Summary
Streptococcus pyogenes (group A Streptococcus; GAS) causes life-threatening invasive infections including flesh-eating disease and toxic shock syndrome (>600,000 cases and 163,000 deaths per year). We recently discovered the trigger for invasive disease in a globally disseminated GAS strain. The aim of this work is to determine whether this trigger applies to other strains associated with GAS invasive disease. These studies will allow the development of new therapeutics and treatments.
Understanding, Reducing And Preventing Communicable Diseases Using Applied Pathogen Genomics

Funding Amount
$303,014.00
Summary
Infectious diseases are a major threat to human health. New molecular methods, particularly whole genome sequencing, promise a revolution in the way in which infections are diagnosed, detected and tracked in the 21st century. This research will use cutting edge molecular technologies to understand the factors that lead to the emergence, evolution and spread of important bacteria, including bacteria that are resistant to antibiotics.
Investigating The Role Of MtrA In Antimicrobial Resistance Of N. Gonorrhoeae

Summary
The main aim of this project is to investigate how genes are regulated by a specific protein called MtrA. This protein has been involved in antibiotic resistance in Neisseria gonorrhoeae, and has recently been shown to be important for the survival of N. gonorrhoeae in early infections. Understanding the exact mechanisms of this resistance, and how the genes regulated by MtrA are important for early N. gonorrhoeae infections would aid in treatment options.
Human Genetic Susceptibility To Bacterial Invasion And The Interaction With Chronic Helminth Infections

Funding Amount
$377,040.00
Summary
A genetic study will be undertaken to identify genes that increase an individual’s risk of developing a bloodstream bacterial invasion following severe pneumonia, a leading cause of infant death world-wide. The risk of getting a bacterial infection is increased in individuals already infected with parasitic intestinal worms. This may also reduce drug and vaccine efficacy. Research will be undertaken to investigate these relationships for future drug and vaccination development.
Using Genetic Tools To Study Helicobacter Pylori Pathogenesis And Persistence

Funding Amount
$316,449.00
Summary
H. pylori infection is the leading cause of gastric ulcer disease and stomach cancer. In light of emerging antibiotic resistance and failed vaccine trials, alternative therapies are needed to treat this lifelong infection. This project aims to develop tools to identify and characterize genes required by H. pylori for infection which will serve as new drug targets. This new knowledge will also contribute to a better understanding of the persistence of this and other bacteria.
Behavioural And Microbial Risk Factors Associated With Bacterial Vaginosis In Young Women

Funding Amount

Summary
Bacterial vaginosis (BV) is one of the commonest genital infections in women of reproductive age. Few data have determined the incidence of BV among young low risk women and the associated risk factors. This study aims to establish the incidence of BV in a cohort of young women and determine if BV is sexually transmitted. We hope this research will led to improvements in management and treatment of BV.
