Bifidobacterium Longum is a probiotic that lives in the gastrointestinal tract and vagina. They are the most important inhabitant in the body. These bacteria maintain a normal digestive tract, boost the immune system,and inhibits the growth of harmful bacteria. Researchers in Japan are studying the effect of Bifidobacterium Longum as a useful gene delivery tool for cancer therapy. It is among the first to colonize the digestive tract of newborns and is important for the development of immune system tolerance. The lack of tolerance in the immune system leads to allergies and diarrhea.

Lactobacillus Acidophilus is a friendly bacteria. This is considered friendly as they are healthy bacteria inhabiting the vagina as well as intestines and protect the growth or entrance of organisms causing diseases. The Lactobacillus acidophilus is acquired by various mechanisms. For instance, breaking of food by Lactobacillus acidophilus results in producing hydrogen peroxide, lactic acid as well as other byproducts, and there by make the environment hostile for organisms that are undesired. Lactobacillus acidophilus produces an enzyme called lactase that is useful in breaking the lactose into simple sugars. People lacking lactose are unable to produce this enzyme and result with symptoms such as bloating and gas. Lactobacillus acidophilus aids digestion as well as suppresses diseases causing bacteria. This is also useful in chronic constipation treatment. Lactobacillus acidophilus alleviates irritable bowel syndrome and also reduces bladder inflammation. It certainly improves the lactose absorption. Consuming milk or yogurt having lactobacillus improves the immune response naturally. As it also cures respiratory infections like bronchitis, pneumonia and sinusitis, additional research is expected.

Lactobacillus Rhamnosus is another type of probiotic. Aside from its positive effects on the intestinal tract, it also helps greatly in improving the immune system. Lactobacillus Rhamnosus signals the body to produce its natural antibiotic to fight disease and infections. It also helps in preventing diarrhea. Lactobacillus Rhamnosus aid in releasing lactic acid that keeps the harmful bactia in control. Lactobacillus Rhamnosus also causes the body to produce white blood cells or lymphocytes that fight infection. It also helps in speeding up the healing process of the body. Lactobacillus Rhamnosus works with the mucous membrane of the intestine and restores the balance of good bacteria. It also helps in diminishing the production of carcinogenic compounds.
