The affected site is carefully washed with 70% alcohol and after drying, the lesion is scraped with a sterile scalpel and the material obtained is placed in a sterile container, a Petri dish or a piece of white paper folded to prevent loss of the specimen. Hairs from infected areas are clipped or plucked and sent to microbiology in a similar manner.
Genital:
