Evaluation of Eazyplex® LAMP test for fast Candida auris direct detection of colonized patients

Abstract

Candida auris is a multidrug‐resistant pathogen yeast that produces nosocomial outbreaks, due to its ability in colonizing the skin, mucous membranes and surfaces. Rapid diagnosis is essential to control its spread. The aim of this study was to compare the Eazyplex® Candida auris kit (AmplexDiagnostics GmbH) for the rapid identification of patients colonized with C. auris, with the reference method used in our institution (culture and identification by MALDI‐TOF). This easy‐to‐perform test allows obtaining a fast result, in ~30 min. First, we achieved a preliminary study from previously characterized Candida species colonies obtained from 51 clinical samples, with 100% agreement between culture isolation and the Eazyplex® Candida auris LAMP. Second, 152 epidemiological surveillance samples (pharyngeal and axillary‐rectal swabs) were tested retrospectively. The sensitivity, specificity, positive and negative predictive values were 91.8%, 98.8%, 98.2% and 94.5%, respectively. Eazyplex® Candida auris showed acceptable results compared with culture in detecting C. auris from surveillance samples with the advantage of single‐test and shorter time for handling and result than culture, in addition to its great specificity, positive and negative predictive values.
