Abstract
Background and Purpose
Invasive fungal infections caused by Cyberlindnera fabianii (Cy. fabianii) 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 Cy. fabianii 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. Cy. fabianii 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 Candida utilis 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.
