| Abstract: | Recently a new taxon of geophilic dermatophytes was established as Microsporum appendiculatum Bhat and Mariam, based on the presence of appendaged macroconidia. However, such appendages are already known in the related
species Microsporum gypseum. We conducted a survey of soil in central India as a part of a microbial biodiversity project and obtained two strains of
M. gypseum with appendaged macroconidia. Using phenotypical characterization in combination with sequencing and restriction fragment
length polymorphism (RFLP) of the Internal Transcribed Spacer (ITS) region of rDNA, we found that all strains of appendaged
species are identical. Therefore M. appendiculatum is regarded as a synonym of M. gypseum. |
