen Infectious Laryngotracheitis Virus and produce an attenuated, antigenically marked infectious laryngotracheitis virus vaccine strain by specific disruption and deletion of two or more genes in the virusÕs genome.
Infectious laryngotracheitis is a major disease of chickens throughout the world, but current vaccines retain some capacity to cause disease. The development of novel attenuated vaccines will thus enhance control of this important disease of poultry.Read moreRead less
Retroviral invasion of the koala genome: prevalence, transmission and role in immunosuppressive disease. Koalas are a national symbol yet many of their populations are in decline as a result of habitat loss and disease. Lymphoid cancers and opportunistic infections are significant diseases in both captive and wild koala populations. We previously demonstrated that the recently identified koala retrovirus is associated with lymphoid cancer in koalas. This project will determine the distribution o ....Retroviral invasion of the koala genome: prevalence, transmission and role in immunosuppressive disease. Koalas are a national symbol yet many of their populations are in decline as a result of habitat loss and disease. Lymphoid cancers and opportunistic infections are significant diseases in both captive and wild koala populations. We previously demonstrated that the recently identified koala retrovirus is associated with lymphoid cancer in koalas. This project will determine the distribution of the virus in Australia, the mechanism of its spread and its effect on the immune function of koalas. This research will provide a foundation for better management of captive koalas and for conservation of wild koalas.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

This project will generate fundamental new knowledge into the pathogenesis of persistent, chronic viral diseases in a wide range of animal hosts. Furthermore, beak and feather disease virus is listed as a Key Threatening Process under the Endangered Species Protection Act (1992) to at least sixteen endangered Australian bird species. Very little is known about the host-virus interactions that occur during the early stages of infection or why some birds recover yet others develop full blown disease. This project will provide new knowledge that can be used to counteract its effects on current and future endangered species recovery program.Read moreRead less
