Identification of genes required for <i>Mycobacterium abscessus</i> growth in vivo with a prominent role of the ESX-4 locus

Significance The coevolution of mycobacteria and amoebae seems to have contributed to shaping the virulence of nontuberculous mycobacteria in macrophages. We identified a pool of genes essential for the intracellular survival of Mycobacterium abscessus inside amoebae and macrophages and discovered a hot spot of transposon insertions within the orthologous ESX-4 T7SS locus. We generated a mutant with the deletion of a structural key ESX component, EccB 4 . We demonstrate rupture of the phagosomal membrane only in the presence of an intact eccB 4 gene. These results suggest an unanticipated role of ESX-4 T7SS in governing the intracellular behavior of a mycobacterium. Because M. abscessus lacks ESX-1, it is tempting to speculate that ESX-4 operates as a surrogate for ESX-1 in M. tuberculosis .
