ABSTRACT
OBJECTIVE To study the existence of integron and metallo-?-lactamase in Stenotrophomonas maltophilia in our hospital.METHODS The antibiotic susceptibility was tested by K-B method.The genomic DNA and their plasmids were extracted.The integron and metallo-?-lactamase gene were amplified by polymerase chain reaction(PCR).RESULTS L1 and L2 genes were amplified in chromosomes and plasmids.Integrons Ⅰ and Ⅱ were detected in genomic DNA.CONCLUSIONS Existence of metallo-?-lactamase is one of reasons of multi-drug resistance in S.maltophilia.S.maltophilia can receive integrons and gain its multi-drug resistance from other strains.
