Multilocus sequence typing
Multilocus sequence typing (MLST) is a technique in molecular biology for the typing of multiple loci, using DNA sequences of internal fragments of multiple housekeeping genes to characterize isolates of different species. It is most commonly applied to microbes, mostly prokaryotes and yeasts, as they tend to be hard to differentiate using other means.
