Gut-associated lymphoid tissue (GALT) [1] is a component of the mucosa-associated lymphoid tissue (MALT) which works in the immune system to protect the body from invasion in the gut. Owing to its physiological function in food absorption, the mucosal surface is thin and acts as a permeable barrier to the interior of the body. Equally, its fragility and permeability creates vulnerability to infection, and, in fact, the vast majority of the infectious agents invading the human body use this route [2]. The complex function of the Gut-Associated Lymphoid Tissue is the critical protective immune system in the GI tract. The GALT is the most prominent part of mucosal-associated lymphoid tissue in our body and represents almost 70% of the entire immune system [3].
