AI Article Synopsis
- Globalized infectious diseases, particularly a fungus affecting amphibians, are leading to significant species declines around the world.* -
- Whole-genome sequencing revealed that the source of this devastating fungal panzootic is linked to the Korean peninsula, specifically a lineage called ASIA-1.* -
- The pathogen's emergence is traced back to the early 20th century, coinciding with increased global amphibian trade, highlighting East Asia as a key area for biodiversity and the origin of harmful lineages.*
Article Abstract
Globalized infectious diseases are causing species declines worldwide, but their source often remains elusive. We used whole-genome sequencing to solve the spatiotemporal origins of the most devastating panzootic to date, caused by the fungus , a proximate driver of global amphibian declines. We traced the source of to the Korean peninsula, where one lineage, ASIA-1, exhibits the genetic hallmarks of an ancestral population that seeded the panzootic. We date the emergence of this pathogen to the early 20th century, coinciding with the global expansion of commercial trade in amphibians, and we show that intercontinental transmission is ongoing. Our findings point to East Asia as a geographic hotspot for biodiversity and the original source of these lineages that now parasitize amphibians worldwide.
