#MicrobiologyMonday: Guess the microbe! 🔬🧐

Meet Saprochaete capitata, a yeast-like fungus found in soil. Usually harmless, it can cause severe infections in immunocompromised patients.

For an example case, check out #ASMCaseReports: asm.social/2BK
Growth of S. capitata on Sabouraud dextrose agar (left) after 5 days of incubation at 30°C in ambient air produced white, fuzzy colonies. The microscopic morphology stained with lactophenol cotton blue (right) highlights the appearance of oblong annelloconidia clustered at the tips of the annellides, which are located along or at the tips of the hyphae.
