Welcome to the Multi Locus Sequence Typing home page

MLST is a nucleotide sequence based approach for the unambiguous characterisation of isolates of bacteria and other organisms via the internet.

The aim of MLST is to provide a portable, accurate, and highly discriminating typing system that can be used for most bacteria and some other organisms. It is envisaged that this approach will be particularly helpful for the typing of bacterial pathogens.

To achieve this aim we have taken the proven concepts of multilocus enzyme electrophoresis (MLEE) and have adapted them so that alleles at each locus are defined directly, by nucleotide sequencing, rather than indirectly from the electrophoretic moblity of their gene products.

MLST was developed in the laboratories of Martin Maiden, Dominique Caugant, Ian Feavers, Mark Achtman and Brian Spratt.

This site is hosted at Imperial College with funding from the Wellcome Trust.
The location of the subsites for the individual species are shown on their respective front pages.
