Summary
Melioidosis is an emerging disease in Australia and South-East Asia due to its association with diabetes and changing climate. The current clinical methods often fail to save the life of melioidosis patients who develop sepsis. This study will search for melioidosis metabolite biomarkers that help in rapid diagnosis and in selecting adequate treatment which is essential to reduce the mortality. Future, similar studies on other sepsis infections could improve clinical sepsis management world wide ....Melioidosis is an emerging disease in Australia and South-East Asia due to its association with diabetes and changing climate.

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.

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.
Nasal Epithelium As A Portal Of Entry For Burkholderia Pseudomallei, With Special Reference To Neurological Melioidosis

Summary
Melioidosis is a potentially fatal disease of manly tropical Australia and SE Asia and an emerging disease worldwide. It disproportionately affects indigenous Australians. It is caused by a bacterium found in soil and water and infection may be by inhalation in the rainy season. One manifestation of melioidosis is neurological symptoms. This project seeks to establish sites and pathways of infection resulting from inhalation, including the pathway from nasal mucosa to brain.

Summary
Melioidosis is an often fatal disease of mainly tropical Australia and SE Asia caused by a bacterium which is found in soil and water. Infection occurs via wounds or by inhalation. Melioidosis has recently become endemic in south-west Western Australia and south-eastern Queensland, and could represent an emerging disease worldwide.

Infection occurs via wounds or by inhalation. Melioidosis has recently become endemic in south-west Western Australia and south-eastern Queensland, and could represent an emerging disease worldwide. Melioidosis disproportionately affects Aboriginal Australians. Melioidosis has many forms including septicemia with damage to most organs, particularly lung, spleen and liver, acute localised suppurative infection and pneumonia. Melioidosis may also become latent, and later develop into an acute and fatal infection. It is important to understand, at the molecular level, how and why the causative bacterium is able to cause disease. Only with such an understanding can measures be undertaken to prevent the disease, or novel methods developed to control the disease. Colonisation of a host is a first step in the disease process for all bacteria which cause disease. Large protein molecules located on the surface of disease-causing bacteria are usually neccessary for colonisation of the host since they allow adherence to the surface of host cells. We have previously undertaken a basic study of adherence. This study will build on this research with the aim of identifying molecules which mediate adherence to host cells, using in vivo and in vitro methods, including the techniques of molecular biology. This study will inevitably lead to the development of vaccine candidates which is important to the management of melioidosis, particularly in high risk groups. It may also allow the development of novel antimicrobial compounds.Read moreRead less
