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.

Improving the diagnosis, management and control of chlamydial infections in Australian livestock. Chlamydial diseases, such as arthritis and encephalomyelitis, are associated with significant economic losses for Australian livestock producers. Effective surveillance and management of Chlamydia infections is problematic due to: the absence of epidemiological data; the lack of an accurate and easily interpretable diagnostic test; and the lack of an available vaccine. This project aims to evaluate ....Improving the diagnosis, management and control of chlamydial infections in Australian livestock. Chlamydial diseases, such as arthritis and encephalomyelitis, are associated with significant economic losses for Australian livestock producers. Effective surveillance and management of Chlamydia infections is problematic due to: the absence of epidemiological data; the lack of an accurate and easily interpretable diagnostic test; and the lack of an available vaccine. This project aims to evaluate factors associated with chlamydial disease in Australian livestock and thereby improve on-farm diagnosis. With the concomitant development of a chlamydial vaccine for sheep, this project aims to provide veterinarians and producers with important tools to reduce the on-farm impacts of chlamydial disease.Read moreRead less
Carbon nanotube based electrodes for rapid, dry electro-physiological measurements. Optimised electrical sensors with nanotechnology coatings will be developed for a device that farmers can use to pregnancy test their herd without the need for a vet. This will lead to greater improved management of beef and dairy cattle pregnancies and has been estimated to be worth over $100 million per year to the Australian beef industry.
Development of new tools for surveillance of chlamydial infections in sheep. This project aims to improve health in sheep and reduce on-farm losses for Australian producers, by developing new serological tests for chlamydial infections in sheep. These infections can result in significant on-farm losses and loss of trade in the live export industry. Currently, surveillance of chlamydial infections is hindered by outdated serological tools that are unreliable and difficult to interpret. The ser ....Development of new tools for surveillance of chlamydial infections in sheep. This project aims to improve health in sheep and reduce on-farm losses for Australian producers, by developing new serological tests for chlamydial infections in sheep. These infections can result in significant on-farm losses and loss of trade in the live export industry. Currently, surveillance of chlamydial infections is hindered by outdated serological tools that are unreliable and difficult to interpret. The serological tests to be developed aim to be species-specific tests to detect the most important chlamydial sheep pathogens. This in turn endeavours to improve domestic surveillance, reducing on-farm losses and costs, and improve market opportunities for Australian sheep exporters as well as informing veterinary populations on best practice treatment.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
Chemo-prevention of tropical canine parasitoses and vector-borne diseases. This project will determine the prevalence and diversity of established, emerging and novel canine vector-borne agents and endoparasites in a tropical setting by using conventional and next generation molecular diagnostic tools. It will fill an important gap by providing independently-verified evidence on how well canine anti-parasitic products marketed in Australia and Asia by Bayer Animal Health, perform in high-infecti ....Chemo-prevention of tropical canine parasitoses and vector-borne diseases. This project will determine the prevalence and diversity of established, emerging and novel canine vector-borne agents and endoparasites in a tropical setting by using conventional and next generation molecular diagnostic tools. It will fill an important gap by providing independently-verified evidence on how well canine anti-parasitic products marketed in Australia and Asia by Bayer Animal Health, perform in high-infection pressure settings, as a chemo-preventative for these disease agents. Tropical regions spanning northern Australia and Southern Asia are highly conducive to a plethora of canine vector-borne and parasitic pathogens that cause significant morbidity and mortality in dogs. Many of these agents also pose a risk to public health. The outcomes will be directly translated to best-practice guidelines for the advancement of companion animal (and indirectly human) health and welfare.Read moreRead less
The infectome of NSW dairy calves, a genomic microbial surveillance . Infectious diseases are the main cause of disease and mortality in calves. The knowledge of the diversity of infectious disease-causing agents in NSW dairy cattle is not comprehensive. Thus, the immediate goal of this proposal is to redress this knowledge gap using untargeted microbial genomic sequencing to characterise and identify known and emerging enteric and respiratory pathogens in dairy calves.

The knowledge of the diversity of infectious disease-causing agents in NSW dairy cattle is not comprehensive. Thus, the immediate goal of this proposal is to redress this knowledge gap using untargeted microbial genomic sequencing to characterise and identify known and emerging enteric and respiratory pathogens in dairy calves. We will determine the occurrence and distribution of their microbial species across all NSW dairy regions. This will enable the Australian dairy industry to improve animal health and productivity, and diagnostic capacity, which will allow farmers to make informed management decisions about disease control strategies.
