Streptococcus agalactiae (group B streptococcus, GBS) MLST Databases

The Streptococcus agalactiae MLST website contains two linked databases - one for allelic profiles and sequences, the other for isolate information. This structure offers advantages over a single database system. Further details can be found here.

Please note we are now using a new submission system - further details.

Please note that we will be upgrading the operating system on the primary database server on Thursday 22 November. Access to the databases will be maintained from a backup server, but offline jobs and access to the automated submission system will be disabled while the work is carried out.

This MLST scheme was developed by Nicola Jones (Nuffield Department of Clinical Laboratory Services, John Radcliffe Hospital, Oxford, UK) in the laboratory of Brian Spratt (now at the Department of Infectious Disease Epidemiology, Faculty of Medicine, Imperial College, London, UK) together with Derrick Crook (Nuffield Department of Clinical Laboratory Sciences, John Radcliffe Hospital, Oxford, UK) and Man-Suen Chan.

Database curated by Philippe Glaser and colleagues.
