The prevalence of colonization receiving mechanical ventilation in chronic care facilities has not been studied. The Multi-Drug-Resistant Organism (MDRO) Prevention Collaborative performed a point prevalence of patients receiving mechanical ventilation in all 18 chronic care facilities in Maryland between 7 March 2023 and 8 June 2023. Patients had at least one sputum, skin, or perianal surveillance culture collected (579 samples). Samples were tested using three microbiological methods: (i) growth on Acinetobacter CHROMagar, (ii) growth on MacConkey agar with an imipenem disk, and (iii) growth in brain-heart infusion broth with an imipenem disk, followed by growth on MacConkey agar. 21.4% (124\/579) of the samples collected grew\n                      <jats:italic toggle=\"yes\">S. maltophilia<\/jats:italic>\n                      .
