Multi-Scheme B. cereus group MLST Database, SuperCAT

LATEST NEWS (July 2020):
   MAJOR UPDATE OF THE DATABASE: ~900 additional isolates, including 239 with complete genomes.
   MLST sequences and information from 19 brazilian B. cereus and B. thuringiensis isolates kindly provided by Dr. Adriana M. Vivoni, Oswaldo Cruz Institute (IOC-FIOCRUZ), Rio de Janeiro, Brazil.
   MLST sequences and information from the chinese rice isolate B. cereus 192 kindly submitted by Dr. Yang Yong, Zhejiang Provincial Center for Disease Control and Prevention (Zhejiang CDC), Hangzhou, Zhejiang, China.
   Now including data from four recently defined species that may be novel members of the B. cereus group: B. toyonensis (Jimenez et al. 2013), B. gaemokensis (Jung et al. 2010), B. manliponensis (Jung et al. 2011), and B. bingmayongensis (Liu et al. 2014).

SuperCAT Info

   This database provides information and sequence data for all isolates that have been typed using any of the 5 published MLST schemes for the Bacillus cereus group, as well as strains whose complete genomes have been sequenced (currently 2458). The database is described in Tourasse and Kolstø 2008. The current dataset contains a total of 5106 isolates and 26 gene fragments from 25 genes, as of August 7, 2020. Visit the MLST Schemes and Scheme Overlap pages for detailed information about the various schemes and their overlap in terms of genes and isolates. The Strain Statistics page gives overall statistics about species distribution and strain origin.
   Conflicting isolates: Note that an additional set of 0 isolates, including 0 of the complete genomes, have not been included in the main database because they exhibit conflicting phylogenetic positions among MLST schemes or exhibit conflicting typing data from different collections or databases. These conflicting isolates are listed here.

   The isolates have been classified according to the seven major phylogenetic clusters of the B. cereus group population defined by Guinebretiere et al. 2008 (denoted I-VII). In order to provide a classification that is consistent across typing methods, isolates have been assigned to a particular cluster if they belong to that cluster in MLST-only, MLST+AFLP, and MLST+AFLP+MLEE phylogenetic analyses. Otherwise, isolates that could not be assigned consistently to a given cluster or that do not belong to any of the seven major clusters are classified as "unclustered". The branches of every phylogenetic tree provided or generated by the database are color-coded according to cluster. An additional tool for affiliating isolates to the seven clusters based on the panC gene sequence is provided by Guinebretiere et al. at this URL (see Guinebretiere et al. 2010).

   The species assignments listed in the database correspond to the original assignments reported in publications, bacterial culture collections, and sequence databases. Some isolates may have to be reclassified upon further phylogenetic, genetic, and/or microbiological studies.

Note: The MLST data of SuperCAT have been combined with AFLP and MLEE typing data in the HyperCAT database, also available on this server, which provides a comprehensive multi-datatype phylogenetic view of the B. cereus group population.

   The SuperCAT MLST database provides tools for comparing strains based on data from the 5 MLST schemes and provides:
