Bacterial and host drivers of chlamydial blindness in koalas. Chlamydial infection of the eyes is a significant cause of disease and death in koalas, contributing to the ongoing decline of this native species. Little is known about what influences the outcome of these infections, challenging efforts to manage and control koala chlamydial blindness.

Chlamydial infection of the eyes is a significant cause of disease and death in koalas, contributing to the ongoing decline of this native species. Little is known about what influences the outcome of these infections, challenging efforts to manage and control koala chlamydial blindness. This project aims to evaluate whether differences in the infecting Chlamydia pecorum strains or the koala immune response, are associated with the outcome of chlamydial ocular infection. In addition to helping us to understand and prevent blindness in koalas, this project should significantly expand our knowledge of the koala immune system and generate an array of koala immunological assays, outcomes that may benefit all koala conservation efforts.Read moreRead less
Improved biosecurity through the engineering of microbial ecosystems. This project aims to provide data and understanding that will help develop predictive models for changes in the distribution of drug-resistant bacteria, and surveillance and response programs for key biosecurity threats. Microorganisms, including commensals and pathogens, can live in complex communities in a range of environments including animal hosts. It is now known that these communities (known as microbiomes) can exert a ....Improved biosecurity through the engineering of microbial ecosystems. This project aims to provide data and understanding that will help develop predictive models for changes in the distribution of drug-resistant bacteria, and surveillance and response programs for key biosecurity threats. Microorganisms, including commensals and pathogens, can live in complex communities in a range of environments including animal hosts. It is now known that these communities (known as microbiomes) can exert a profound effect on animal health. This project seeks to understand where antimicrobial resistance genes reside in pig gut microbiotia and how they move between members of this complex microbial community, and to provide information on how probiotics may be used to reduce dependence on antibiotics.Read moreRead less
Microbial sulphatises in the rhizosphere and their control by interactions with plants. Plant-microbe interactions are critical in mobilizing soil sulphur for crop growth. This project will identify the microbes responsible for delivering sulphur to two major Australian crops, and will examine how the plants stimulate this activity in their root zone. The results have potential application for sustainable agriculture in Australia.
Developing a chlamydial vaccine for koalas. Developing a chlamydial vaccine for koalas . This project aims to produce an optimised, safe, field-tested, protective Chlamydia vaccine for koalas. In many regions of Australia, Chlamydia infection severely reduces female koala reproductive rates, threatening the species’ long term survival.

Development of a vaccine to protect koalas against koala retrovirus (KoRV). This project aims to develop a vaccine against koala retrovirus (KoRV) to arrest the increasing loss of animals due to this infection. Along with Chlamydia, KoRV threatens the long-term survival of the koala. KoRV infects over 95 per cent of Australia’s koalas and has been strongly linked to lymphoma and leukemia. Although quarantine and antiretroviral drug treatment are possible control measures, they are impractical in ....Development of a vaccine to protect koalas against koala retrovirus (KoRV). This project aims to develop a vaccine against koala retrovirus (KoRV) to arrest the increasing loss of animals due to this infection. Along with Chlamydia, KoRV threatens the long-term survival of the koala. KoRV infects over 95 per cent of Australia’s koalas and has been strongly linked to lymphoma and leukemia. Although quarantine and antiretroviral drug treatment are possible control measures, they are impractical in the wild, leaving vaccination as the only realistic option. This is valuable for both wild and captive koalas; zoos report high animal losses due to KoRV-associated lymphoma. The main outcome will be a KoRV vaccine which can be combined with a Chlamydia vaccine which is being developed in parallel.Read moreRead less
Development of a safe and immunogenic anti-chlamydia vaccine for the koala. Many koala populations are under threat of extinction from chlamydial disease.The project will develop a chlamydial vaccine and conduct trials in several wild koala populations for safety and effectiveness.
Gating, specificity and regulation of the YggB channel protein from Corynebacterium glutamicum. The proposed research will greatly contribute to our understanding of the functioning of a bacterial membrane channel/transporter, which has played a significant role in biotechnology of commercially important amino acids.

The proposed research will greatly contribute to our understanding of the functioning of a bacterial membrane channel/transporter, which has played a significant role in biotechnology of commercially important amino acids. A direct national benefit will result from establishing collaboration with a leading German laboratory providing expertise in protein biochemistry and molecular microbiology not available in Australia. The acquired knowledge will present an original contribution which will have a strong impact on a very competitive field of molecular microbiology and biotechnology.Read moreRead less
Mapping cell wall and surface structures of Gram-positive cocci. The synthesis of the Gram-positive cell wall and protein transport are fundamental processes, the improved understanding of which will impact across a range of fields including microbiology, biochemistry and biotechnology, and the application and manipulation of Gram-positive bacteria in agriculture, industry and human health.

In the long-term, the analysis of the Gram-positive ExPortal and cell wall will identify proteins that may represent targets for therapeutic intervention. Additionally a precise understanding of the mechanisms of secretion of anchorless proteins will have an important impact in the biotechnology field, as new methodologies for the secretion of recombinant proteins of industrial value is a potential outcome.Read moreRead less

Superresolution fluorescence imaging in microbiology:
This project involves the purchase of new, and upgrade of existing, fluorescence imaging tools to facilitate the study of intracellular processes in microbial systems at significantly higher spatial and temporal resolutions than hitherto possible. Visualisation of the structure and dynamics of intracellular molecular assemblies at maximal resolution is required to understand protein function inside living cells. The new equipment is designed to provide a fast super-resolution imaging system to study the intracellular dynamics of proteins in vitro and a super-resolution microscope to visualise structures and assemblies inside microbes with a resolution of tens of nanometres, putting in vitro biochemistry into the context of a living cell.

THE BIOLOGY OF COLD ADAPTED EXTREMOPHILES: AN INTEGRATED GENOMIC-PROTEIN ANALYSIS APPROACH. Extremophiles are microorganisms that can thrive in otherwise inhospitable environments. Most extremophiles are Archaea; an order of life separate from Bacteria and Eucaryotes. The project will generate the first genome sequence that was initiated in Australia, and the first genome sequence of any cold adapted organism. Associated functional studies include global analyses of protein expression (proteo ....THE BIOLOGY OF COLD ADAPTED EXTREMOPHILES: AN INTEGRATED GENOMIC-PROTEIN ANALYSIS APPROACH. Extremophiles are microorganisms that can thrive in otherwise inhospitable environments. Most extremophiles are Archaea; an order of life separate from Bacteria and Eucaryotes. The project will generate the first genome sequence that was initiated in Australia, and the first genome sequence of any cold adapted organism. Associated functional studies include global analyses of protein expression (proteomics) and mRNA expression using micro-arrays, and work targeted at RNA binding proteins and protein folding systems involved in the thermally sensitive process of protein synthesis. The nature and scope of the work will impact on fundamental cellular processes and provide enormous innovative biotechnological potential.Read moreRead less
