First report of infection by Debaryomyces spp. in Myotis velifer (cave myotis) in Mexico

Anotace: Interest in the study of mycotic diseases in bats has increased after the identification of bats affected by white-nose syndrome in the northern United States. In a temperate forest of the community of San Pedro Yolox, Ixtlán in the Sierra Madre de Oaxaca, Mexico, we collected bats of various species, including 13 specimens of Myotis velifer that showed lesions in the plagio- and uro-patagium. Clinical exploration, histopathological studies and molecular analysis were carried out to determine the causal agent of the lesions present in these individuals. It was determined that the cause was the pathogenic fungus Debaryomyces spp. The present study represents the first report of fungal infection in bats in southern Mexico.
