Fungal Elements in KOH Mount of Sputum Microscopy-Introduction, Fungal Elements Observed in Sputum KOH Mount, Applications, and Keynotes

Fungal Elements in KOH Mount of Sputum Microscopy at a magnification of 1600X

Introduction KOH mount of sputum is a rapid, direct microscopic technique used to detect fungal elements in the respiratory tract. A 10–20% Potassium Hydroxide (KOH) solution digests mucus, epithelial cells, and debris in sputum, while preserving the chitin-rich fungal cell walls, making them appear clear, …

Funguria-Introduction, Common fungi, Clinical Feature, Lab Diagnosis, Treatment, and Prevention

Urine sample for fungal culture and KOH mount

Introduction Funguria refers to the presence of fungi in the urine, either due to colonization, contamination, or true urinary tract infection (UTI). It is increasingly reported in hospitalized or catheterized patients, particularly those with immunosuppression, antibiotic overuse, or diabetes. Most cases are asymptomatic, but it …
