Hierarchal clustering using Ward’s agglomeration method on all liver abscess communities (n = 53) collected from 20 animals with liver abscesses illustrating the relatedness of communities classified as high Fusobacteria (dark red boxes), high Bacteroidetes (orange boxes), or high Firmicutes (magenta boxes) based on the parameters set in Pinnell et al., 2022. These community types are further classified into three clades with markedly different community structure; a Fusobacteriaceae-dominated clade (clade 1, purple dashed outline), a high Bacteroidaceae clade (clade 2, sea green dashed outline), and high diversity clade comprised primarly of Bacteroidaceae, Porphyromonas, Peptostreptococcales-Tissierellales, Actinomycetaceae, and Peptostreptococcaceae (clade 3, olive green dashed outline). The text within the boxes represents the animals the abscess was collected from, with ‘T’ signifying an animal that received tylosin supplementation and a ‘C’ signifying an animal that did not. The bar plot illustrates the relative abundance of microbial families with each individual sample. The 8 most abundant families are displayed in the legend
