多重PCR在多重耐藥鮑曼不動桿菌耐藥基因檢測中的應(yīng)用
[Abstract]:Objective to establish a multiplex PCR reaction system for simultaneous detection of multidrug resistant genes of Acinetobacter baumannii (Multidrug-Resistant Acinetobacter Baumannii,MDRAB) and to understand the distribution of MDRAB resistance genes in order to provide molecular biological basis for clinical treatment and infection control of MDRAB. Methods four pairs of primers were designed for blaoxa-23,bla Ade-B,blaint-1 and bla ISCR-1 of four resistant genes of MDRAB, and the reaction conditions were designed to detect the four resistant genes simultaneously in the same PCR reaction system. The multiplex PCR reaction system was used to detect the drug resistance genes carried by clinical isolates of MDRAB. Results in this study, a multiplex PCR reaction system was successfully established, which could simultaneously detect 4 MDRAB resistance genes. 68 clinical isolates of MDRAB resistance genes showed that 1 strain carried 4 drug resistance genes and 5 strains carried bla Ade-B,. Blaint-1 and bla ISCR-1,62 strains carry blaoxa-23 and bla Ade-B. Conclusion Multiplex PCR can be used to detect drug resistance genes carried by MDRAB quickly, efficiently and at low cost. Multiplex PCR analysis shows that blaoxa-23 and bla Ade-B are the major drug resistant genes carried by MDRAB.
