Summary
Epidemic invasive GAS disease is associated with the emergence of the globally disseminated M1T1 clone and is linked to the mutation in the CovR/S regulator. This mutation leads to over- expression of SpyCEP and inhibits recruitment of neutrophils to the site of infection. Inclusion of an immunogenic fragment of SpyCEP into our current vaccine would enhance its efficacy and lead to the development of a vaccine with a wider coverage and better protective efficacy against hypervirulent GAS strains
Systematic Investigation Of Conceivable Mechanisms That Could Lead To False Positive Diagnoses Of Sexually Transmitted Infections In Young Children.

Summary
Diagnosis of a sexually transmitted infection (STI) in a young child has serious social and legal consequences, because it is usually regarded as indicative of sexual abuse. It is therefore critical to understand the probability of such a diagnosis in the absence of sexual abuse. We will investigate false positives that arise by contamination of the urogenital site by STI agents that also infect the eye, and the transfer of contaminants from fingers to diagnostic specimens.

Summary
Chlamydia are major causes of sexually transmitted disease but they also cause respiratory disease (Chlamydia pneumoniae) which is widespread across Australia and indeed the whole world (80% of people have been infected at some time in their life). Recent results suggest that the respiratory infections in humans came from animals and in this project we aim to identify which animals might have transmitted this infection to humans and determine if there is a continuing risk. We also plan to determ ....Chlamydia are major causes of sexually transmitted disease but they also cause respiratory disease (Chlamydia pneumoniae) which is widespread across Australia and indeed the whole world (80% of people have been infected at some time in their life). Recent results suggest that the respiratory infections in humans came from animals and in this project we aim to identify which animals might have transmitted this infection to humans and determine if there is a continuing risk. We also plan to determine what defines animal versus human infections.Read moreRead less
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.
