FIG 3.

Neighbor-joining tree based on partial 16S rRNA sequences of the family Piscirickettsiaceae revealing a sister relationship between a novel Piscirickettsiaceae ASV identified in this study and the known fish-associated pathogen Piscirickettsia salmonis. GenBank accession numbers for 16S rRNA sequences are listed to the right of each bacterial taxon, and the ASV identified in this study is labeled in red text with “ex.” followed by the host organism with which it was found to be associated. Nodes are labeled with bootstrap support values generated from 100 pseudoreplicates.
