Summary
Moraxella catarrhalis (Mcat) and non-typeable Haemophilus influenzae (NTHI) are two major causes of middle ear infections in children, and respiratory disease in adults. This project aims to characterise novel regulatory mechanisms associated with disease isolates of these bacteria. This research will aid vaccine development by defining the repertoire of stably expressed potential vaccine targets of Mcat and NTHi, and will improve our understanding of host-pathogen interactions.

Summary
The bacterium Haemophilus influenzae is a leading cause of ear infections. Hearing loss from these infections can seriously affect literacy and educational performance. As no vaccine is available, we will research how the bacterium makes the HMW protein that is important in infection. We will study how sugars are added to the surface of this protein so that the bacterium can escape the immune system, its role in related bacteria and how it may be used in a vaccine.
