Study on of metallo-?-1actamases in pseudomonas aeruginosa / 重庆医科大学学报

ABSTRACT

Objective:To monitor the rug resistance and epidemiology state of pseudomonas aeruginosa(PA)isolated clinical pa- tient.Methods:antimicrobial sensitivity tests were performed by K-B method and metallo-?-lactamases-producing PA was genotyped by the randomly amplified polymorphic(PAPD)assay.Results:Among24 strains resistant to imipenem.19(8%)strains produced metal enzyme which could be distingurished into 10 kinds of PAPD type.the type ability was 100%.There was same gene type strain.Isolated from three patient and there were two kinds of gene types. Among 2 strains isolated from the same patient at the different time.Conclusions:the K-B method could be used to determine metal enzyme,rapidly and eonviently. And PAPD could to be used in the molecular epidemiological study of PA.
