Hosts multi-locus sequence typing (MLST) data. PubMLST resources are hosted using the Bacterial Isolate Genome Sequence Database (BIGSdb) platform. A RESTful application programming interface (API) makes the curated and structured data on PubMLST accessible for programmatic access. Users may need to authenticate themselves, for instance to submit data for curation. Access to specific data resources can also be limited to registered users or project members.
