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 Currently, surveillance of chlamydial infections is hindered by outdated serological tools that are unreliable and difficult to interpret.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 Currently, surveillance of chlamydial infections is hindered by outdated serological tools that are unreliable and difficult to interpret.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
Biotechnology applications in the veterinary pharmaceutical industry: Pharmacological manipulation of ovarian function in domestic animals. The purpose of this research is to develop a humane, simple, safe, effective means of sterilizing female domestic animals without the need for surgical intervention. This novel experimental strategy is to target the supply of dormant eggs in the ovaries of female mammals. Every female mammal is born with a finite supply of eggs in the ovarian cortex. These c ....Biotechnology applications in the veterinary pharmaceutical industry: Pharmacological manipulation of ovarian function in domestic animals. The purpose of this research is to develop a humane, simple, safe, effective means of sterilizing female domestic animals without the need for surgical intervention. This novel experimental strategy is to target the supply of dormant eggs in the ovaries of female mammals. Every female mammal is born with a finite supply of eggs in the ovarian cortex. These cells cannot divide and so when this store is exhausted, reproduction ceases. Our strategy is to develop pharmaceutical reagents that will destroy this dormant egg population, thereby rendering the animals instantaneously and irreversibly infertile.Read moreRead less
Devil Facial Tumour Disease: Cytogenetic Clues to Transmission and Development. Devil Facial Tumour Disease is a fatal cancer that is decimating Tasmanian devils. Preliminary work suggests that tumours from different animals have identical sets of highly abnormal chromosomes, including a giant marker chromosome. We will use DNA probes to 'paint' abnormal tumour chromosomes to discover markers for diagnosis, and identify genes contributing to tumour development and immune suppression. Most import ....Devil Facial Tumour Disease: Cytogenetic Clues to Transmission and Development. Devil Facial Tumour Disease is a fatal cancer that is decimating Tasmanian devils. Preliminary work suggests that tumours from different animals have identical sets of highly abnormal chromosomes, including a giant marker chromosome. We will use DNA probes to 'paint' abnormal tumour chromosomes to discover markers for diagnosis, and identify genes contributing to tumour development and immune suppression. Most importantly, we will test our hypothesis that tumours all arose from a single ancestral cancer cell that is transmitted between animals. A cellular transmission has frightening implications for spread of disease, but will allow us to develop appropriate therapeutic strategies to save a unique Australian marsupial from extinction.Read moreRead less
The molecular basis for oocyst and cyst wall formation in apicomplexan parasites. Apicomplexan parasites such as Eimeria, Neospora, Toxoplasma and Plasmodium are single celled organisms - protozoa - that cause some of the most serious infectious diseases of livestock and humans ever known. Transmission of these parasites is dependent on their ability to encase themselves in protective structures known as oocyst or cyst walls. These walls are resistant to harsh environmental conditions, chemicals ....The molecular basis for oocyst and cyst wall formation in apicomplexan parasites. Apicomplexan parasites such as Eimeria, Neospora, Toxoplasma and Plasmodium are single celled organisms - protozoa - that cause some of the most serious infectious diseases of livestock and humans ever known. Transmission of these parasites is dependent on their ability to encase themselves in protective structures known as oocyst or cyst walls. These walls are resistant to harsh environmental conditions, chemicals and attack by the immune system. We will discover and characterise the molecular basis for cyst wall formation. This fundamental knowledge will be the building block for new, highly specific drugs and vaccines to control these extremely important pathogens.Read moreRead less
Immunological mechanisms underlying the protective immune responses induced by botulinum oil adjuvanted vaccine. Botulism is recognised as an important bacterial pathogen in commercial beef cattle in Australia and around the world. Development of affective, well-researched vaccine against Clostridium botulinum is a high priority for the cattle industry. A novel oil adjuvanted vaccine (Singvac from Fort Dodge Pty Ltd) has advantage over conventional vaccines as it provides full protection follo ....Immunological mechanisms underlying the protective immune responses induced by botulinum oil adjuvanted vaccine. Botulism is recognised as an important bacterial pathogen in commercial beef cattle in Australia and around the world. Development of affective, well-researched vaccine against Clostridium botulinum is a high priority for the cattle industry. A novel oil adjuvanted vaccine (Singvac from Fort Dodge Pty Ltd) has advantage over conventional vaccines as it provides full protection following a single administration. The aims of this study are to investigate the immunological mechanisms underlying the protective response by this novel vaccine using bovine and murine models. This study will discover new control measures for botulism in Australia.Read moreRead less
What role does wildlife play in emergency disease? The case of the feral pig. Wildlife populations have been responsible for many disease emergencies with economic and human health impacts, but our current understanding limits their management. This project focuses on the feral pig, an introduced wildlife species. It will develop an understanding of disease spread in feral pigs and from feral pigs to cattle. Using feral pig disease genetics, climate and environmental data, disease spread models ....What role does wildlife play in emergency disease? The case of the feral pig. Wildlife populations have been responsible for many disease emergencies with economic and human health impacts, but our current understanding limits their management. This project focuses on the feral pig, an introduced wildlife species. It will develop an understanding of disease spread in feral pigs and from feral pigs to cattle. Using feral pig disease genetics, climate and environmental data, disease spread models will be developed. These models will be used to better manage emergency disease outbreaks in feral pigs and other wildlife species. This project will deliver practical outcomes, such as the best method of discovering disease and the most effective methods to control emergency animal diseases in wildlife and domestic animals.Read moreRead less
