Resumen:
Objective: This study, the first of its kind that has been done in Mexico, reports the different yeast species isolated from several substrata sampled in enclosed and open spaces, which represent the ecological niches for Histoplasma capsulatum var. capsulatum. Material and methods: The substrata from which yeast isolation was performed were obtained from Quechultenango and Olinala villages located in the State of Guerrero, Mexico. Results and discussion: Candida catenulata, C. famata, C. guilliermondii, and Rhodotorula spp., were isolated from bat guano collected in caverns and caves; only C. ciferrii was obtained from one mine. The species C. albicans, C. ciferrii, and C. tropicalis were isolated from soil with fowl excreta; and C. famata, Cryptococcus albidus var. albidus, Trichosporon beigelii, and Trichosporon spp. were obtained from soil with gamecock excreta. Only C. famata was recovered from the gut of insectivorous bats; and C. lipolytica, Cr. albidus var. albidus, and Trichosporon spp. were isolated from pollinivorous bats. The distinctive characteristics of each species, as well as the environments and substrata from which they were isolated are commented.
