%X Background: <i>Stenotrophomonas
maltophilia</i> is a multidrug-resistant, Gram negative <i>bacillus</i> that has emerged as an opportunistic pathogen associated
with high morbidity and mortality rates. Aim: The aim of this study is to
describe the characteristics of patients with bloodstream infections due to <i>S. maltophilia</i>. Methods: A descriptive
retrospective study was performed at the ICUs over seven-year period in a teaching
hospital. Cases of SMB were identified through a review of clinical
microbiology laboratory and patient¡¯s records were retrieved for analysis. Findings:
There were 22 deaths (71%) 15 ¡À 12 days after the bactaeremia. In our study,
more than half of patients (17/31) was exposed to broad-spectrum antibiotic
specifically imipinem (IMP) before their positive culture. Antibiotic
susceptibility testing revealed that isolates were most sensitive to ciprofloxacin
(84%) and to trimethoprim-sulfamethoxazole (71%). A probable portal of entry
was identified in 27.3% of cases and 57% were catheter-related. Conclusion:<i> </i>Our results were similar to those
described by other authors reported in the literature in the last 20 years.
Prevention of <i>S. maltophilia</i> acquisition and infection depends on higher emphasis on control of antimicrobial
consumption and consideration of environmental reservoirs.
