title: TB or Not TB: how Mycobacterium tuberculosis may evade drug treatment.
abstract: In this issue of Cell, a study by Valerie Mizrahi and her colleagues suggests that a putative error-prone DNA polymerase encoded by the dnaE2 gene of Mycobacterium tuberculosis may bypass certain types of DNA base damage, generating mutations. This may be an important mechanism for generating drug-resistant strains of M. tuberculosis.
