Dermatology
The direct detection of fungus elements in native preparations is usually carried out in brightfield microscopy after the sample material (skin scales, hairs, nails) has been macerated. Alternatively, incident-light fluorescence can be employed for this detection. This requires the staining of the specimen with suitable fluorescence markers, e. g. Mykoval. This marker couples to certain polysaccharides and to the chitin in the cell wall of fungi.
Through illumination with ultraviolet light, fungus elements in the specimen are displayed with high contrast against a black background. Due to its higher sensitivity, this method is faster and particularly helpful in difficult diagnostic situations.
