Candida auris overview|Overview
Candida auris is a fungus, recently described as a rare cause of fungal infection with significant resistance to antifungal medications.[1] It was first described in the year 2009 in Japan,[2] and since then, reports of C. auris infection has been published from several countries.[2] Serious and prolonged outbreaks have been documented with data showing an innate resilience of C.auris for survival, persistence in the clinical environment with the ability to rapidly colonize patient's skin, and high transmissibility within the healthcare system.[4] The precise mode of transmission within the healthcare facility is unknown.[3][4] The high rate of therapeutic failure noted in cases of Candida auris fungemia poses significant concerns.[1] Misidentification of C.auris with related Candida species such as Candida haemulonii by commercially available biochemical-based tests poses a challenge.[3] C. auris is recognized as a globally emerging fungal pathogen.[5][6] Institution of key infection prevention and control measures[4] and, correct identification and standardized antifungal susceptibility testing for optimal management strategies of patients with invasive infections can hardly be overemphasized.[4]
Candida auris historical perspective|Historical Perspective
- C. auris was first described in 2009 after being isolated from external ear canal discharge of a patient in Japan.[2]
- C. auris was incidentally found by molecular identification of bloodstream isolates of unidentified yeasts recovered in 1996, suggesting the paucity of isolation of C. auris may partly reflect the difficulty in identifying the specie.[7]
- The occurrence of C. auris in nine countries on four continents since 2009 has been reported.[3]
- C. auris infections have most commonly been hospital-acquired and occurred several weeks into a patient’s hospital stay.[3]
- It has been documented to cause infections in patients of all ages.[3][7]
- Patients were found to have similar risk factors for infections with other Candida spp.[3]
Candida auris pathophysiology|Pathophysiology
- High potential for nosocomial horizontal transmission.[6][8]
- The exact mode of transmission is unknown.[3][4]
Candida auris infection|Infection
- C. auris is a novel ascomycetous yeast species belonging to the genus Candida,[9] that can cause invasive infections, and it is associated with high mortality.[2]
