Bacterial species identification is required in different disciplines and-depending on the purpose-levels of specificity or resolution of typing may vary. Nowadays, molecular methods are the mainstay for bacterial identification and sequence-based analyses are of ever-growing importance. For diagnostics, immediate results are needed and often real-time PCR of one or two loci is the method of choice while for epidemiological or evolutionary studies sequence data of several loci improve phylogenetic resolution to required levels. Multilocus sequence typing (MLST) and multilocus sequence analyses (MLSA) utilize sequences information of several housekeeping loci (eight for Borrelia) to distinguish between species. This method has been widely used for bacterial species and strain identification and will be described in this chapter.As more and more diversity is being detected in the Borrelia burgdorferi sensu lato species complex, the importance of accurate species and strain typing has come to the fore. This is particularly significant with a view of differentiating human pathogenic and non-pathogenic strains or species and understanding the epidemiology, ecology, population structure, and evolution of species.
