Development of cloning technology for the Australian Pig Industry. Cloning has the potential to be the most efficient of the reproductive technologies developed for increasing genetic improvement in livestock. Currently up to 5% of cloned embryos develop to term in the pig. This is higher than that reported for cattle and sheep. Moreover the use of this technology in the pig does not appear not to result in the same sorts of problems and losses seen around the time of birth in these species ....Development of cloning technology for the Australian Pig Industry. Cloning has the potential to be the most efficient of the reproductive technologies developed for increasing genetic improvement in livestock. Currently up to 5% of cloned embryos develop to term in the pig. This is higher than that reported for cattle and sheep. Moreover the use of this technology in the pig does not appear not to result in the same sorts of problems and losses seen around the time of birth in these species i.e. the majority of cloned pigs appear normal and are healthy at birth. However before cloning can be used commercially, current efficiencies need to be increased approx two fold for this to be economically viable. The aim of the present study is to improve the efficiency of our current cloning protocol and develop associated technologies such as embryo freezing to facilitate commercialisation. This will ensure that the Australian Pig Industry remains competitive at a pivotal time in its development.Read moreRead less
Identification of Traits and Function by Genomic Matching. Differences between individuals are largely inherited and therefore encoded within the DNA. The challenge is to develop practical means of detecting these differences irrespective of whether they are observable as a phenotype.
Here we focus on livestock. For example, most Australian cattle are horned rather than polled. The inheritance is relatively simple but there is still no DNA test to detect the recessive horning gene.

Here we focus on livestock. For example, most Australian cattle are horned rather than polled. The inheritance is relatively simple but there is still no DNA test to detect the recessive horning gene.
The genomic matching technique is an in-house patented procedure for identifying such DNA differences. If successful, our test will assist industry to eliminate horning and thereby painful dehorning whilst reducing damage to workers and product.

The recently developed adjuvant DCtag utilises unique properties of dendritic cells to boost both cellular and humoral immune responses without tissue damage. This project will identify the mechanisms of immune induction of DCtag using unique properties of our sheep cannulation model. This will allow further optimisation of DCtag adjuvanticity in sheep, which will then be applied to the delivery of a prototype peptide based vaccine against foot and mouth disease virus, a veterinary disease of global importance, hereby increasing Australia's leadership in biotechnology.Read moreRead less

This project aims to develop a technological platform for the fabrication of flexible sensors that enable the detection of food spoilage and life threatening microbial contamination. By engineering stimuli-responsive inks, colorimetric, chemiresistive, and impedimetric sensor arrays will be printed on flexible plastics and paper substrates. The printed sensor arrays will respond to gases and volatile compounds generated from food deterioration and spoilage, microbial pathogen, temperature and pH by a change in their colour or electrical properties, hence providing real-time measurements. The project will enable to design efficient data-driven decision making tools along the supply chain to enhance food safety and reduce food waste. Read moreRead less

Gastrointestinal nematode parasites inflict great losses in sheep and cattle and reliance on anthelmintic drugs for their control is problematic. Vaccination would provide a better alternative but has been difficult to achieve. This proposal aims to apply novel DNA vaccination strategies to the development of parasite vaccines through optimisation of DNA delivery, development of new vaccination vectors and modulation of immune responses by co-delivery of cytokine genes. The results of these studies will not only add a new approach to vaccine development against gastrointestinal parasites but will also contribute to our knowledge of DNA vaccination in large animals.Read moreRead less
Dynamic signaling pathways of dispersal in bacterial biofilms. This Breakthrough Science project will result in an increased understanding of the molecular processes that govern biofilm development and dispersal. While the outcomes will be directly applicable where P. aeruginosa infections continue to cause health-threatening conditions, such as in Cystic Fibrosis chronic infections, it will also be instrumental for the rational design of novel products and strategies to control biofilms of othe ....Dynamic signaling pathways of dispersal in bacterial biofilms. This Breakthrough Science project will result in an increased understanding of the molecular processes that govern biofilm development and dispersal. While the outcomes will be directly applicable where P. aeruginosa infections continue to cause health-threatening conditions, such as in Cystic Fibrosis chronic infections, it will also be instrumental for the rational design of novel products and strategies to control biofilms of other single species or of mixed species populations in many other settings. Countless environmental, industrial and clinical applications will benefit from improved antimicrobial strategies and reduced usage of antibiotics.Read moreRead less

Bacteria will attach to and form biofilms on almost all surfaces. This is particularly a problem in moist environments, including food preparation surfaces, pipe networks (eg. water, oil, and gas), water purification systems. The effects of bacterial biofilms are wide ranging and impact on human health, our capacity to use water resources effectively, and the environment where toxic chemicals are normally used to kill the biofilm. The technologies under development here have the potential to reduce our reliance on toxic chemicals as well as contribute to significant reductions in the cost to purify and distribute vital resources such as water as well as reducing bacterial contamination food surfaces.Read moreRead less

In large animals including humans, DNA vaccination needs to be further improved before becoming a commercial reality, at least partially due to the very low levels of expression in vivo. In vivo electroporation has proven to be an effective way to enhance the level of protein expression and increase DNA vaccine efficacy. We combine enhanced in vivo expression using electroporation with the co-delivery of plasmids encoding cytokines to enhance and modulate DNA vaccine in sheep. We will apply our findings to bovine viral diarrhoea virus (BVDV), both as an animal model for humans and as an economically important diseases of livestock.Read moreRead less
