Isolation and Characterization of Stenotrophomonas maltophilia Isolates from a Brazilian Hospital.

To characterize the antimicrobial resistance and virulence potential of this microorganism in a Brazilian hospital, a total of 936 samples were collected from a nosocomial environment and medical devices, and 100 isolates from clinical specimens were obtained in the same hospital.
