Distribution and Drug-resistance of Stenotrophomonas maltophilia / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To get knowledge of the distribution and drug-resistance of Stenotrophomonas maltophilia in our hospital and improve the level of diagnosis and treatment.METHODS The automatic drug sensitive test and the paper spreads medicine sensitive test were carried on to 162 strains of S.(maltophilia) with the index of the VITEK system.RESULTS In all clinical samples,S. maltophilia isolated from phlegm was the most(90%),then was from secretion and swab.The majority of 162 strains were multidrug resistant.But to the(trimethoprim)-sulfamethoxazole and ciprofloxacin,the drug resistance was low((20.4%) and 22.2%,respectively).CONCLUSIONS S.maltophilia is the prevalent pathogen of nosocomial infection in ICU.And most of it are(isolated) from phlegm.So use antibiotics correctly,(reduce) invasive examinations or treatments and strengthen drug-resistant monitoring,are helpful to prevent and control S.maltophilia nosocomial infection.
