description <i>Pseudomonas aeruginosa</i> and <i>Mycobacterium abscessus</i> are opportunistic pathogens that cause severe infections in hospitals, and their co-infections are increasingly reported. The interspecies interactions between these two bacterial species and their potential impacts on infections are largely unexplored. In this study, we first demonstrated that <i>P. aeruginosa</i> inhibits the growth of <i>M. abscessus</i> by iron chelating via <i>pqs</i> quorum sensing. Next, through proteomic analysis, we discovered that the PQS molecule significantly changed a large amount of protein expression in <i>M. abscessus</i>, including proteins involved in the type VII secretion system and iron homeostasis. Furthermore, we revealed that PQS significantly enhanced the production of bacterial membrane vesicles (MVs) by <i>M. abscessus</i>. Our study suggests that the <i>P. aeruginosa</i> PQS can serve as an interspecies signaling molecule to communicate with <i>Mycobacterium</i> and affect their physiology and virulence.
