Abstract
Treatment of Stenotrophomonas maltophilia infections comprises of sulfamethoxazole/tripethoprim (SXT) or fluoroquinolones. We investigated antimicrobial resistance, presence of resistance genes (sul1, smqnr) and clonal dissemination in S. maltophilia from a university hospital. Among 62 isolates, 45 (73%) represented infection. Two isolates (3%) were resistant to SXT and three (5%) to levofloxacin. Twenty-nine isolates (47%), including two out of three levofloxacin-resistant, carried smqnr. Resistance of S. maltophilia was low and was not associated with sul1 or smqnr carriage. Although high degree of genetic diversity was identified (29 pulsotypes), 22/62 (35.5%) strains were classified into four clones; clone b was associated with bacteraemias.
