A recently granted patent (Publication Number: US11911423B2) discloses a method for enhancing the immune activity of the body by administering a specific strain of Bifidobacterium lactis, known as BL-99, to individuals in need of immune support. The strain, with a deposit number of CGMCC No. 15650, is administered in an effective amount to achieve the desired immune-boosting effects. The method involves various parameters to ensure the efficacy of the strain, including the form of administration, survival rates of viable bacteria in gastric acid, and specific immune markers such as carbon clearance index, half hemolysis value, antibody-producing cell number, NK cell activity, and phagocytosis rate of macrophages.

Furthermore, the patent also covers a method for improving immune activity by administering a bacteria preparation of Bifidobacterium lactis, which includes the BL-99 strain with the same deposit number. The bacteria preparation can be in the form of solid bacteria powder or liquid bacteria preparation, either in viable or inactivated form. Similar to the previous method, enhancing immune activity in this approach involves increasing specific immune markers such as carbon clearance index, half hemolysis value, antibody-producing cell number, NK cell activity, and phagocytosis rate of macrophages. The patent highlights the potential of Bifidobacterium lactis BL-99 in modulating immune responses and improving overall immune function in individuals requiring immune support.
