This rapid expansion is defined by its unique population structure consisting of six distinct genomic clades with starkly different evolutionary trajectories, phenotypic traits, and clinical risks. We conducted a systematic synthesis of literature from PubMed, Scopus, and Google Scholar (2009-2026), focusing on comparative genomics, clade-specific virulence, and diagnostic accuracy. A total of 64 studies were analyzed to identify patterns in clade divergence and antifungal resistance. Our analysis reveals that C. auris is not a monolithic threat but a complex of diverse lineages with specialized adaptations. Clade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains. In contrast, Clade II (East Asian) was initially associated with localized ear infections; recent genomic data show an expanding pathogenic profile with emerging bloodstream infections. Our review also identifies Clade V (Iranian) as a genetically distinct group and highlights the recent identification of Clade VI (Indomalayan) as a distinct lineage, suggesting a long-standing environmental reservoir. Furthermore, we identify critical \"blind spots\" in automated diagnostic platforms (VITEK<sup>®</sup> 2, BD Phoenix) where phenotypic variations in Clades II and III lead to frequent misidentification as Candida haemulonii or Candida famata. This review proposes a \"clade-aware\" framework for public health. While frontline antifungal treatment remains standardized regardless of lineage, we argue that effective long-term management and outbreak containment require integrating genomic surveillance with clade-specific infection control. By identifying high-biofilm clades (Clade I) or hyper-virulent lineages (Clade IV), public health systems can implement more targeted containment strategies, moving toward a precision-based approach to managing this fungal pathogen.</p>","PeriodicalId":11782,"journal":{"name":"European Journal of Clinical Microbiology & Infectious Diseases","volume":" ","pages":"3241-3250"},"PeriodicalIF":3.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148316384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
