From: The microbiome associated with equine periodontitis and oral health
Diversity analysis on equine microbial profiles at health and periodontal disease. A Observed species richness or number of OTUs/sample; B estimated species richness or Chao-1 and C Shannon diversity index. Healthy microbiomes were statistically significantly less diverse than microbiomes with periodontal disease (p < 0.001, Mann–Whitney test).
