Summary
Lung infections are a major disease burden worldwide. Indigenous Australians are affected more; adults with severe lung disease can die in their 30s and 40s. These diseases start early, yet no in-depth studies of bacteria causing lung infections in children have been done. Our expert team proposes to use existing lung fluids from nearly 500 children with chronic lung disease (58% Indigenous), and state-of-the-art laboratory methods, to inform the design of vaccines to prevent lung disease.
Tuberculosis is one of the most threatening infectious diseases worldwide due to the low efficiency of the only licensed anti-tuberculosis vaccine, BCG. This project aims to interrogate two previously neglected immune mechanisms and their potential to enhance vaccine-induced immunity by incorporating these mechanisms into new genetically modified BCG strains. We will also investigate alternative BCG vaccination routes to generate long-lived immune cells that can rapidly control the infection.
Group A streptococcus (GAS) is a bacteria that causes a wide range of disease in humans. GAS diseases are more common in Australias Indigenous population, and other health and economically disadvantaged groups than more affluent groups. In this study we will evaluate the effectiveness of novel vaccine candidates designed to prevent infection from all strains of GAS.
Uropathogenic Escherichia coli (UPEC) are 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 worldwide. This project addresses the mechanisms by which E. coli ST131 can colonise the urinary tract and cause disease. The outcomes of this project will be a better understanding of how E. coli ST131 causes disease, and potentially new treatment regimes for UTI.
