Drug sensitive test and three-dimensional test220 strains of Pa were isolated from hospitalized patients between 2003 and 2007. K-B method was used to tested the susceptibility of 10 different antibiotics. IRPa was screened by testing the minimal inhibitory concentration of imipemem by using agar diluiion method.The susceptibility of these IRPa to the antibiotics was analysised. Three-dimensional test was used to identify the different kinds of beta lactamases from 220 strains of Pa.2.Carbarpenems hydrolytic enzyme genes and oprD2 gene were detectedamong the selected IRPa strains, PCR method was performed to detect carbapenemase genes which included GES、KPC、SPM、VIM、IMP、GIM gene and the oprD2 gene;Multiplex PCR were used to detect OXA genes and plasmid-mediated AmpC beta lactamase genes; The expression of the chromosomal AmpC beta lactamases and oprD2 genes in IRPa strains were analyzed by Real-time PCR.3.Identification and characterization of integronsIntegrase gene was detected by PCR, and the classification of integrons was performed by using restriction fragment length polymorphism.PCR was performed to detect the qacE△1-sull gene,and the gene cassetes which are located at variable region of integrons in the strains were detected to be positive.
