Klebsiella pneumoniae species complex

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.

⚠ Maintenance: A BIGSdb-Pasteur maintenance is ongoing until Saturday, July 05th. All services are offline until late in the evening (Central European Time). During this period, the server and API are unavailable. Please note that job submission is not available and all unfinished jobs have been killed. Sorry for any inconvenience. If any questions, contact us

Data access policy note: since January 1st, 2025, registration and authentication are mandatory to access all data curated after this date, either via the web interface or via the application programming interface (API authentication help link). Please contact us if you have any questions.

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.
