Once fungal collections populate the sample, morphological examination can be conducted and completed. Morphological analysis is used to distinguish Microsporum species from other keratin-loving dermatophytes. [7] To accurately decipher Microsporum gypseum and Microsporum fulvum from one another, many researchers use genetic analysis procedures ...
