Study of immunotropic activities of Bacillus subtilis as the basis of anti-scleroma probiotics.

Presence of influence of Bacillus subtilis during peroral and parenteral administration upon the laboratory animals' immune system has been studied. Absence of immuno-depressing action of the bacillus culture under study has been presented with the help of assessment tests on the humoral response to the thymus-dependent antigen: creation of the antibodies, and the delayed-onset hypersensitivity reaction. An insignificant stimulating effect has been revealed under execution of the reaction of the delayed-onset hypersensitivity as a result of B. subtilis application. The obtained data confirm the prospects of application of the B. subtilis strain as a basis of the anti-scleroma probiotics.
