This project aims to study a family of commensal viruses of mosquitoes called insect-specific flaviviruses that are naturally found in mosquitoes and do not infect or cause disease in vertebrate hosts. Using an innovative approach, this project employs cutting-edge molecular virology approaches to modify these insect-specific flaviviruses to enhance their ability to block the replication of other pathogenic viruses in the mosquito vector. Expected outcome of this project is a bio-control strategy that is complementary to the Wolbachia approach. The anticipated benefits include the advancement of knowledge of insect-specific flaviviruses, and promotion of interdisciplinary research across the fields of Entomology and Virology.Read moreRead less
Transport and innate immune properties of DNA in bacterial nano-sized vesicles. All types of living organisms release nano-sized membrane vesicles or “blebs” which they use for intercellular communication and transport of molecules. This project will determine how bacteria package DNA within these vesicles, how this DNA is transported into host cells and how it triggers immune responses in these cells.
Bacterial filamentation as a survival strategy: a goldmine for the discovery of new cell division regulators. The increasing emergence of untreatable bacterial infections is a serious threat to the health of Australians. Medical advances (organ transplants, chemotherapy), increases in diabetes, and an aging population increase the risk of infections caused by bacteria that are now resistant to most available antibiotics. New classes of antibiotics are urgently needed to treat these infections. T ....Bacterial filamentation as a survival strategy: a goldmine for the discovery of new cell division regulators. The increasing emergence of untreatable bacterial infections is a serious threat to the health of Australians. Medical advances (organ transplants, chemotherapy), increases in diabetes, and an aging population increase the risk of infections caused by bacteria that are now resistant to most available antibiotics. New classes of antibiotics are urgently needed to treat these infections. This project uses a novel approach to identify the mechanisms bacterial cells use to control their growth and avoid attack by our immune system. The research will identify potential targets for the development of new, effective antibiotics to kill multi-resistant bacteria, and ensure Australia's position at the forefront of infection control.Read moreRead less

A recently developed in vitro genetic selection technique has allowed the isolation of oligonucleotides that can bind target molecules with high affinity and specificity. The strategy know as SELEX (Systematic Evolution of Ligands by EXponential enrichment) uses protein biochemistry and PCR technology, with subsequent repeated rounds of selection and amplification, to screen vast libraries of oligonucleotides (RNA or DNA) for their ability to bind target proteins. This procedure will be developed by UNSW in collaboration with the biotech company BTF Plc., Ltd., to be used in two applications. The first is the research interest of UNSW and involves the development of aptamers against hepatitis C virus. The second lies within the interests of BTF and will involve the development of aptamers against the water borne pathogen Cryptosporidium parvum.Read moreRead less

A glycomics approach towards the discovery of novel markers of virus transmission by mosquitoes. The incidence of human and animal diseases caused by mosquito-borne pathogens has increased at an alarming rate globally. This project utilises state-of-the-art glyco-virological approaches and an arbovirus model system to identify new markers associated with virus transmission by mosquitoes. Markers associated with transmission will be identified by establishing global glycan and lectin profiles of ....A glycomics approach towards the discovery of novel markers of virus transmission by mosquitoes. The incidence of human and animal diseases caused by mosquito-borne pathogens has increased at an alarming rate globally. This project utilises state-of-the-art glyco-virological approaches and an arbovirus model system to identify new markers associated with virus transmission by mosquitoes. Markers associated with transmission will be identified by establishing global glycan and lectin profiles of the cells derived from a major mosquito species. This will fill a significant gap in our knowledge of basic transmission mechanisms in mosquitoes. The research strategy is a world-first and the institute is an international leader in this area.

A fundamental study of the role of signal transduction pathways in the regulation of Chlamydia's complex developmental cycle. Chlamydia are unique organisms in the microbial world. They are among the smallest bacteria and yet have a complex two-stage developmental cycle. In addition they are major causes of disease in animals and humans with no vaccines available. We have used the recent flood of full genome sequence data to identify over 30 new cell signalling proteins. By understanding how the ....A fundamental study of the role of signal transduction pathways in the regulation of Chlamydia's complex developmental cycle. Chlamydia are unique organisms in the microbial world. They are among the smallest bacteria and yet have a complex two-stage developmental cycle. In addition they are major causes of disease in animals and humans with no vaccines available. We have used the recent flood of full genome sequence data to identify over 30 new cell signalling proteins. By understanding how these cell signaling proteins are organized into pathways and how this microorganism controls its complex growth and developmental cycle, we will be able to develop novel methods of control. We are at the fore front of international research and therefore uniquely placed to conduct this project.Read moreRead less

Our measurement of global mutation rates will contribute to an understanding of the evolutionary properties of bacteria, the most diverse and successful organisms in the biosphere. Bacterial variation and culture richness contributes not only to ecological processes but also to emerging diseases. The studies will enhance capabilities essential in interpreting the evolution of epidemics and the kinetics of bacterial sweeps in nature. Variation also provides the source material for exploitation of bacterial products such as antibiotics. The results from understanding a complete set of mutational changes through genomic analysis will provide the most direct estimates of variation in evolving bacteria.Read moreRead less
