Academic staff profile
Dr Brian Jones
Pharmacy and Biomolecular Sciences
Within the broad theme of host-microbe interaction, my team is presently undertaking research at both ends of this spectrum. We utilize a wide array of molecular genetic techniques and systems-level approaches (encompassing metagenomics, metaproteomics and metabolomics) to understand host microbe-interaction from the scale of virulence mechanisms in single species, to the structure, function and health impacts of whole microbial ecosystems.
Catheter associated UTI
Human gut microbiome
The human GI tract is home to a complex microbial ecosystem composed predominantly of bacteria. This is estimated to encompass ~400-800 distinct species in the healthy adult human, and these microbes are now known to play an intimate role in our development and wellbeing. As well as undertaking a range of beneficial functions, the gut microbiome has also been implicated in a number of disease processes including colorectal cancer and inflammatory bowel disorders (IBD). A greater understanding the structure, function, and mechanisms of host-microbe interaction in this community holds the promise of significant advances in health care, including stratified or personalized medicine, and the prevention or treatment of a wide range of intestinal and metabolic disorders. My team is actively pursuing a number of projects aimed at gaining both a fundamental understanding of this ecosystem, as well as elucidating its role in the pathogenesis of colorectal cancer and IBD, and exploiting its biotechnological potential. We have also pioneered the concept and study of the human gut mobile metagenome – defined as the total pool of mobile genetic elements associated with this community, and continue to investigate the role of this flexible gene pool in gut microbiome development and function.
Proteus mirabilis is a common cause of catheter associated urinary tract infections (CAUTI), in patients undergoing long-term bladder management. These devices are used in vast numbers in healthcare systems across the world and CAUTI are the most prevalent hospital acquired infection. P. mirabilis forms dense crystalline biofilms on catheter surfaces, which eventually block urine flow leading to complications such as pyelonephritis, septicemia and endotoxic shock.
We currently have a range of projects underway aimed at understanding the basis of P. mirabilis pathogenesis in the catheterized urinary tract, as well as developing strategies for detection and prevention of these infections. These include defining the genetic basis of biofilm formation and swarming in this organism, understanding of the regulation of gene expression during these complex processes, as well as evaluating bacteriophage based therapies for disease prevention, and aptamer based strategies for rapid point-of-care diagnosis.
