FIG 1.

Color-coded bar plot showing the distribution of bacterial groups across the 82 samples from 7 individual herds. The bacterial sequences that could not be determined to the species/phylotype level were designated Bacteria spp. Spirochaeta/Treponema spp., Treponema KO1_aai43a12, and Treponema SP2_g07_2 were treated as separate groups, since they were among the most prevalent of the non-DD-related amplicons. Sequences homologous to the 14 DD-associated phylotypes were included in the DD Treponema group.
