This project aims to optimise the formulation of novel fluke vaccine antigens by constructing combination hybrid recombinant antigens and using a protein adjuvant to improve immunogenicity, and test new antigens expressed in young flukes as vaccines and evaluate their ability to synergise with hybrid vaccines. Fasciola (fluke) infections cause serious economic losses to livestock production and fluke drug resistance threatens control, so new therapies such as a vaccine are needed. These vaccines should be evaluated in cattle trials. The major outcome plan is validation of hybrid antigens for commercial vaccine development for fluke control in cattle, leading to more sustainable beef and milk production in Australia.Read moreRead less
Targeted drug discovery against blood-feeding parasite nematodes of animals. This project aims to identify more sustainable control strategies of nematode parasites of livestock, which cost more than 400 million yearly to the Australian wool and meat industry.

This project aims to identify more sustainable control strategies of nematode parasites of livestock, which cost more than 400 million yearly to the Australian wool and meat industry. The project expects to identify novel nematicides and generate knowledge of the parasite biology using a combination of high-throughput drug discovery screens with cutting-edge OMICs approaches to target a key molecular pathway of importance to the survival of nematodes, namely their blood-feeding behaviour. Expected outcomes of this project include a likely enhancement of international efforts in controlling these parasites as well as nematicides commercialisation. This should provide significant benefits to agricultural producers in Australia and worldwide.

This project will use novel technologies to identify lead vaccine candidates for improved fluke control to sustain agricultural productivity.
Treating Equine Laminitis. This project aims to explore the causes of equine laminitis, and to work with a newly-established Australian biopharma company to develop the world's first anti-laminitis medication. Equine laminitis is a painful, crippling disease of the foot, often necessitating euthanasia, and is the second-most common cause of death in domestic horses. In 2007, a landmark study identified insulin toxicity as a primary cause of laminitis, and subsequent research has identified over- ....Treating Equine Laminitis. This project aims to explore the causes of equine laminitis, and to work with a newly-established Australian biopharma company to develop the world's first anti-laminitis medication. Equine laminitis is a painful, crippling disease of the foot, often necessitating euthanasia, and is the second-most common cause of death in domestic horses. In 2007, a landmark study identified insulin toxicity as a primary cause of laminitis, and subsequent research has identified over-stimulation of the IGF-1 receptor as the most likely mechanism. This project aims to prove that mechanism and to develop an effective treatment.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.

Relationships between insulin resistance, diet and obesity in ponies and horses. There are an estimated 1.2 million horses in Australia, and the horse industry is estimated to contribute over $6.3 billion to the economy. Laminitis is a significant health and welfare problem in Australia, as it is worldwide, causing pain and lameness, loss of use, and sometimes necessitating euthanasia. Laminitis is one of the most common reasons for horse owners to seek veterinary attention, and diet and obesity ....Relationships between insulin resistance, diet and obesity in ponies and horses. There are an estimated 1.2 million horses in Australia, and the horse industry is estimated to contribute over $6.3 billion to the economy. Laminitis is a significant health and welfare problem in Australia, as it is worldwide, causing pain and lameness, loss of use, and sometimes necessitating euthanasia. Laminitis is one of the most common reasons for horse owners to seek veterinary attention, and diet and obesity increasingly predispose to this condition. Since treatment of laminitis is difficult, prevention is crucial. The outcomes from this project will include the provision of more specific advice on dietary and exercise management to vets and horse owners to reduce the incidence and impact of laminitis on the horse industry.Read moreRead less

Chlamydial infection of the eyes is a significant cause of disease and death in koalas, contributing to the ongoing decline of this native species. Little is known about what influences the outcome of these infections, challenging efforts to manage and control koala chlamydial blindness. This project aims to evaluate whether differences in the infecting Chlamydia pecorum strains or the koala immune response, are associated with the outcome of chlamydial ocular infection. In addition to helping us to understand and prevent blindness in koalas, this project should significantly expand our knowledge of the koala immune system and generate an array of koala immunological assays, outcomes that may benefit all koala conservation efforts.Read moreRead less
