Another scientist, Arnold Cantani, treated pulmonary tuberculosis by spraying Bacterium terumo directly into patients lungs and this proved surprisingly effective. Simply put, probiotics are bacteria that are cultured in the laboratory and then used in high concentration to re-balance the microflora of the gut. The gut of an adult human contains approximately 1.6 2.0Kg of bacteria. It is estimated that as many as 400 types of different bacteria are normally present. Each type of bacteria has many different strains.
Some strains are specific to humans, whilst others only exist in different animals.
It is a delicately balanced ecosystem, absolutely necessary for health. The microflora in the gut play a major role in the function of the digestive system, helping the breakdown of food into simpler, usable forms which can then be absorbed by the body. Some bacteria, such as the Bifidobacteria , even synthesise various vitamins including B1, B2, B3, B6, B12, folic acid and biotin. The microflora also has a major influence on the status of our immune system, determining the ability and efficiency of the host to recover from infections, especially that of the digestive tract. Also, the level of friendly bacteria decline in middle age.
