A 37-year-old woman with leukemia developed a rare blood infection caused by a yeast called Sporopachydermia lactativora, which had never been documented to cause bloodstream infection in China before. This yeast is naturally resistant to a common class of antifungal drugs called echinocandins, making it particularly challenging to treat. However, the patient responded well to a different antifungal medication called voriconazole and fully recovered. The researchers suggest that this unusual yeast should be monitored in hospitals as it could become a more common infection in vulnerable patients.
