Micro 60: Laboratory Diagnosis of Fungal Disease
This episode returns to the laboratory, focusing on diagnostic strategies specific to fungi. Drawing from Murray’s Chapter 60, it explores how identification relies heavily on morphology, growth characteristics, and targeted antigen detection.
Unlike many viral diagnoses, fungal identification frequently begins with direct microscopy:
* Potassium hydroxide (KOH) preparations
* Calcofluor white staining
* Histopathology with special stains
Culture remains central. Fungi often grow more slowly than bacteria, requiring specialised media and extended incubation. Colony morphology, hyphal…
