ABSTRACT=<p>Most pathogenic bacteria require iron for growth. However, this metal is not freely available in the mammalian host. Due to its poor solubility and propensity to catalyze the generation of reactive oxygen species, host iron is kept in solution bound to specialized iron binding proteins. Access to iron is an important factor in the outcome of bacterial infections; iron limitation frequently induces virulence and drives pathogenic interactions with host cells. Here, we review the response of <italic>Mycobacterium tuberculosis</italic> to changes in iron availability, the relevance of this response to TB pathogenesis, and its potential for the design of new therapeutic interventions.</p>
