bad bacteria increase the risk of colorectal cancer「ETBFfungus」the discovery of

The “good enteric bacteria” where our health is protected

The intestine which is in our bodies (the small intestine & the colon), you think that the person whom you think that they are the internal organs in order it digests & to absorb the food, is many.But, it understood in the intestine due to former research, that it is many important functions.

For example, controlling the immunity where of immunity cell of internal 7 tenths or more gets together truly in the intestine, protects the body from the various pathogenic bacteria and the cancer, it is to reach.
It understood in addition that, the alimentary canal hormone is secreted by the fact that the food enters into the intestine, this has controlled the rise of blood glucose value and the accumulation of the body fat.

The fact that the intestine of such a function ones is helped is, the “enteric bacteria”.

In up-to-date research, the thing bacterium above how several hundred types having lived, as for the number it is found in our individual intestines that it becomes also 100,000,000,000,000.As for weight of the bacterium which is occupied in the whole intestine, approximately 1.5kg.As for half of weight of unchi it is to be the extent that the enteric bacteria, or it is that cadaver.

The function which is good to the body is done in the enteric bacteria of this enormous quantity, although the “virtue ball germ” is, it becomes cause of the various sicknesses, the “bad character germ” it is.to control this bad bacteria、if you are able to control the function of good bacteria、to get better tone of the stomach is of course、systemic disease such as diabetes、further thought and is not useful or even prevention of cancer、scholars around the world have continued to research。

elucidate the function of intestinal bacteria in the latest technology

but、to study intestinal bacteria、actually there is a big hurdle。there are a lot of intestinal bacteria can grow most of the oxygen that there is a、was difficult to culture in the laboratory。what have lived in what is the nature of any bacteria、that is was difficult to clarify。

dr. mitsuoka tomotari of riken is also a former teacher of my（professor emeritus at tokyo university）is、20in the second half of the century、developed a technique to culture the bacteria in the absence of oxygen、this became the foundation of the world’s intestinal bacteria research。but、culturable bacteria in the gut is still yet overall2～3it is thought that only a percentage。

current、we、with work on the development of a new culture method、bacterial gene that is included in the inside of poo（DNA）by examining the、also revealed that the function of intestinal bacteria culture is difficult、working on research projects that it will: blackberry to health。

for more information about specific areas of the project、have decided to introduce in more detail later in the series、first、researchers have revealed intestinal bacteria「the latest achievements related to the disease and intestinal bacteria」i seeks to know the。

it increases the risk of colorectal cancer「ETBFfungus」

first、shocking thing became clear as one of the latest research results on intestinal bacteria。in addition to the good bacteria and bad bacteria、 that may increase the risk of colorectal cancer「super bad bacteria」the presence of has become clear is that。

its name「 ETBFfungus（fragilis toxin-producing bacteria type） 」is。

ETBFfungus（fragilis toxin-producing bacteria type）

fragilis bacteria（bacteroides fragilis）it is a fungus that lives in a lot of bacteria in the colon originally、can cause the disease usually does not have。but、type of bacteria produce a toxin in this fragilis exists、it has been found to cause diarrhea in children, such as this is。

usually、ETBFtoxin of the fungus、in healthy adults does not cause noticeable symptoms。but、2006research groups in turkey in the year「in patients with colon cancer, which is a type of colon cancer、obviously compared with healthy subjectsETBFthe prevalence of high bacteria」made it clear that the。further、2009johns hopkins university research group in the year、in an experiment using mice prone to cancer「ETBFinfected with the bacteria in the colon、seen in chronic inflammation and tumor、oncogenesis has been promoted」it was reported by。

from these research results、experts 「ETBFin the large intestine of the person holding the fungus、followed by chronic inflammation within himself is unaware、colon polyp is born from a bad part of nature、or not it eventually become cancerous」 we believe。

this is、helicobacter pylori in the stomach leads to a chronic inflammation in gastric mucosa、and that it is increases the risk of gastric cancer、are very similar。

in、how many peopleETBFwhat holds a fungus。
the survey in each country about3％from about40％the result has become disjointed and in each region、in the japanese about10％it has been reported that。

bifidobacteriaBB536is、ETBFsuppress the bacteria？

of course、ETBFdoes not mean that all it takes to colorectal cancer who have the bacteria。but、by reducing the number of bad bacteria or these ultra-、lowering the risk of colon cancer might be possible。 

actual、in my laboratory、professor soichi tanabe of hiroshima university、conduct joint research with morinaga milk industry co., ltd.、bifidobacteria which serves to normalize the intestinal bacteria「BB536」by taking as a food、ETBFi was able to clarify that it can reduce the bacteria。

the next、focusing on research results、 let us introduce the relationship between colon cancer and intestinal bacteria。
