Abstract
The existence of a epizootic in guinea-pigs caused by a dermatophyte is reported. After having studied the cultural characteristics of the parasite, it was concluded to be Trichophyton gypseum granulosum (Sabouraud, 1908), not yet described as an agent of spontaneous tinea in guinea-pigs. In spite of the considerable extent of the infection, not a single case of human contagion was found among those in charge of the infected guinea-pigs, not even when dealing with the sick animals for laboratory purposes. The authors believe this to be the first description of the occurrence of a true epizootic caused by Trichophyton gypseum granulosum (Sabouraud, 1908).
