An Xpert screen to identify carbapenemases

Indian J Med Microbiol. 2016 Apr-Jun;34(2):216-8. doi: 10.4103/0255-0857.176845.

Abstract

To prevent the spread of carbapenemases-producing Enterobacteriaceae (CPE) active surveillance, contact isolation and cohorting infected patients should be practiced. Rectal swabs for the Xpert MDRO-assay of 32 patients were included. 71.85% were positive for targets incorporated into the MDRO-assay; whereas 28% were phenotypically not CRE and Xpert negative (9.37% had different mechanism [bla OXA]). The assay identified 59.3%, 9.37% and 3.1% as bla NDM, bla NDM+VIM and bla VIM, respectively. The assay is a screening test that identifies CPE harbouring organism within an hour and can be installed at tertiary-care facilities to screen colonized patients.
