Nitrite produced by <i>Mycobacterium tuberculosis</i> in human macrophages in physiologic oxygen impacts bacterial ATP consumption and gene expression

Abstract excerpt

In high enough concentrations, such as produced by inducible nitric oxide synthase (iNOS), reactive nitrogen species (RNS) can kill Mycobacterium tuberculosis (Mtb). Lesional macrophages in macaques and humans with tuberculosis express iNOS, and mice need iNOS to avoid succumbing rapidly to tuberculosis. However, Mtb's own ability to produce RNS is rarely considered, perhaps because nitrate reduction to nitrite...
