Resumen:
Objective: The species of filamentous fungi associated with the environments and substrata from which Histoplasma capsulatum has been isolated were studied from the gut of infected bats as well as from bat guano and bird droppings. Material and methods: Samples were collected from several caves and other localities of the State of Guerrero, Mexico, mainly Juxtlahuaca and Olinala. Results and discussion: Ascomycetes, such as Aphanoascus fulvescens, Gymnascella citrina, Gymnoascus dankaliensis (Onygenales), and Chaetomidium fimeti (Sordariales); conidial fungi, such as Aspergillus flavo-furcatis, A. terreus, A. terreus var. aureus; various undetermined species of Penicillium, Malbranchea aurantiaca, and Sporothrix sp., were isolated from bat guano. Phoma sp. was isolated from gamecock excreta. Several species of conidial fungi: Aspergillus candidus, A. flavo- furcatis, A. sulphureus, A. sydowii, A. terreus, A. versicolor, Aspergillus sp., M. aurantiaca, Gliomastix murorum, Scopulariopsis sp., and only the ascomycete Ch. fimeti, were isolated from the gut of insectivorous, hematophagous, nectarivorous, and frugivorous bats. Some biological properties of these fungi are commented, most of which are reported for the first time for these substrata and environments in Mexico.
