TCDD enriched Lactobacillus species in the cecum microbiota. Taxa abundance were assessed in metagenomic cecum samples from male C57BL/6 mice following oral gavage with sesame oil vehicle or 0.3, 3, or 30 µg/kg TCDD every 4 days for 28 days (n = 3). Significant shifts in relative abundances of taxa are presented at the (A) phylum, (B) genus, (C) and species levels. Significance is denoted with an asterisk (*; adjusted p-value < 0.1).
