Ruminal bacteria and archaea composition identified by 16S rRNA sequencing of healthy and mastitic cows. (A) Venn diagram illustrating 2979 OTU of core microbiota identified by 16S rRNA sequencing of healthy (H) and mastitic (M) cows. (B) The Chao1 richness estimator and (C) Shannon’s diversity index. (D) Partial least squares discriminant analysis (PLS-DA) plot based on the relative abundance of OTUs indicates a significantly different composition of healthy versus mastitic cows. Ellipses represent 95% confidence intervals for each group. The top 10 (E) families and (F) genera identified in cow ruminal fluid, each bar refers to an individual cow.
