Summary
This project will study how the bacteria that cause infant diarrhoea colonize the intestine and induce disease. We have identified a novel genetic region that allows E. coli to survive and persist in the intestine. Similar genes are also present in closely related organisms. This project will help us to undestand how new diseases evolve and emerge and may lead to the development of new vaccines to protect against infant diarrhoea.
Bacterial Pathogenomics: Whole-genome Sequencing To Investigate Infection Transmission, Pathogenesis And Antibiotic Resistance

Summary
As bacterial superbugs – resistant to multiple antibiotics – dominate the headlines, the pipeline for new antibiotics has all but dried up. High-throughput DNA sequencing heralds a golden opportunity for infectious disease research. By studying the entire collection of genes - the genome - of large numbers of multidrug resistant bacterial strains, we aim to better understand the genetic changes that govern the emergence and global spread of superbugs and translate these findings into the clinic.
Pathogenomics: New Ways To Exploit Genome Sequence Data From Pathogenic Bacteria.

Summary
Bacterial pathogens are locked in an evolutionary battle of survival with their eukaryote hosts. The rapidly evolving genes of medically-important pathogens are generally those required for adaptation to the human host. This project aims to exploit the abundance of available bacterial genome sequences to predict rapid evolution in bacterial pathogens using computational methods. The protein products of such genes offer novel targets for therapeutic intervention.
This program will investigate the strategies used by pathogenic bacteria to cause human diseases. The research will focus on how bacteria initiate infections, how they invade, cause cell and tissue damage and respond to their human host. It will also examine how the host’s innate immune system interacts with these bacteria. The results will provide new insights into host-pathogen interactions and reveal new targets for the development of novel antibacterial drugs and vaccines.
Infectious pathogens invade cells by hijacking cellular pathways, termed endocytosis, that normally internalise material from outside the cell. We will identify the molecular details of these pathways and how they are modulated in response to infection with Salmonella, a leading cause of human gastroenteritis. Such studies are necessary in order to understand host-pathogen interactions so that treatments can be developed targeting the symptoms of infection

Summary
Antibiotic resistance (AR), as highlighted by the WHO, is the most pressing medical need of the 21C – some infections are now untreatable. Our research will focus on the new "superbug" NDM-1 positive E. coli. We will correlate AR and pathogenicity and explore the evolution of these "superbugs" using state-of-the-art sequencing. This research will benefit Australian medicine by predicting timelines of AR epidemics and by conducting the first analyses on the virulence potential of these strains.
Uropathogenic Escherichia coli (UPEC) are a major cause of urinary tract infections (UTI) and sepsis. Recently, a highly virulent clone of UPEC (E. coli ST131) that is resistant to multiple types of antibiotics has emerged worldwide. This project addresses the mechanisms by which E. coli ST131 can colonise the urinary tract and cause disease. The outcomes of this project will be a better understanding of how E. coli ST131 causes disease, and potentially new treatment regimes for UTI.

Understanding The Role Of The Two Major Bacterial Pathogens In The Upper And Lower Airways Of Indigenous Children With Chronic Lung Disease

Summary
Lung infections are a major disease burden worldwide. Indigenous Australians are affected more; adults with severe lung disease can die in their 30s and 40s. These diseases start early, yet no in-depth studies of bacteria causing lung infections in children have been done. Our expert team proposes to use existing lung fluids from nearly 500 children with chronic lung disease (58% Indigenous), and state-of-the-art laboratory methods, to inform the design of vaccines to prevent lung disease.
