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.

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 Odile Harrison.
