Biological variability and the emergence of multidrug-resistant tuberculosis
Abstract
A new study demonstrates that bacterial mutation rates associated with the Mycobacterium tuberculosis lineage most commonly linked to multidrug-resistant tuberculosis are multifold higher than shown in previous studies. This discovery, when considered together with recent findings on pharmacokinetic variability in patients, leads to new models of how multidrug-resistant tuberculosis arises, with direct therapeutic implications.
