Abstract:
OBJECTIVE To investigate the drug-resistant genes associated ?-lactams in Pseudomonas aeruginosa(isolated) in Shaoxing,Zhejiang Province.METHODS Thirty nine strains of P.aeruginosa were isolated from(hospitalized) patients,and drug-resistant genes were detected by PCR.RESULTS The positive rates of genes of TEM, CARB,VIM and DHA were 2.6%,30.8%,23%,and 7.7%,respectively,oprD2 gene was all lack.Genes of SHV,OXA-1 groups,OXA-10 groups,PER,VEB,GES,IMP,SPM and GIM were not found in all 39 isolates tested.CONCLUSIONS There are very high positive percentages of CARB and VIM genes in P.aeruginosa(isolated) clinically.The oprD2 gene lack is the important mechanism of P.aeruginosa resistant to(imipenem.) The CARB genes in P.aeruginosa are firsted report domestically.
