First Isolation of Pseudogymnoascus destructans, the Fungal Causative Agent of White-Nose Syndrome, in Korean Bats (Myotis petax).

ABSTRACT: White-nose syndrome (WNS), caused by Pseudogymnoascus destructans (Pd), is a lethal fungal disease that affects hibernating bats in North America. Recently, the presence of Pd was reported in countries neighboring Korea. However, Pd has not been investigated in Korea. Therefore, this study aimed to identify the presence of Pd in Korean bats. Altogether, wings from 241 bats were collected from 13 cities and cultured. A total of 79 fungal colonies were isolated, and two isolates were identified as Pd using polymerase chain reaction. Of the nine bat species captured in 13 cities, Pd was isolated only from Myotis petax in Goryeong. Atypical, curved conidia were observed in two isolated fungal colonies. Although histological lesions were not observed by hematoxylin and eosin or periodic acid-Schiff staining, fungal invasion was observed in the tissue sections. Taken together, these results confirmed the presence of Pd in Korean bats and suggest the possibility of WNS outbreaks in Korean bats. This is the first report of the isolation and molecular analysis of Pd from Korean bats.
