Mechanisms Of Antibiotic-induced Persistent Bacterial Infection

Funding Amount
$632,048.00
Summary
Golden staph still causes significant human infections and resistance to antibiotics is an ever growing problem with this bacteria. This project will determine how resistance to some antibiotics is also changing the bacteria to promote persistent, difficult to treat infections. The insights from this study will help understand evolution of this bacteria, and help design new strategies for management.
Once treatable infections are becoming deadly because bacteria are developing broad antibiotic resistance. New medicines are urgently needed. Microbes themselves are the richest known source of new antibiotics but finding the 'good bugs' is like finding a needle in a microbial haystack. This project will use state-of-the art science to screen a previously overlooked source of rich microbial biodiversity and find new antibiotics.

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.
The Darwin Prospective Melioidosis Study: Years 27-31

Funding Amount
$1,281,718.00
Summary
The Darwin Prospective Melioidosis Study has documented 914 cases since 1989, with 115 fatalities. A surge in Darwin melioidosis cases over the past 5 years has been linked to urban development and the discovery of a new bacterial strain. Whole genome sequencing of our unique 25+ year set of bacteria and their linked patient data will unravel the changing epidemiology and identify important virulence factors, forming a foundation for future diagnostics, therapeutics, and vaccines.
Genomic Approaches To Understand And Control The Emergence Of Vancomycin Resistant Enterococcus Faecium (VREfm) In Australia.

Summary
VRE is a serious hospital superbug that has been increasing in many major hospitals around Australia, while at the same time MRSA (Golden Staph) infections have been decreasing. This project will find out why VRE is increasing by examining what happens to patients at a major Australian hospital from their time of admission to the onset of infection with VRE. At the end of the project we will have the first real understanding of how VRE is transmitted so we can develop effective infection control ....VRE is a serious hospital superbug that has been increasing in many major hospitals around Australia, while at the same time MRSA (Golden Staph) infections have been decreasing.

Bacterial Pathogenomics: Whole-genome Sequencing To Investigate Infection Transmission, Pathogenesis And Antibiotic Resistance

Funding Amount
$475,946.00
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.
Molecular Basis For The Emergence Of Community Acquired Staphylococcus Aureus

Funding Amount
$427,518.00
Summary
Golden Staph is a major problem in our hospitals but serious Golden Staph infections are increasingly common in the community, among otherwise healthy people who have had no contact with hospitals. This project will find out how Golden Staph is evolving to become more likely to cause disease in the community. This knowledge can then be used to design new strategies for early detection, prevention and treatment.

Summary
Uropathogenic Escherichia coli (UPEC) is 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 and spread worldwide. This project uses genomic and high-throughput functional analysis methods to understand E. coli ST131 virulence and resistance. The outcomes of the work will be a better understanding of how E. coli ST131 causes disease, and potentially new treatment regim ....Uropathogenic Escherichia coli (UPEC) is a major cause of urinary tract infections (UTI) and sepsis.

Summary
The Darwin Prospective Melioidosis Study has documented 761 cases since 1989, with 102 fatalities. This study has led to improved therapy and public health initiatives. New technology to sequence whole bacterial genomes provides an opportunity to determine why urban melioidosis is increasing and to analyse this unique 22+ year set of bacteria and their linked patient data to find the important bacterial virulence factors, forming a foundation for future diagnostics, therapeutics, 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.
