This website hosts three typing databases developed at the University of Oslo, Norway, for the Bacillus cereus group of bacteria, which includes B. cereus, B. anthracis, B. thuringiensis, B. mycoides, B. pseudomycoides, and B. weihenstephanensis. The databases contain MultiLocus Sequence Typing (MLST), MultiLocus Enzyme Electrophoresis (MLEE), and Amplified Fragment Length Polymorphism (AFLP) phylogenetic data.
LATEST NEWS (March 2012):
Integration of 84 additional isolates, including 7 with complete genomes and 2 novel isolates belonging to the B. cytotoxicus species.
LATEST NEWS (April-May 2010): Major upgrade of the database system. The databases have been updated with a number of new features including phylogenetic cluster classification, statistical support for branches on supertrees, lists of genotyping profiles, hyperbolic tree viewer, and more.
The server provides access to the newly developed comprehensive Multi-Datatype Database, HyperCAT, containing all strain information and phylogenetic typing data for the Bacillus cereus group, integrating MLST, MLEE, and AFLP data. The database provides multi-datatype strain comparisons including combined phylogenetic analyses based on supertree techniques, superclusters of strains sharing related genotypes, and more. HyperCAT is described in Tourasse et al. 2010 and Tourasse et al. 2010.

The server also provides access to the Multi-Scheme MLST Database, SuperCAT, containing the strain information and sequence data for all the five published MLST schemes for the Bacillus cereus group. The database allows to conduct multi-scheme strain comparisons including combined phylogenetic analyses based on supertree techniques, superclusters of strains sharing related genotypes, and more. SuperCAT is described in Tourasse and Kolstø 2008.

The server also gives access to the database specifically developed for the optimized Bacillus cereus group MLST scheme of Tourasse, Helgason et al. 2006.

Citing the database
If you use data from this website in publications, please cite this website, preferably as below:
"This publication made use of the University of Oslo's Bacillus cereus group MultiLocus and MultiData Typing website (http://mlstoslo.uio.no)"
The databases are constructed by using mlstdbNet software developed by Jolley et al, 2004, heavily modified by Dr. Nicolas J. Tourasse, and the PostgreSQL database management system. The website makes use of the facilities and support provided by the Norwegian EMBnet node and the HPC Supercomputing facilities at the University of Oslo.
The databases provided on this website are maintained by Dr. Nicolas J. Tourasse.
