Investigation of the effects of polymicrobial infection on the induction of otitis media

Funded Activity 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. 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.
