Bsal susceptibility depends on host origin but not on skin microbiota in captive Pleurodeles waltl.

ABSTRACT:

Background

Amidst the current biodiversity crisis, amphibians are particularly endangered by the emergence of infectious diseases. The skin disease chytridiomycosis is caused by the fungi Batrachochytrium dendrobatidis (Bd) and B. salamandrivorans (Bsal), which may interact with bacterial symbionts present on the amphibian epidermis. Extensive research has explored the interactions between the amphibian microbiota and Bd; yet, little is known about its interactions with Bsal. In this paper, we used the ribbed newt (Pleurodeles waltl), a model species displaying pronounced among-individual variation in response to Bsal, to (1) determine whether susceptibility to Bsal and individual microbiota vary between source groups; (2) test whether susceptibility to Bsal can be predicted from s
