| Abstract: | ObjectiveTo analyze the effectiveness of colloidal gold immunochromatography for rapid detection of carbapenemase-resistant Enterobacteriaceae(CRE) carbapenemase.MethodsA total of 80 CRE strains isolated from The First Affiliated Hospital of Bengbu Medical College and 21 strains of Enterobacteriaceae susceptible to carbapenem antibiotics were collected.PCR was used to detect blaKPC, blaNDM, blaIMP, blaVIM and blaOXA-48 genes as gold standard.Colloidal gold immunochromatography was used to detect the carbapenemase produced by CRE, which was conducted by the consistency analysis and efficiency evaluation combined with PCR results.ResultsAmong 80 CRE strains, 79 strains expressing carbapenemase genes were all positive for the detection of carbapenemase by colloidal gold immunochromatography, which includes 61 strains producing KPC, 10 strains producing NDM, 6 strains producing IMP and 2 strains producing VIM enzymes, the colloidal gold test results of 21 sensitive strains were negative.Compared with the PCR results, the sensitivity and specificity of the four enzymes by colloidal gold immunochromatography were both 100%, and the Kappa value was 1.ConclusionsColloidal gold immunochromatography can be applied as a simple, rapid, sensitive and specific diagnostic method for the detection of CRE carbapenemase, which is significant to the rationalization in the clinical use of antibiotics. |
