The project will be a collaboration between the University of Queensland and PanBio Ltd. We intend to use humanized transgenic mice to produce fully human monoclonal antibodies. Fully human antibodies have great advantages over murine antibodies as diagnostics and therapeutics. These reagents will be used to 1)replace human sera , 2)replace antigens from infectious organisms in a range of diagnostic kits for animal and human infectious disease and 3) as therapeutic leads and 4)to discover vaccine leads. The project will allow production of diagnostic kits where this was previously not feasible or not economically viable (eg. uncommon and/or dangerous animal or human diseases) and will lead to development of novel infectious disease diagnostics and therapeutics.Read moreRead less
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

Synthesis and assembly of bacterial repeat unit polysaccharides. Bacteria make an enormous range of surface polysaccharides. The complexity was first appreciated as antigenic diversity, but we now have hundreds of chemical structures and perhaps a hundred sequences of their gene clusters, but the number in nature must be many thousands. Our knowledge of gene function is growing but is not keeping up with the discovery of new sequences and structures. The aim is to determine structure and functio ....Synthesis and assembly of bacterial repeat unit polysaccharides. Bacteria make an enormous range of surface polysaccharides. The complexity was first appreciated as antigenic diversity, but we now have hundreds of chemical structures and perhaps a hundred sequences of their gene clusters, but the number in nature must be many thousands. Our knowledge of gene function is growing but is not keeping up with the discovery of new sequences and structures. The aim is to determine structure and function of key O antigen processing genes and the functions of a range of glycosyl transferases, and to use the information to generate novel gene clusters to synthesise novel polysaccharidesRead moreRead less
Elucidation of bacterial glycosylytransferase specificity. The benefits are involvement in the growth area of polysaccharide research, with potential for major industrial spin off.

The benefits are involvement in the growth area of polysaccharide research, with potential for major industrial spin off. Polysaccharides are critical in all organisms as signalling, structural and storage compounds. Bacteria make a wide variety with extensive use of unusual sugars, some with uses from oil emulsifiers to food thickeners. The project is on the enzymes that assemble bacterial polysaccharides. We are world leaders in genetics of the gene clusters especially synthesis of the unusual sugars. We now aim to fill a major gap by determining which enzymes make which bonds, leading to options for new gene combinations and novel structures. We have a lead in research in this area and Australia gains if we maintain that lead.Read moreRead less
Control of Protein Attachment and its Optical Detection. Protein array technologies have applications in the rapid diagnosis of disease. Biosensors can detect traces of biohazards. Before widespread implementation of these technologies can occur however, a rapid, sensitive and convenient readout method for the control and readout of attachment of proteins to antibodies is needed. I will use electric fields, combined with array imaging at surface plasmon resonance to achieve this aim. This protei ....Control of Protein Attachment and its Optical Detection.

Helicobacter pylori is the most significant bacterial pathogen in the world, infecting 50% globally. Current treatments are inducing rapid antibiotic resistance and are thus becoming increasingly less effective. The infection is acquired in childhood and new methods to prevent and/or treat the infection, minimising acquisition of antibiotic resistance are urgently required. This project seeks to develop new ways of doing this that combine novel antibacterials with techniques to deliver them (and monitor this delivery) as well as modify the complex protective habitat in the stomach.Read moreRead less
Mammalian chitinases and gene therapy: new weapons to combat fungal and insect attack in mammals. Plants combat fungal and insect attack by producing chitin degrading enzymes. Related, chitinolytic enzymes have been identified in mammals, but their functions are unclear. We found that chitinases from human macrophages inhibited fungal growth. We hypothesise that, like plants, mammalian chitinases are produced to fight chitin containing pathogens. We will transform cells with a chitotriosidase ge ....Mammalian chitinases and gene therapy: new weapons to combat fungal and insect attack in mammals. Plants combat fungal and insect attack by producing chitin degrading enzymes. Related, chitinolytic enzymes have been identified in mammals, but their functions are unclear. We found that chitinases from human macrophages inhibited fungal growth. We hypothesise that, like plants, mammalian chitinases are produced to fight chitin containing pathogens. We will transform cells with a chitotriosidase gene and encapsulate them, creating bioreactors secreting chitinases. Therapeutic effects will be tested by grafting bioreactors to mice inoculated with Aspergillus. The research is a new approach to fighting chitin containing pathogens, with potential applications from parasite infestations in livestock to fungal infections in humans.Read moreRead less
