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.

Summary
Pathogenic bacteria are master manipulators of the inflammatory signalling pathways designed to thwart them. Understanding how they do this will allow us to develop drugs that limit their ability to infect. We have shown that pathogenic bacteria inject a protein called EspL into human cells to promote the destruction of a family of human proteins, called RIP Kinases (RIPK), that co-ordinate the inflammatory response and aim now to discover how EspL causes RIPK degradation and thereby promotes in ....Pathogenic bacteria are master manipulators of the inflammatory signalling pathways designed to thwart them.

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.

Summary
Antibiotic drugs are essential to treat bacterial infections. However some bacteria have genes that allow them to resist certain drugs, which can be transferred among bacteria to create 'superbugs' that can resist nearly all the drugs we have. This project investigates the transfer of drug resistance genes between Gram negative bacteria (common agents of food poisoning, hospital infection, UTI, etc) and aims to identify the bacteria and genes most important in the spread of superbugs in Australi ....Antibiotic drugs are essential to treat bacterial infections.

Summary
Streptococcus pneumoniae is an significant human pathogen which causes several diseases including pneumonia and meningitis. Treatment of infection involves the use of antibiotics such as penecillin, however, resistant strains are now emerging. This project will address the real need to develop new antibiotics targeting this organism. This is essentially a drug discovery project which exploits a novel means to target Streptococcus pneumoniae.
Infectious diseases plague mankind; with infections responsible for approximately 20% of all deaths worldwide. New strategies are urgently needed and we have positioned our research to address questions around how to forestall bacterial pathogens in the initial phases of invasion of human tissues and provide full understanding of the key molecules on the surfaces of bacterial cells. This fundamental knowledge is crucial to new drugs, vaccines and infection-resistant medical devices.

Bacterial infectious diseases are a serious threat to human health, accounting for over 10 million deaths each year. This multidisciplinary collaborative team is investigating the complex interactions between major disease-causing bacteria and their human hosts, in order to determine how they cause disease.

Understanding Virulence In Staphylococcus Aureus And Impacts On Host Response

Summary
Golden Staph remains an important cause of serious infections in Australian patients. New strategies to combat this disease require a better understanding of how Golden Staph causes disease and escapes the natural human response to infection. This study will provide new insights into how Golden Staph causes disease, and provide a platform for developing new strategies to prevent and treat Golden Staph infections.
Targeting Hypermutable ‘superbugs’ In Chronic Respiratory Infections By Optimised Antibiotic Combination Dosage Regimens
Funder

Funding Amount
$697,731.00
Summary
Many bacterial ‘superbugs’ can increase their mutation rate, i.e. become hypermutable, and thus rapidly become resistant to multiple antibiotics. Chronic lung infections with hypermutable bacteria cause increased ill-health and death in patients and current treatments do not work well. We will develop improved treatments using combinations of available antibiotics. This project will provide guidance to doctors on how to treat infections more effectively and minimise emergence of resistance.
Glycosyltransferase Effectors Of Enteropathogenic E. Coli And Salmonella

Summary
This project aims to characterise the mechanisms of disease caused by bacterial pathogens including Salmonella and enteropathogenic E. coli. These pathogens cause a significant amount of diarrhoeal disease and mortality worldwide particularly in infants and in countries where water sanitation is poor. I aim to investigate the specific mechanisms the bacteria employ to manipulate and avoid our immune response during infection in order to better understand and combat diarrhoeal disease.
