Differences between VNTR were mostly by a single repeat unit. However, a multiple-unit change also occurred. This suggests that a mechanism other than the slipped-strand mispairing might be responsible for the instability of VNTR in M. tuberculosis as well. This finding is useful for inferring phylogenetics of M. tuberculosis based on the VNTR genotypes. © 2007 Elsevier Ltd.
