Bacteria are prevented from crossing the intestinal wall by the integrity of the intestinal cells, particularly the tight junctions, as well as the mucus lining of the intestines. If bacteria make it into the interstitial space in the intestinal wall, there is a strong diffuse immune system presence in the form of the GALT (gut associated lymphatic tissue) that can quickly move to eliminate trans-locating bacteria.
However, there is no specific lymphatic organ, just a collected of lymph nodes and lymph tissues.
Peyer's patches, which are isolated clusters of lymphoid tissue.
Lactoferrin

The bacteria in the intestines is beneficial. Acidophillus bacteria as in Yogurt is also beneficial . Lactobacillus is used commercially in dairy industry widely. Escherichia coli, an intestinal bacteria helps in digestion and absorption of food . Staphylococcus aurous, a bacteria present on our skin, aids it in immunity.

It prevents phagocytosis of the bacteria and also provides mechanical protection from harmful agents and prevents drying up.
Tin is not very reactive when in contact with acidic foods so it is used to coat steel to make food cans; This prevents the food being tainted by can and prevents the food from damaging the steel can and potentially breaching its integrity.
Antilbiotics
Garlic prevents caries by killing the bacteria that causes it. Only raw garlic will have this effect, as the antiseptic compound is destroyed when heated.
disinfectant - kills bacteria ii) antiseptic - prevents bacterial growthiii) sterilisation - kills bacteria
Salt prevents the growth of bacteria.
