Background:

White-nose syndrome caused by Pseudogymnoascus destructans has dramatically decreased bat populations in Canada and the United States of America; it has not been detected in México.

Objective:

Characterize the mycobiota in bats that share distribution with organisms susceptible to being parasitized by P. destructans.

Methods:

Bat sampling was carried out in San Luis Potosí and Jalisco. Samples were taken from snout and wings, and cultivated on Rose-Bengal chloramphenicol agar. Samples were purified on potato dextrose agar and identified at the genus level and, when possible, at the species level based on morphology and micromorphology. Bats were identified at the species level.

Results and conclusions:

The results showed a high fungal diversity, where 32 fungi genera were identified. Acremonium, Aspergillus, Cladosporium, Penicillium, and Scopulariopsis were detected in the 17 bat species. Pseudogymnoascus pannorum was documented, but not P. destructans.
