It is well-known that the intestinal microbiota influences the host's health, including the activities of the central nervous system. This phenomenon is known as the brain-gut axis. Mental and emotional disorders are now fairly widespread. Many of them are lifelong, and medications frequently cause side effects. Not surprisingly, researchers have been drawn to the study of probiotic bacterial cultures as an adjunct or primary therapy for psycho-emotional illnesses. There is a lot of evidence that bacterial strains from the genera Bifidobacterium and Lactobacillus have a favorable influence on the activities of the central nervous system. However, the effect of Bacillus spp. on the behavior is not clearly known. In contrast to Muc2-/-, the wild type mice (Muc2+/+) have normal gut barrier function, but the intestinal microbiota and behavior are similar to their mutant siblings Muc2-/- mice. Similar to the mutant sibling, Muc2+/+mice exhibit greater locomotor activity in the open field and light-dark tests, as well as decreased anxiety in the open field test, light-dark test, and marble burying tests. The addition of kanamycin-resistant strain Bacillus subtilis BS20 spores to the diet of Muc2+/+ mice for 3 weeks at 107 CFU/g led to a change in behavior and cytokine levels in the gut compared to control C57BL/6 mice. Furthermore, a drop in serotonin and a rise in tyrosine were identified in the blood serum. Changes in cytokines, serotonin, and tyrosine levels may mediate the normalizing impact of B. subtilis spores on Muc2+/+ mice behavior.
