Summary
In hospitals and in nature, diverse microbes, such as bacteria and fungi, often live in close proximity to each other. Their interactions can either be helpful or detrimental to one another, and such interactions are likely important for their ability to cause human disease. This proposal aims to study the mechanisms by which bacteria interact with fungi and by doing so, will identify important mechanisms of how microbes cause human illness and also uncover new targets for antibiotic development ....In hospitals and in nature, diverse microbes, such as bacteria and fungi, often live in close proximity to each other.

Summary
Middle ear infection is a highly prevalent paediatric disease characterised by an inflammation of the middle ear and is the most prevalent illness of childhood. It is reported that greater than 80% of children have had at least one episode of acute otitis media by 3 years of age and almost 40% of children have more than 6 episodes by age 7 years. The cause and pathogenesis of middle ear infection are multifactorial and influence of prevalence and chonicity of the infections.

It is reported that greater than 80% of children have had at least one episode of acute otitis media by 3 years of age and almost 40% of children have more than 6 episodes by age 7 years. The cause and pathogenesis of middle ear infection are multifactorial and influence of prevalence and chonicity of the infections. Prevention of bacterial middle ear infection caused by Streptococcus pneumoniae, nontypeable Haemophilus influenzae and Moraxella catarrhalis requires a much better knowledge of how these bacteria interact with each other and with the host. The poor efficacy of the current pneumococcal paediatric vaccine for preventing middle ear infections highlights this deficiency in our knowledge and will impede the development of a suitable multvalent vaccine to prevent infection by the 3 major bacterial pathogens. This study will investigate how the bacteria colonising the respiratory tract interact during infection and how they affect the host.Read moreRead less

Summary
Cystic fibrosis (CF) is the most common autosomal recessive disorder in humans, affecting 1:2000 people. Mortality is often caused by Pseudomonas aeruginosa lung infections which have recently been shown to occur not only environmentally but also via person-person contact, usually during CF clinic visits. This project will elucidate the molecular traits responsible for these 'epidemic' P. aeruginosa infections, with the aim of finding novel therapeutics and infection control strategies.
