Figure 5 Differences in the relative abundance of the skin microbiota at the genus level in three groups. (A) Bacterial abundance; (B) Streptococcus; (C) Corynebacterium; (D) Fungal abundance; (E) Malassezia; (F) Candida. Significant differences in the Figures are shown by *p < 0.05, **p < 0.01, and ***p < 0.001. Differentially abundant genera and species between the B2 and B3 skin microbiomes, as identified using linear discriminant analysis effect size. (G) Bacteria with statistical significance cut-offs set at LDA > 2.5 and p < 0.05. (H) Fungi with statistical significance cut-offs set at LDA >3.5 and p < 0.05.
