Breaching Pathogeographic Barriers by the Bat White-Nose Fungus

摘要

ABSTRACT Bat white-nose syndrome has become associated with unparalleled mortality in bat species across the United States since 2006. In a recent article, Drees and colleagues (mBio 8:e01941-17, 2017, https://doi.org/10.1128/mBio.01941-17 ) utilized both whole-genome sequencing and microsatellite data to explore the origin and spread of the causative agent of bat white-nose syndrome, Pseudogymnoascus destructans . The research by Drees et al. supports the hypothesis that P.?destructans was introduced into North America from Europe, with molecular dating suggesting a divergence from European isolates approximately 100?years ago. The approaches described in this study are an important contribution toward pinpointing the origins of this infection and underscore the need for more rigorous international biosecurity in order to stem the tide of emerging fungal pathogens.
