A DEICODE biplot using Aitchison distance. The principal components represent ~ 93% of variance. Principal component 1 (PC1) is negatively correlated with the abundance of Streptococcus but positively with Moraxella, Fusobacterium, and Escherichia-Shigella while principal component 2 (PC2) is positively correlated with Escherichia-Shigella, Mycoplasma, and negatively with Streptococcus. The arrow directions point to the increased log ratio between the features. Others refers to other observed S. suis serotypes (3, 4, 5, 7, 8, 10, 11, 12, 15, 16, 28, 29, 30 and 31). B The DMM model community types. B.1 the variable importance and the leading taxa of community type one that dominated with Streptococcus along with Moraxella, Bergeyella, and Veilonella. B.2 the variable importance and the leading taxa of community type two that dominated with Escherichia-Shigella along with Pasteurella, Trueperella, and Mycoplasma. The values of importance are scaled to relative abundance and transformed to square root
