A case of prosthetic joint infection due to the rare opportunist yeast, .

Background And Purpose: Invasive fungal infections caused by () have recently increased despite the low virulence potential of this yeast. However, limited information about the widely-used commercial biochemical identification systems has led to an underestimation of infections in clinical settings.

Case Report: This study reports a case of prosthetic joint infection in a patient who had a previous history of total knee replacement surgery. was recovered from intraoperative culture specimens identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and confirmed using molecular assays. It was, however, initially misidentified as by phenotypic identification.

Conclusion: Due to the emergence of uncommon yeast species, it is important to accurately identify and perform antifungal susceptibility testing on uncommon yeast isolates for appropriate management.
