Response of fire salamander skin microbiota to Bsal infection. (a) qPCR estimates of bacterial density (rRNA copies/mm²), (b) species richness (sOTU richness) of skin bacterial communities and (c) bacterial community structure on control and Bsal-exposed salamanders. Bacterial community structure is visualized with Principal coordinate analysis of the weighted Unifrac distances. (d) Six representative sOTUs identified by LEfSe to be differentially abundant on Bsal-exposed individuals and control individuals.
