description

Clonal variants of Mycobacterium tuberculosis (MTB) coexist in specific patients, although the dynamics of their emergence is unknown. We used MIRU-VNTR to detect microevolution leading to variants of MTB in 3 out of 19 patients (15%) soon after diagnosis (61-85 days). Most harbored SNPs and for some of them a potential functional role was suggested. Microevolution in tuberculosis seems to occur sooner and more often than expected and could affect tracking of transmission.
