List of 37 OTUs that differed significantly in relative abundance among microbiota manipulation treatments (antibiotics, augmented with <i>J</i>. <i>lividum</i>, and unmanipulated) 7 days after exposure to Bd, based on a Kruskal-Wallis test with Bonferroni corrected P values.

Taxonomy includes the phylum and the lowest classification that could be defined for each OTU. Phyla are abbreviated as follows: Act = Actinobacteria, Bac = Bacteroidetes, Pro = Proteobacteria. OTUs are ranked in order of relative abundance in the unmanipulated treatment. The Comamonadaceae OTU that was positively correlated with frog growth among Bd-exposed frogs is bolded. Representative 16S rRNA gene sequences for these 37 OTUs can be found in S1 Text.
