New vaccines and diagnostics to control viral disease in farmed crocodiles. Infection of farmed crocodiles with West Nile virus (WNV) causes lesions in the skin that render the hides unsuitable for high quality leather products. This results in >$20 million lost revenue to the Australian crocodile industry annually. We have developed a novel technology to generate safe and effective vaccines and diagnostic tests for WNV in animals. We aim to 1) conduct vaccine trials in farmed crocodiles to dete ....New vaccines and diagnostics to control viral disease in farmed crocodiles. Infection of farmed crocodiles with West Nile virus (WNV) causes lesions in the skin that render the hides unsuitable for high quality leather products. This results in >$20 million lost revenue to the Australian crocodile industry annually. We have developed a novel technology to generate safe and effective vaccines and diagnostic tests for WNV in animals. We aim to 1) conduct vaccine trials in farmed crocodiles to determine the optimum dose formulation and immunisation regime to provide long-lived protection against WNV disease; 2) validate pen-side tests to rapidly diagnose WNV infection in crocodiles on farms; and 3) transfer the technology to a manufacturing facility to ensure a commercial supply of the vaccines and diagnostic tests.

Summary
Understanding nutritional interactions for targeted microbiome manipulation. This project aims to identify how microbial communities, known as microbiomes, can be effectively manipulated to the benefit of their host. Microbiome manipulation has been in the spotlight as a potential solution to maintain or improve the health of several hosts, from threatened coral species to livestock and humans, but the development of industry-scale strategies has been slow. This project proposes to chart the nut ....Understanding nutritional interactions for targeted microbiome manipulation. This project aims to identify how microbial communities, known as microbiomes, can be effectively manipulated to the benefit of their host. Microbiome manipulation has been in the spotlight as a potential solution to maintain or improve the health of several hosts, from threatened coral species to livestock and humans, but the development of industry-scale strategies has been slow. This project proposes to chart the nutritional interactions among microorganisms and to identify cascade effects of microbiome manipulation. This will generate fundamental knowledge on the biological processes underlying community stability and malleability, which will ultimately help engineering optimised microbiomes.Read moreRead less
Targeting TGF-beta proteins to control animal reproduction. This project aims to develop a suite of novel biologics to control fertility in female mammals. This project expects to demonstrate that targeting a single class of ovarian proteins will enhance or inhibit egg production. The expected outcomes of this project are to (1) transform the breeding of livestock animals, which should provide significant benefits to the agricultural industry, through increased herd/flock sizes, and (2) provide ....Targeting TGF-beta proteins to control animal reproduction. This project aims to develop a suite of novel biologics to control fertility in female mammals. This project expects to demonstrate that targeting a single class of ovarian proteins will enhance or inhibit egg production. The expected outcomes of this project are to (1) transform the breeding of livestock animals, which should provide significant benefits to the agricultural industry, through increased herd/flock sizes, and (2) provide a non-surgical method of contraception in companion/feral species, which should address the large unmet need for fertility control in these animals.

Development of electrophoretic cell sorters. The aim of this research is to develop the next generation of cell sorters to scale production of viable sperm and other cell types. Our approach is to understand the factors that control the migration of cells in an electric field so that we can design large-scale devices to purify cells using electrophoretic separation. The outcomes of this research enable large-scale production of viable sperm for human and animal-assisted conception, benefiting in ....Development of electrophoretic cell sorters. The aim of this research is to develop the next generation of cell sorters to scale production of viable sperm and other cell types. Our approach is to understand the factors that control the migration of cells in an electric field so that we can design large-scale devices to purify cells using electrophoretic separation. The outcomes of this research enable large-scale production of viable sperm for human and animal-assisted conception, benefiting infertile couples and the livestock breeding industry. Successful development of an efficient cell separation technology would add significant commercial value to the Australian biomanufacturing sector. Read moreRead less
The immune response as a determinant of female reproductive investment. Aims: This project will define how ‘cryptic female choice’ affects reproductive outcomes through immune recognition of embryo histocompatibility genes, to modulate maternal nutrient provision and fetal growth.
Significance: The research will tackle an important knowledge gap in animal reproduction science, where poorly-understood male-female compatibility effects cause variation in breeding efficiency with major economic an ....The immune response as a determinant of female reproductive investment. Aims: This project will define how ‘cryptic female choice’ affects reproductive outcomes through immune recognition of embryo histocompatibility genes, to modulate maternal nutrient provision and fetal growth.
Significance: The research will tackle an important knowledge gap in animal reproduction science, where poorly-understood male-female compatibility effects cause variation in breeding efficiency with major economic and environmental impact.
Expected outcomes: We expect to generate new understanding of the genes, immune response elements, and vascular changes that explain compatibility effects.
Benefits: The results will inform strategies to improve fertility in livestock animals, and in rare and threatened species.

Investigating a new way in which diet impacts animal biology. This project aims to investigate the importance of a new way in which diet can alter animal biology. High fat or high sugar diets increase the binding of products of metabolism to chromosomes, which can completely alter the way that DNA is packaged and read. This project will use cell culture, rodent and fly models to identify the regions of the genome that are most affected by the new process. The project will also determine whether ....Investigating a new way in which diet impacts animal biology.

This project will use cell culture, rodent and fly models to identify the regions of the genome that are most affected by the new process. The project will also determine whether the cell is harmed, or in fact harnesses the process to control development or metabolism. This project has implications for our understanding of the ways in which genes interact with the environment especially in times of change.Read moreRead less
