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

Cryptosporidium is an important waterborne agent of diarrhoeal disease in people and animals. Improved methods for accurately detecting viable parasite stages recovered from water are a priority research need for the water industry. They are dependent upon improved in vitro cultivation procedures that can be combined with DNA-based assays for identifying species and strains of Cryptosporidium and closely related protozoa recovered from freshwater. This project addresses these needs in a collaborative study between scientists at Murdoch University with expertise in both in vitro cultivation and genetic characterisation of Cryptosporidium, and scientists from two of the major water utilities in Australia.Read moreRead less

In this project, molecular diagnostic tools will be generated that will improve the ability of testing laboratories to deliver cost-effective virus diagnostic services to seed potato certification authorities in Australia. There will be economic benefits from increased yields of fresh and processing potatoes, higher prices in domestic and export markets, expansion of current and development of new markets, and licensing of tests. There will also be economic and social returns to the broader rural community by better management and control of virus pathogens, and less reliance on environmentally undesirable chemical control measures. The project will provide expert training of two PhD students in practical and molecular plant virology. Read moreRead less

Nematodes are economically important pests of many agricultural and commercially grown plants. We have shown 'proof-of-concept' that plant parasitic nematodes can be identified by protein profiling using MALDI-TOF mass spectroscopy. In this project advanced techniques of proteomics and associated bioinformatics will be used to identify, isolate and characterise proteins that are specific to economically important nematode species and races, and to identify diagnostic proteins or epitopes. The diagnostic proteins will be used to generate specific monoclonal antibodies that will be incorporated into immunochemical 'Lateral Flow' devices. These will provide on-site tests to identify nematodes for growers and quarantine services. Read moreRead less
Brassica genome organisation and evolution: unlocking the potential of using genome-specific repetitive elements for crop improvement. Introgression of chromosome segments from related Brassica species provides an opportunity to develop locally adapted varieties with improved agronomic and quality traits.

Introgression of chromosome segments from related Brassica species provides an opportunity to develop locally adapted varieties with improved agronomic and quality traits. There is a need to understand Brassica genome organisation and how this information can be used for enhancing the efficiency of cultivar development. Dispersed and tandem repetitive DNA sequences provide valuable information on the organisation and evolution of plant chromosomes. Methods for monitoring chromosome segment transfer across Brassica species will be developed based on detecting and quantifying genome-specific repetitive DNA sequences. Australian Brassica improvement programs could benefit from this research by adopting methods to detect chromosome segment transfer during interspecific hybridisation.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.

Exploiting the Arabidopsis genome sequence as a molecular 'toolbox' for Brassica improvement. Australia's position as a major exporter of canola (Brassica napus) is under threat from genetic improvements in yield and quality being made by our international competitors. We will identify genes from Arabidopsis (the 'tool-box') that will be used to increase the speed of selection of new canola varieties with improved oleic acid content, disease resistance, and agronomic traits such as early flower ....Exploiting the Arabidopsis genome sequence as a molecular 'toolbox' for Brassica improvement. Australia's position as a major exporter of canola (Brassica napus) is under threat from genetic improvements in yield and quality being made by our international competitors. We will identify genes from Arabidopsis (the 'tool-box') that will be used to increase the speed of selection of new canola varieties with improved oleic acid content, disease resistance, and agronomic traits such as early flowering and cold tolerance. Genome similarity between Arabidopsis and canola will be exploited to map specific genes from Arabidopsis directly into canola. Based on this knowledge, we will develop gene-specific molecular markers for rapid selection of Australian-adapted canola varieties.Read moreRead less
