    ### Response:
    Stenotrophomonas maltophilia (S. maltophilia) infection is a healthcare-associated bacterial infection caused by S. maltophilia bacteria. These bacteria typically colonize (live in or on) areas of the body without causing infection. However, people who are hospitalized and receiving treatment for other conditions may be susceptible to infection, especially those with severely impaired immune systems.
