Mycobacterium bovis frd operon phase variation hijacks succinate signaling to drive immunometabolic rewiring and pathogenicity

Abstract excerpt

Tuberculosis (TB), caused by Mycobacterium tuberculosis complex (MTBC) pathogens, remains a global health threat. While bacterial genetic adaptations during host infection are poorly understood, phase variation in genomic homopolymeric tracts (HT) may drive pathogenicity evolution. Here, we demonstrate that M. bovis exploits HT insertion mutations in the fumarate reductase-encoding frd operon to subvert host...
