show Abstracthide AbstractThis project will allow the establishment of a solid baseline population structure of major and minor sequence clusters (as a proxy for speciation) within the Viridans streptococci and, in combination with existing sequence datasets from the pneumococcus, will form a solid basis for initial ‘speciation’ and fine scale clustering within lineages. Data will be provided through cGPS within a web application (www.wgsa.net) allowing the interrogation of metadata in a genomic context and forming a solid resource for the public health community
