Candida auris in critically ill patients: Emerging threat in intensive care unit of hospitals

Abstract

Candida auris has emerged as the multi-drug resistant non-albican candida species in critically ill patients admitted to intensive care units (ICU) causing bloodstream and other infections. It has often been misidentified as Candida famata, Candida sake, Rhodotorula glutinis, or Saccharomyces cerevisiae and Candida haemulonii by automated identification systems. We, in this study, discuss three patients who acquired Candida auris infection after 15 to 20 days of their stay in medical ICU. Medical equipment, use of multiple antibiotics, and poor hand hygiene are the most probable predisposing factors attributing to its colonization at multiple anatomical sites leading to bloodstream infection. Candida auris might substantially contaminate the environment of colonized or infected patients making its eradication difficult. Patient screening for Candida auris, especially during prolonged ICU stays, along with strict infection prevention and control strategies needs to be adopted to break its persistence.
