A novel approach to automated genotyping of Mycobacterium tuberculosis using a panel of 15 MIRU VNTRs.

In this study, we present a new approach to variable number tandem repeats (VNTR) analysis using the QIAxcel capillary electrophoresis system and a software-integrated peak calling function. Allelic ladders representing 15 mycobacterial interspersed repetitive units (MIRU)-VNTR loci were used to define peak calling tables thereby enabling high precision Mycobacterium tuberculosis strain identification.
