Brief description Streptococcus agalactiae, more commonly referred to as group B streptococcus (GBS), is the commonest cause of life-threatening infection (specifically bacteraemia, pneumonia and meningitis) in neonates. Mortality is high even in developed countries where antimicrobial therapy is readily available. In spite of the importance of GBS disease, the precise molecular mechanisms whereby the organism colonizes, invades and damages host tissues are poorly understood. The long term goal of this project is to gain a complete understanding of the pathogenesis of GBS disease and to apply this to development of improved preventative strategies. We propose to carry out a comprehensive molecular characterization of genes encoding putative GBS virulence determinants, with particular reference to those which encode the capacity to adhere to and invade host cells. GBS carrying defined mutations in these genes will be constructed and their virulence will be compared with that of the otherwise isogenic parental GBS. This will enable us to determine the precise contribution of each putative virulence factor to the pathogenesis of disease. Moreover, proteins shown to be important in this process will be tested for vaccine potential.
