This website provides access to genomic data and genotypic definitions for isolates of the K. pneumoniae species complex (also called K. pneumoniae sensu lato, i.e., including K. pneumoniae, K. quasipneumoniae, K. variicola and related taxa) based on Multilocus Sequence Typing (MLST), core genome MLST (cgMLST), ribosomal MLST (rMLST), capsular typing (wzc and wzi sequencing) and MLST of virulence gene clusters. Please see references for more details. Note that this database is the primary source of data for the above genotypic and allelic definitions, as curated data are first imported here. Consequently, this database may be more up to date than external databases that download and provide our curated data on other platforms.
The nomenclature of beta-lactamases OKP, LEN and OXY and virulence schemes (Aerobactin, Colibactin, Yersiniabactin, Salmochinelin) are also curated and maintained within this database and can be accessed through the download page, section beta-lactamases, AbST, CbST, YbST and SmST.

The BIGSdb website is implementing new settings regarding data access. Data curated in 2025 (and later) will not be accessible for anonymous (non-logged-in users). If you wish to have access to data curated in 2025 and beyond, please register on the platform and login when using it. Note that access via the application programming interface (API) will also require authentication to access recent data (API authentication help link).

To ensure a smooth transition, anonymous data access will be periodically closed and opened from 1st October 2024 until the end of the year. For detailed planning, please follow this link.

On 1st January 2025, registration will be permanently mandatory to access data curated after the 31st of December 2024.

Please contact us if you have any questions.
