Identificación de cepas del complejo Candida albicans aisladas de muestras clínicas en la región de Valparaíso, Chile.

Introduction: C. albicans is recognized as the most virulent species of the genus and represents the major cause of candidiasis in humans. At the taxonomic level, C. albicans is classified as a complex of closely related species that includes C. albicans sensu stricto (s.s), C. dubliniensis, and C. africana. Objective: to identify the species of the C. albicans complex isolated from different samples of patients from the fifth region of Valparaíso. Materials and method: 103 strains of the C. albicans complex were identified, isolated from superficial and deep samples during the year 2020. The identification was carried out based on morphophysiology and the amplification of the HWP1 gene. Results: 100 strains were identified as C. albicans s.s, 2 as C. dubliniensis and 1 as C. africana. Within the strains identified as C. albicans s.s, 4 patterns of fragment sizes were observed. Conclusions: C. albicans s.s was the most frequent species and based on the HPW1 genotype, four patterns are described (H1 to H4). [ABSTRACT FROM AUTHOR]
