Summary
In this project the world’s most effective vaccines against diseases caused by parasites will be translated from the laboratory to the clinic. The vaccines prevent transmission of parasites from livestock animals to humans. During the next 5 years the vaccines will be produced on a large scale and evaluated in field trials. The products of this research program will make a major contribution to reducing the number of people suffering from parasitic cysts.

Summary
Cysticercosis and hydatid disease are caused by infections with the larval stages of tapeworm parasites. They are zoonotic diseases, transmitted to humans from animals. This project aims to develop practical vaccines to assist with the prevention of these diseases in humans. We will vaccinate the parasites' natural animal hosts and, thereby, break the parasite life-cycles, indirectly and inexpensively preventing the diseases being passed to humans.

This project aims to develop practical vaccines to assist with the prevention of both cysticercosis and hydatid disease in humans. The vaccines will be used in the parasites' natural animal hosts, thereby breaking the parasite life-cycle and preventing the diseases being passed to humans. Substantial preliminary research has been undertaken by the applicant, including completion of successful preliminary vaccine trials. This project will optimise the vaccines and complete initial field trials in countries with high rates of disease transmission.Read moreRead less

These diseases are caused by infection with the larval stages of tapeworm parasites which have a worldwide distribution and cause substantial human morbidity and mortality. The parasites are transmitted to humans from animals. Methods for control of transmission of infection currently rely on public education and anthelmintic treatment of animals. These measures are often ineffective and there is an urgent need for new tools to help control transmission of these important diseases. Previous research has shown that the animal hosts of these parasites can be protected from infection by vaccination. Prevention of infection in the parasites' animal hosts has the effect of breaking the parasite life cycle and indirectly removes the source of infection for humans. This project will further develop an existing vaccine against hydatid disease, will develop a new vaccine against cysticercosis and will participate in initial international parasite control campaigns based on application of these vaccines.Read moreRead less

The parasitic disease, schistosomiasis, caused by human bloodflukes of the genus Schistosoma, is a major public health issue in Africa, Latin America and South East Asia. Current control methods are far from ideal, and a comprehensive understanding of the genetic mechanisms which allow schistosomes to grow, develop and survive within their hosts affords the best prospect for identifying new drug and vaccine targets.

Current control methods are far from ideal, and a comprehensive understanding of the genetic mechanisms which allow schistosomes to grow, develop and survive within their hosts affords the best prospect for identifying new drug and vaccine targets. Microarray technology allows simultaneous monitoring of thousands of different genes, and to determine where and when they are active, thus placing the mass of data generated by genome sequencing programs into a biological and functional context. Microarrays provide a unique, cutting-edge, tool for investigating schistosome biology. We have fabricated a microarray representing some 20,000 schistosome genes. We will use this resource to perform large scale monitoring of schistosome gene expression during the parasite's complex life cycle, targetting the regionally important Asian schistosome, Schistosoma japonicum, for study. This will provide the single largest insight into the genetic changes that occur during schistosome development, will greatly further our understanding of the adaptations needed for the growth, development and survival of the parasite, and will identify genes involved in key biological processes, all of which may be exploitable for future interventions and treatments.Read moreRead less
Understanding The Development Of Humoral Immunity To Malaria Merozoites

Summary
We will examine the acquisition of antibody responses to various P. falciparum surface antigens and their association with reduced risk of re-infection and symptomatic malaria in a treatment re-infection study of children from a malaria endemic area of Papua New Guinea. The effector mechanisms by which protective antibodies control parasite burden will be idendify. Defining the antigenic targets and effector mechanisms of immunity is essential for developing anti-malarial vaccines.

Summary
Hydatid disease is a zoonosis caused by the dog tapeworm Echinococcus with millions of people-animals infected. After decades of study, effective treatment remains a major challenge. We will use a combination of recently developed techniques to isolate specific genes associated with Echinococcus differentiation. Understanding how these genes are controlled will increase our sparse knowledge of the developmental biology of this important parasite and provide new clues for more effective therapies

Summary
Leishmaniasis is a global infectious disease affecting millions and killing thousands each year. This project will utilise the recent discovery in Australia of a related pathogen to identify novel parasite genes and pathways involved in virulence in humans. The latest techniques in comparative genomics and molecular biology will identify the genes that cause human disease . Appropriate genes will then be used to develope a novel vaccine using the Australian parasite.

Summary
Invasion of red blood cells is essential for the survival of malaria parasite within the human host. Red blood cell invasion is mediated by recognition of parasite proteins to specific blood surface receptors. My research focuses on understanding these parasite protein-host receptor interactions with emphasis on translating these findings as novel approaches for the prevention and treatment of malaria.

Summary
Parasitic worms (helminths) secrete molecules that possess a remarkable ability to skew the mammalian immune system towards anti-inflammatory responses. We have expoited a novel peptide secreted by helminths, which offers tremendous potential for the development of novel prophylactic and therapeutic treatments for a range of immune-mediated conditions. The overarching aim of this project is to further elucidate the mechanism of action and to determine the peptide’s clinical application.
