Overall structural comparison of intestinal microbiota in Groups M, F, BPA and E2.

<p><b>a)</b> Principal component analysis scores plot. b) Clustering analysis of intestinal microbiota. The triangle, rhombus, roundness and square represented samples of Groups M, F, BPA and E2, respectively.</p

Summary of intestinal microbiotic species richness estimators for sample groups.

<p>Summary of intestinal microbiotic species richness estimators for sample groups.</p

Two indices of the host evaluated the vitellogenin and triglyceride content in male zebrafish.

<p>a) The mRNA relative expression of VTG by E2 and BPA in male zebrafish liver. b) The triglyceride content in male zebrafish in muscle. Statistical analysis was carried out using one-way ANOVA. Different lower case letters represent significant differences among treatments (P< 0.05).</p

Intestinal microbiotic composition in zebrafish raised in different conditions.

<p>The pie charts represent the core microbiota of Group M (male) (a), Group F (female) (b), Group BPA (male treated with 2000 μg/L BPA) (c) and Group E2 (male treated with 2000 ng/L E2) (d).</p

Network analysis visualizing the dominant genera in Groups M, F, BPA and E2.

<p>Node sizes correspond to the mean relative abundance of each genus. The proportions of genera shared by different groups are represented by the different colors in the pie charts.</p
