Trichophyton mentagrophytes infection in laboratory white mice

Trichophyton mentagrophytes infection was studied in a breeding colony of 42 white mice. Symptoms were observed in only 3 out of the 12 animals shown to carry dermatophyte on their coats. Literature on Trichophyton mentagrophytes infection mice is reviewed. The use of the technique developed by Mariat & Tapia (16) to isolate dermatophytes on cultures, specially for epidemiological surveys, is postulated. Attention is called to the importance of healthy animals, directly or indirectly, as carriers of fungi and sources of infection to other animals and human beings.
