Summary
The metabolism of vitamin B5 by pathogenic microorganisms has been recognised as an attractive target for developing drugs to combat various infectious diseases. The aim of the proposed work is to develop inhibitors of vitamin B5 metabolism in the bacterium that causes tuberculosis, using a powerful, multidisciplinary approach known as “fragment-based drug discovery”. This work is likely to yield potent inhibitors of the target bacterium, which could ultimately be used to treat tuberculosis.

Summary
Many disease-causing microbes subvert host cell defences to establish infection in part by transporting virulence proteins, termed “effector” proteins, into host cells via specialized protein secretion systems. We have discovered a new family of bacterial effectors that modify host proteins with a sugar and thereby inactivate them. Here we will characterise the function of these effector proteins during infection with E. coli and Salmonella.

Summary
This project aims to characterise the mechanisms of disease caused by bacterial pathogens including Salmonella and enteropathogenic E. coli. These pathogens cause a significant amount of diarrhoeal disease and mortality worldwide particularly in infants and in countries where water sanitation is poor. I aim to investigate the specific mechanisms the bacteria employ to manipulate and avoid our immune response during infection in order to better understand and combat diarrhoeal disease.

Using a novel approach, based on understanding how marine organisms specifically interfere with bacterial colonisation, the Team over the past seven years has identified a group of compounds that represent a novel group of antibiotics. Publications and patenting by the Team has demonstrated that the Team is at the forefront of research in this area. The novel antibiotics work by preventing bacteria sticking to surfaces and by preventing the bacteria from releasing toxins. The studies will concentrate on those bacteria that produce infections in the lungs (acute pneumonia), eyes (corneal infection), ear (middle ear disease), and abscesses.Read moreRead less
