ABSTRACT
OBJECTIVE To investigate genes associated with the drug-resistance of ?-lactam antibiotics in Pseudomonas aeruginosa(PAE) isolated from clinical patients. METHODS ?-Lactamase genes including TEM,SHV,OXA-10,PER,VEB,GES,CARB,IMP,VIM,SPM,GIM,DHA,FOX,MOX and oprD2 were detected by PCR amplification in 33 PAE isolates. RESULTS TEM,SHV,GES,CARB and VIM genes were positive in 100%,6.1%,6.1%,9.1% and 12.1% of 33 isolates,respectively.The deletion of oprD2 gene was found in 22 isolates.Other ?-lactamase genes were absent in all isolates.By PCR amplification,DNA sequencing and BLASTn comparison analysis,the CARB genes of 2 strains were demonstrated to be CARB-3 and the VIM genes of 2 strains were VIM-2. CONCLUSIONS P.aeruginosa carries various beta-lactamase genes in clinical PAE patients,and the deletion ratio of oprD2 gene is high.
