Fig. 2. Comparison of gut microbiota composition at the phylum level in rats from each group. (A) Variation in gut microbiota composition in the cecum at the phylum level in each rat (CON: 5 control rats subjected to neither foot shock nor the avoidance/escape task procedure; LH: 5 rats diagnosed with LH; NLH: 10 rats diagnosed as not having LH). (B) Relative abundance of gut microbiota composition in the cecum at the phylum level in rats from each group. The relative abundance of Actinobacteria was significantly increased in the LH group compared to that in the control group: 1.94%±0.72% in the LH group, 1.22%±0.32% in the NLH group, and 0.46%±0.11% in the control group. The relative abundance of Firmicutes was 92.78%±1.46% in the LH group, 91.37%±1.24% in the NLH group, and 94.79%±0.98% in the control group. The relative abundance of Verrucomicrobia was 1.96%±0.30% in the LH group, 2.85%±0.49% in the NLH group, and 2.20%±0.80% in the control group. The relative abundance of Bacteroidetes was 2.67%±0.72% in the LH group, 3.91%±0.75% in the NLH group, and 2.06%±0.31% in the control group. *p<0.05 vs control rats. p-values obtained via the Kruskal-Wallis test followed by the Steel-Dwass post hoc test.
