Summary
Helicobacter pylori is a highly persistent pathogen and remains a significant problem worldwide, causing gastritis, peptic ulcer disease and gastric cancer. This project will increase our understanding of how H. pylori infection persists for the life of its human host and will provide knowledge that is critical in developing new strategies for preventing these infections.
Interrogation Of Streptococcal Genomic Epidemiology Within Disease Endemic Regions

Funding Amount
$325,896.00
Summary
Group A streptococcal (GAS) bacterial infections within the Indigenous populations of Northern Australia are amongst the highest in the world. This project uses comparative bacterial genomics to examine current and historical outbreaks of GAS disease in Northern Australia relative to globally sourced GAS. This will be used to examine the spread of disease causing GAS between remote communities as well as investigating genetic markers of disease and informing therapeutic interventions.
How Are Klebsiella Pneumoniae Infections Acquired In Hospital?

Summary
Klebsiella pneumoniae (Kp) bacteria are among the top causes of hospital infections and are often resistant to a wide range of antibiotics. While some hospital bugs are well-studied, we are considerably behind in our understanding of Kp, which can be carried in our bodies as a commensal without causing disease. Bacterial genomics will be used to dissect how Kp infections are acquired in hospital, including investigating the evidence for hospital transmission and the role of commensal carriage in ....Klebsiella pneumoniae (Kp) bacteria are among the top causes of hospital infections and are often resistant to a wide range of antibiotics.

Identifying Key Players In The Spread Of Antimicrobial Resistance

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.

Phase Variable Protein Glycosylation In Bacteria Mucosal Pathogens And Its Role In Immune Evasion

Summary
The bacterium Haemophilus influenzae is a leading cause of ear infections. Hearing loss from these infections can seriously affect literacy and educational performance. As no vaccine is available, we will research how the bacterium makes the HMW protein that is important in infection. We will study how sugars are added to the surface of this protein so that the bacterium can escape the immune system, its role in related bacteria and how it may be used in a vaccine.
