Nontuberculous Mycobacterial Aggregation is Regulated by C:N Balance

Abstract

The current treatment regimen for nontuberculous mycobacteria (NTM) involves long courses of antibiotic cocktails that demonstrate limited efficacy and cause frequent and serious side effects. Mycobacterium abscessus, in particular, is difficult to treat, motivating studies to identify new therapeutic targets. Experiments using zebrafish and human cell culture lines have demonstrated that M. abscessus is more virulent when aggregated into cord-like biofilms, at least in part because of the decreased ability of phagocytes to efficiently engulf and kill corded M. abscessus cells.
