The strain was analyzed using a comprehensive laboratory workflow that included conventional culture, light microscopy, scanning electron microscopy (SEM), and molecular identification based on rDNA sequencing. Phylogenetic analysis was conducted to assess the genetic relationship with reference strains. Antifungal susceptibility testing and in\u00a0vitro Titan cell induction assays were also performed.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Conventional MALDI\u2010TOF MS failed to identify the strain, while rDNA sequencing confirmed\n                      <jats:italic>N.\u2009uzbekistanensis<\/jats:italic>\n                      . Cryptococcal antigen testing yielded a weakly positive result with the pure culture supernatant, while the patient's serum remained negative. The strain showed markedly elevated MICs for echinocandins, flucytosine, and fluconazole, whereas MICs for voriconazole, itraconazole, and amphotericin B were comparatively low. Microscopic examination revealed round yeast cells without pseudohyphae. SEM showed globular cells enveloped by a fibrillar network. Titan cell formation was not observed.
