Fig. 1From: Compositional analysis of the tonsil microbiota in relationship to Streptococcus suis disease in nursery pigs in OntarioA Rarefaction curves that estimate microbial diversity of three diagnosis groups. The lines represent the different sampling depth across the samples. B Phylogenetics (PD) and non phylogenetics (Observed ASVs and Shannon) alpha Diversity metrics among the 57 rarefied samples (18 confirmed, 17 healthy, and 22 probable cases) on 9 swine farms. The probable group had the highest level of phylogenetics diversity while the confirmed group had the lowest observed ASVs. Asterisks indicate significant differences between diagnosis groups *p < 0.05. C Non-metric multidimensional scaling (NMDS) plot of Bray–Curtis dissimilarity distance index for 57 rarefied samples (18 confirmed, 17 healthy, and 22 probable pigs) on 9 swine farmsBack to article page
