Risk factors and clinical characteristics for Stenotrophomonas maltophilia infection in an acute care hospital in Japan: a single-center retrospective study

In actual clinical practice, S. maltophilia was more frequently isolated from sputum. However, most of the cases were colonization, and cases of infection were rare. Early treatment initiation should be considered for S. maltophilia infection in cases where the pathogen is detected from sterile sites, such as blood cultures and pleural fluid or from sputum in cases with a high SOFA score and CV catheter insertion.
