Isolation of Microspor Um a Udo Uin1i from a Dog *

The dermatophyte, Micros porum audouinii, is the most common cause of epidermic tinea capitis of children in this country. Epidemics involving thousands of school children have been reported from all parts of the United States. This fungus is considered by most investigators to be anthropophilic. However, there are recorded in the literature three cases of lower animal infections. In two instances M. audouinii was isolated from dogs (1, 2) and in one case from a monkey (3). That lower animals may be parasitized by this dermatophyte is apparent; however, the paucity of reported cases would indicate that such infections are rare. The present paper records the isolation of M. audouinii from a dog found to be spontaneous]y infected by this fungus.
