The current "gold standard" in molecular epidemiological studies of Mycobacterium tuberculosis is IS6110 RFLP based on the IS6110 polymorphism. Recently, PCR-based methods are becoming increasingly important. Newly, fast ligation-mediated PCR (FLiP), based on the IS6110 polymorphism, was proposed. In this study, the discriminatory power of FLiP, spoligotyping and MIRU-VNTR typing, in differentiation of M. tuberculosis isolates was compared. The discriminatory index (HGI) of spoligotyping, MIRU-VNTR analysis, and FLiP was 0.653, 0.837, and 0.917, respectively. This indicates that FLiP allows a high level of differentiation among M. tuberculosis strains and it might be a valuable alternative for the other typing methods.
