AbstractThe chytrid fungus (Bd) is one of the main causes of recent amphibian population declines and extinctions. However, one possible disease transmission pathway remained unexplored: the insect‐borne transport between hosts. We found Bd DNA on specialized blood‐sucking midges, which could indicate the transport of alive zoospores between amphibian hosts, in this case acting as Bd carriers in the wild.Abstract in Portuguese is available with online material.
