Microsporum persicolor, a rare zoophilic dermatophyte, was isolated from three dogs with skin disease of between three and five years duration. Skin lesions consisted of scaling with minimal alopecia or erythema. Severe inflammatory changes were not observed clinically and pruritus was absent or mild. The face was affected in all three cases and more widespread lesions were found in two. The diagnosis of dermatophytosis was confirmed in each case by the demonstration of fungal hyphae in the epidermal stratum corneum on examination of skin biopsies. However, hair shaft invasion was not observed in either skin scrapings or histological sections. Of the three dogs, one partially improved following repeated courses of treatment, a second completely recovered with 11 weeks of combined topical and systemic therapy. Response to therapy could not be assessed in the remaining case.
