PERSISTENCE OF CANDIDA AURIS ON ELEMENTS USED FOR PERSONAL PROTECTION (LATEX GLOVES AND DISPOSABLE GOWN)Abstract
Candida sp. is currently associated with nosocomial infection; in this study, we aimed to determine the persistence of Candida auris on inanimate surfaces. Two test surfaces (latex gloves and disposable gown) were inoculated with two strains of Candida auris (clinical Ca1 and environmental H005913). The initial concentration of the inoculum was 108 UFC / mL, sampling was performed by rubbing a sterile swab over the surface, being sampled every 48 h, the micro organisms recovered by means of MALDI-TOF mass spectrometry were identified. The persistence of C. auris on gloves surface was 624 h equivalent to 26 days and in disposable gown C. auris clinical 528 h 22 days, C. auris ambient 576 h 24 days; With respect to death kinetics, the values obtained on the glove surface are consistent with the death curve, but unlike disposable gowns, the values were not related to the death curves. According to the results obtained, it is important to manage and control Infections associated with health care since C. auris is a microorganism that persists for many days in fomites and can generate foci of new infections.
