Experimental dermatophytoses produced by E. floccosum in guinea pigs.

Experimental dermatophytoses were tested in guinea pigs by 17 strains of genus Epidermophyton. Only three strains of E. floccosum produced lesions. These lesions were detected 5-7 d after inoculation, and no crust formation or alopecia was observed. These lesions were also studied using microbiological and histopathological techniques. No infection occurred after cutaneous application of E. floccosum var. nigricans and E. stockdaleae.
