Temporal analysis of prevalence and antibiotic-resistance patterns in Stenotrophomonas maltophilia clinical isolates in a 19-year retrospective study

This study investigates the isolation rates and resistance trends of Stenotrophomonas maltophilia infections over the past 19 years, revealing a significant increase in prevalence from 7% in 2004-2007 to 15% in 2020-2022. Most isolates were resistant to ceftazidime, levofloxacin, and trimethoprim-sulfamethoxazole. The prevalence is expected to reach 15.08% by 2030, highlighting the need for swift global action to address this growing issue.
