Summary
Golden Staph is a major problem in Australian hospitals. This project will use cutting edge technology to investigate how Golden Staph responds to and resists antibiotics used to treat human infections, leading to new strategies for the prevention and treatment of antibiotic resistant bacteria.
Role Of IS26 In Antibiotic Resistance Gene Recruitment, Dissemination And Expression

Summary
Antibiotic resistance is increasing, compromising the efficacy of front-line antibiotics. Untreatable infections due to bacteria that are resistant to all available antibiotics are being seen more often. To control the spread of resistance, an understanding of how resistance arises and is spread among bacteria is needed. This requires information about how the genetic elements that mobilize them work. This project will study one of the most important of these elements.
Targeting Nucleic Acid Synthesis And Cell Division In Gram-negative Bacterial Pathogens

Summary
Some bacteria like Acinetobacter species cause infections in hospitals that are difficult to treat because they have acquired resistance to most antibiotics. This project will combine the complementary expertise of five research groups to develop knowledge of, and how to block, three essential processes in these worrying pathogenic species: copying of DNA, RNA synthesis, and cell division. This promises to lead to development of new antibacterial therapies.
Exploitation Of Bacterial Transcription Initiation As A Target For New Antimicrobials

Summary
Antibiotic resistant infections from 'superbugs' are a major health problem. We will exploit information we have gathered on the machinery that copies genetic information into a message to discover chemical compounds that can be used for the development of new antibiotics with a novel mechanism of action.
Non-coding RNA Regulation Of Virulence In Enterohaemorrhagic E. Coli

Summary
Shiga toxins cause potentially fatal haemolytic uremic syndrome (HUS) and are transferred between bacterial pathogens by bacteriophage (bacterial viruses). We have recently found that the Shiga toxin encoding bacteriophage encodes an unusually large number of non-coding RNAs (RNA regulators of gene expression). This Project aims to understand how these RNA regulators benefit the Shiga toxin bacteriophage and use this knowledge to develop interventions that will prevent expression of the toxin.
