Abstract:
OBJECTIVE To investigate the distribution and characterization of the classes Ⅰ,Ⅱ and Ⅲ integrons on Stenotrophomonas maltophilia and clarify their influence on the bacterial drug-resistance.METHODS A multi-PCR assay using specific primers of int1,int2 and int3 was constructed to screen classes Ⅰ,Ⅱ and Ⅲ integrons.RESULTS Class Ⅰ integron was detected in 13.4% of clinical isolates,3 isolates harbored among class Ⅱ integrons. There was not been reported in abroad.CONCLUSIONS Classes Ⅰ and Ⅱ integrons could play an important role in causing the antibiotic multidrug resistance.
