Fig. 3From: Salmon gut microbiota correlates with disease infection status: potential for monitoring health in farmed animalsMicrobial composition of the investigated groups and groups beta diversity. a Barplots depicting the microbial composition of the investigated groups (see Fig. 1 for definition) shows that they are dominated in the composition by two OTUs: Aliivibrio sp. and Mycoplasma sp. Specific shifts in the relative abundance of the two highly abundant OTUs across groups are visualized. b Clustering based on beta diversity (represented as a dendrogram) is mainly determined by the relative abundance of the two dominating OTUs as shown by the heatmapBack to article page
