Antibacterial potential of Stenotrophomonas maltophilia complex cystic fibrosis isolates.

complex (Smc) in external environments, for the elimination of commensal species and colonization of upper respiratory tracts to enable early infections, and for competition against other pathogens after establishing chronic infections. These intermicrobial interactions could facilitate the acquisition of Smc by people with cystic fibrosis from environmental or nosocomial sources. Elucidating the mechanisms used by Smc to eliminate other bacteria could lead to new insights into the development of novel treatments.
