Interaction Information:
Comment | Campylobacter jejuni administered orally to rats in subclinical doses led to anxiety-like behavior without an immune response. |
Formal Description Interaction-ID: 98513 |
environment Campylobacter jejuni increases_activity of phenotype |
Comment | Experimentally elevated hypothalamic-pituitary-adrenal (HPA) axis response and depression in GF rats can be reversed by administering a single bacterium, Bifidobacterium infantis, which is found predominantly in the neonatal intestinal tract, and probiotic drugs. This bacterium is defined as ‚Äúpsychobiotic‚ÄĚ due to its antidepressant effects. |

Comment | Rat offspring separated from their mother caused a decrease in swimming in the forced swimming test and increased the immobility behavior, decreased norepinephrine levels in the brain, increased peripheral proinflammatory IL-6 secretion and corticotrophin-releasing factor mRNA levels in the amygdala. Probiotic therapy has led to a reversal of behavior problems and to the normalization of the immune response and norepinephrine levels in the brain. |

Comment | The most significant results were observed in the experiment where anxiety-like behavior obtained with high-fat diet was prevented by the administration of Lactobacillus helveticus for 21 days; when the experiment was duplicated using IL-10-deficient rats, no changes in anxiety were observed. These results showed the role of the immune system in the gut-brain axis. |
