Abstract:

Objective

To investigate the drug resistance and clinical distribution of Stenotrophomonas maltophilia collected from our hospital, and to guide rational clinical application of antibacterial.

Methods

Total of 163 stains of Stenotrophomonas maltophilia were collected from January 2014 to December 2014, the drug resistance rates and clinical distribution were analyzed by WHONET 5.6 software, retrospectively.

Results

The drug resistance rates of 163 stains of Stenotrophomonas maltophilia to ceftazidime, ticarcillin/clavulanic acid, levofloxacin and cotrimoxazole were 65.0% (106/163), 39.9% (65/163), 3.7% (6/163) and 1.2% (2/163). Among the 163 strains, 78.5% (128/163) were obtained from sputum, 16.0% (26/163) were obtained from blood; 41.7% (68/163) were collected from intensive care unit, and 21.5% (35/163) were collected from pediatric ward.

Conclusions

Stenotrophomonas maltophilia strains collected from our hospital mainly caused respiratory tract infection, followed by bloodstream infection. Infection caused by Stenotrophomonas maltophilia could be treated with levofloxacin or cotrimoxazole.
