Deciphering the molecular mechanisms of parasite-host interactions. The completion of genome projects for several helminths of veterinary significance has provided novel insights into the fundamentals of helminth biology. One outcome is the identification of microRNAs, a subclass of small regulatory RNAs which in plants and mammalian cells control diverse biological processes at the posttranscriptional level. We have discovered the presence of helminth miRNAs within host cells with the ability t ....Deciphering the molecular mechanisms of parasite-host interactions. The completion of genome projects for several helminths of veterinary significance has provided novel insights into the fundamentals of helminth biology. One outcome is the identification of microRNAs, a subclass of small regulatory RNAs which in plants and mammalian cells control diverse biological processes at the posttranscriptional level. We have discovered the presence of helminth miRNAs within host cells with the ability to mimic mammalian miRNAs to modulate innate immune responses. This project will discover how helminths hijack the mammalian miRNA machinery to regulate host gene expression and thus support long-term infection. The outcomes will highlight new avenues for the control of these persistent worm infections.Read moreRead less
Harnessing the genome of the Australian paralysis tick to develop effective control products. This project aims to examine the potent cocktail produced by the salivary gland of Australia's paralysis tick. The paralysis tick continues to cause severe illness and deaths for companion pets with up to 100,000 cases of toxicoses per year. This project aims to develop new safe treatments and/or preventative vaccines.
Excitatory neuropeptides from nematode parasites of sheep. Internal parasites cause major disease and economic loss in Australian agricultural industries. Control, usually achieved with drugs, is now compromised by drug resistance and new remedies are required. Results of recent DNA sequencing projects have allowed us to predict the presence of neuropeptides in the worms of sheep. The aim of this project is to elucidate the steps in the action of these peptides, in particular, those that cause m ....Excitatory neuropeptides from nematode parasites of sheep.

Control, usually achieved with drugs, is now compromised by drug resistance and new remedies are required. Results of recent DNA sequencing projects have allowed us to predict the presence of neuropeptides in the worms of sheep. The aim of this project is to elucidate the steps in the action of these peptides, in particular, those that cause muscle contraction. By understanding the action of these peptides we hope to identify targets against which new drugs for parasite control can be developed.Read moreRead less

Advancing chicken helminthology for sustainable worm control . Worm infections are a serious disease problem in free-range chicken production systems which now dominate egg production in Australia. This project aims to improve the control of worm infections of chickens by developing new tools for poultry researchers, advisors and farmers to use for this purpose. The project expects to develop novel methods for laboratory-based anthelmintic drug resistance testing, maintenance of defined worm str ....Advancing chicken helminthology for sustainable worm control . Worm infections are a serious disease problem in free-range chicken production systems which now dominate egg production in Australia. This project aims to improve the control of worm infections of chickens by developing new tools for poultry researchers, advisors and farmers to use for this purpose. The project expects to develop novel methods for laboratory-based anthelmintic drug resistance testing, maintenance of defined worm strains and diagnosis of infection. It will also determine the effectiveness of mass treatment in the field and the prevalence of anthelmintic resistance. Use of these tools and information will improve worm control and thus the productivity and welfare of free-range chickens in Australia and worldwide.Read moreRead less
The biosynthesis of structural proteins in parasites. The socio-economic impact of parasitic diseases, in Australia and throughout the world, is enormous- they kill 2-3 million people per year and cost livestock industries billions of dollars per annum. Some are serious food and waterborne threats, such as the coccidia, because they are transmitted from person-to-person via the faecal-oral route, or via ingestion of contaminated water or food, or through the ingestion of cysts in raw or underco ....The biosynthesis of structural proteins in parasites. The socio-economic impact of parasitic diseases, in Australia and throughout the world, is enormous- they kill 2-3 million people per year and cost livestock industries billions of dollars per annum. Some are serious food and waterborne threats, such as the coccidia, because they are transmitted from person-to-person via the faecal-oral route, or via ingestion of contaminated water or food, or through the ingestion of cysts in raw or undercooked meat. They cause diarrhoea, which in some cases, can be life-threatening. We will understand how the coccidia protect themselves as they move from host to host and, through that understanding, develop new ways to control them and eliminate the suffering caused by parasitic diseases.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

Development of a topical treatment to replace surgical mulesing in sheep. 10,800 farms in Australia are sheep farms and a further 30,000 have sheep. Exports of wool earn over $2 billion annually.

If practical alternatives are not found costs will rise compromising the economic viability of many sheep farms.

Mulesing is largely confined to Australian Merino sheep and requires Australian research. If practical alternatives are not found costs will rise compromising the economic viability of many sheep farms. Chemical use on the breech will increase causing environmental contamination. A simple topical alternative to mulesing will allow farmers to economically manage flies and satisfy welfare imperatives. This will support rural communities and sustain Australia's export income from wool.Read moreRead less
