MLST databases contain the reference allele sequences and sequence types for each organism, and also isolate epidemiological data. The websites contain interrogation and analysis software which allow users to query their allele sequences and sequence types.  MLST is widely used as a tool for researchers and public healthcare workers.
The majority of MLST databases are hosted at web server currently located in Oxford University ([http://www.pubmlst.org pubmlst.org]).
The database hosted at the site hold the organism specific reference allele sequences and lists of STs for individual organisms.
To assist the gathering and formatting of the utilized sequences a simple and free plug-in for Firefox has been developed ([http://science.agrool.gr/mtrantas/?p=168 link] ).
