This page provides access to Multilocus Sequence Typing (MLST) data for Escherichia coli isolates, using the MLST scheme developed at Institut Pasteur. Please see references for more details. For a correspondence of Pasteur's scheme sequence types (ST) with STs of other schemes, please refer to Clermont et al. 2015.

ISO9001-logo
ISO 9001: We are pleased to announce that the BIGSdb-Pasteur platform has obtained ISO9001 certification in March 2026, and has been included in the scope of the CRBIP ISO 9001:2015 certification.
Alleles & profiles database
The typing database contains nomenclature - allele definitions that provide an identifier for every unique allele sequence, and MLST profiles that index each unique combination of alleles with a sequence type (ST).
Isolates & genomes database
The isolate database consists of isolate records containing provenance and phenotype information linked to molecular typing information. These records may also include genome assemblies.
