Escherichia coli MLST Database


Please note that three distinct MLST schemes (using distinct sets of genes) exist for E. coli: Institut Pasteur's MLST scheme (this site), Mark Achtman's MLST scheme ( and T. Whittam's MLST scheme ( A comparaison study is ongoing to establish correspondence between the two former MLST schemes.

The Escherichia coli 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.
