Coproantigen detection tests for diagnosis of intestinal parasitic nematode infection. The aim of this project is to develop new tests for detection of hookworm and Strongyloides, two common intestinal worm infections of humans. These tests offer the potential to replace current tests, namely stool microscopy and serodiagnosis, both of whose performance is unsatisfactory due to deficiencies in sensitivity, specificity and operator convenience. The tests will rely on monoclonal antibodies to dete ....Coproantigen detection tests for diagnosis of intestinal parasitic nematode infection. The aim of this project is to develop new tests for detection of hookworm and Strongyloides, two common intestinal worm infections of humans. These tests offer the potential to replace current tests, namely stool microscopy and serodiagnosis, both of whose performance is unsatisfactory due to deficiencies in sensitivity, specificity and operator convenience. The tests will rely on monoclonal antibodies to detect parasite products in stool. Such testing technology is amenable to configuration in a robust format, suitable for large-scale manufacture. Given the worldwide prevalence of these parasites, the tests will have a market potential of international significance.Read moreRead less

MOLECULAR APPROACHES TO OVERCOME SCABIES AND ASSOCIATED DISEASE. Scabies causes childhood pyoderma predisposing to severe disease in later life. It is a major increasing health burden in Indigenous people of Northern Australia. Drug resistance is developing in mites and bacteria. The lack of clinical material has hampered molecular research and this work will use comparative genomics of parasitic and free living mites and microbiome analysis to understand fundamental aspects of mite biology and ....MOLECULAR APPROACHES TO OVERCOME SCABIES AND ASSOCIATED DISEASE. Scabies causes childhood pyoderma predisposing to severe disease in later life. It is a major increasing health burden in Indigenous people of Northern Australia. Drug resistance is developing in mites and bacteria. The lack of clinical material has hampered molecular research and this work will use comparative genomics of parasitic and free living mites and microbiome analysis to understand fundamental aspects of mite biology and pathogenesis. The understanding of proteins that are essential for mite survival and interfere with host defences will allow the informed design of peptide inhibitors as a new strategy to develop alternative treatment options.Read moreRead less
Understanding the dynamics of malaria infection. Malaria infection kills around one million patients each year and this project involves an interdisciplinary team who will directly measure how the parasite grows and is killed by the immune system. A better understanding of parasite growth and control will help develop better drugs therapy and vaccination for this important infection.
New drugs for malaria that target histone deacetylases. There is no vaccine for malaria and current drugs are failing, contributing to millions of malaria-related deaths each year. The aim of this project is to develop new drugs to address this significant global health issue. This project will focus on drugs that act in novel ways to existing malaria drugs by targeting enzymes that are involved in altering gene expression in the parasite. These kinds of enzymes are recognised drug targets in ot ....New drugs for malaria that target histone deacetylases. There is no vaccine for malaria and current drugs are failing, contributing to millions of malaria-related deaths each year. The aim of this project is to develop new drugs to address this significant global health issue. This project will focus on drugs that act in novel ways to existing malaria drugs by targeting enzymes that are involved in altering gene expression in the parasite. These kinds of enzymes are recognised drug targets in other diseases such as cancer. The outcomes of this project will include advances in malaria drug development that build on Australian drug discovery efforts, seeding further funding opportunities from industry and other sources and contributing research training and capacity building in Australia.Read moreRead less

Insect age: an ecological genomics approach to understanding host-parasite interactions. The importance of insect age (or the age structure of a population of insects) in understanding relationships between insects and their abiotic and biotic environment has been stressed in many theoretical studies but seldom directly tested. This is because few tools exist that can accurately measure the age of a wild-caught insect with any accuracy. In this proposal we plan to use a genomics approach to deve ....Insect age: an ecological genomics approach to understanding host-parasite interactions. The importance of insect age (or the age structure of a population of insects) in understanding relationships between insects and their abiotic and biotic environment has been stressed in many theoretical studies but seldom directly tested. This is because few tools exist that can accurately measure the age of a wild-caught insect with any accuracy. In this proposal we plan to use a genomics approach to develop tools that can be used to efficiently determine the age of an insect and then apply these tools to better understand the relationship between insect age and the ability of an insect to transmit pathogens to humans, livestock or plants. These tools will also have future applicability in developing new approaches to control insect transmitted disease as well as provide methodology to determine the effectiveness of current control programs that seek to kill pest insect populations of agricultural or public health significance.Read moreRead less
Red Cell Polymorphisms and Malaria. Certain red blood cell disorders have been associated with innate protection against malaria infection. However many early studies were inconclusive. We intend to carry out a comprehensive study to investigate the effect of red blood cell differences on the invasion and/or growth of Plasmodium falciparum in vitro using improved techniques. Identification of red cell components involved in interaction with P.falciparum would give a better understanding of host ....Red Cell Polymorphisms and Malaria. Certain red blood cell disorders have been associated with innate protection against malaria infection. However many early studies were inconclusive. We intend to carry out a comprehensive study to investigate the effect of red blood cell differences on the invasion and/or growth of Plasmodium falciparum in vitro using improved techniques. Identification of red cell components involved in interaction with P.falciparum would give a better understanding of host parasite interactions which may in turn suggest novel approaches or pathways to persue. This may eventually lead to the development of novel therapeutics.

Resistance to pediculicides in head lice, Pediculus humanus var. capitis. The number of children with head lice in countries like Australia is increasing. One factor that promotes lice is resistance to pesticides. Yet until now resistance has not been studied in Australia. We propose a new approach to studying resistance: "field" tests by school nurses and other health workers. Existing tests require lice to be sent alive to labs in cities. Our test will, if successful, allow people in the ....Resistance to pediculicides in head lice, Pediculus humanus var. capitis. The number of children with head lice in countries like Australia is increasing. One factor that promotes lice is resistance to pesticides. Yet until now resistance has not been studied in Australia. We propose a new approach to studying resistance: "field" tests by school nurses and other health workers. Existing tests require lice to be sent alive to labs in cities. Our test will, if successful, allow people in the "field" to test lice. Expected outcomes are: (i) scientific information on resistance to pediculicides in head lice, and thus, improved control of head lice; (ii) reduced exposure of children to pesticides; and (iii) a strategic alliance between six organisations that should outlive the project.Read moreRead less
