The invention relates to the technical field of microorganisms, in particular to
lactobacillus kefir and application thereof in the aspect of regulating animal immune functions. The invention provides
Kefir lactobacillus brachyphyllum Fanghua, and the preservation number of the
Kefir lactobacillus brachyphyllum Fanghua is CGMCC (China General
Microbiological Culture Collection Center) NO.27733 Research finds that compared with an
immunosuppression model mouse constructed by using
hydrocortisone, the weight of immune organs thymus and
spleen can be increased, the number of
peripheral blood leucocytes can be increased, and immune
cell composition and expression of
inflammation-related genes can be changed when the mouse is fed with the
Lactobacillus kefir Fanghua. Besides, after the excrement of the aged mice fed with the lactobacillus
kefir Fanghua is transplanted to the sterile mice, compared with excrement only transplanted to the aged mice, the content of dendritic cells in the
spleen of the
receptor mice can be reduced, differentiation of
helper T cells can be inhibited, expression of
inflammation-related genes can be remarkably reduced, and the
inflammation-related effects can be improved. Further, the immune
inflammatory response of the
receptor mouse is regulated.
