Immunological Effects of Probiotics

The most suitable body site for the pathogenic microorganisms and the viable material is the gastro intestinal tract. The gut-associated lymphatic tissues (GALT) play a major role in both local and systemic immunological responses. Long term feeding experiment helps to determine the immunological effects on the probiotic bacteria. The probiotic bacteria have the capacity to give rise to the immune system under some pathogenic conditions. The probiotic bacteria used to show the immunological effect was Lactobacillus species and later Bifidobacterium genus has been used, which showed the positive effect on the immune response associated with the probiotic bacteria. The primary organ of the immune system is called as innate immune system which is the principal system for having immunological effects on the probiotic bacteria and it is mediated by monocytes, macrophages and dendritic cells.
