Antibiotic effects on microbiota. (a) Heatmap of microbial taxa that were differentially expressed due to antibiotic treatment in mice before (Pre-PK) and after (Post-PK) Vitamin K supplementation. Selected taxa displayed relative abundances >1%, a Linear Discriminant Analysis (LDA) log-score >2.0, and p < .05 by the Kruskal–Wallis test. The complete list is provided in Table S3. Color intensity indicates increasing relative abundances. (b–c) Bar plots showing relative abundances of bacteria at the phylum level b) prior to PK supplementation and (c) at the end of the study following PK supplementation.
