No, however, eat a lot of yogurt to keep yourself safe.
You have a lot of "good" bacteria in your intestines, these are the intestinal flora.
There are some bacteria that can cause intestinal disease. All humans have bacteria in their intestine but the bacteria is a good thing. One of the most prevalent bacteria in the human GI tract is E. coli. There are different strains of E. coli and not all of them are pathogenic. The bacteria inside the human GI tract is "normal Flora" and is beneficial to humans.
No one really knows for sure. One of the most successful current theories is that it acts as a reservoir and place of safety for the "good" intestinal bacteria.
A psychotropic has the ability to modify mental activity at body's natural chemicals. Prozac is used as anti-depressant.
Yes. For example, humans have evolved to have a symbiotic relationship with "good bacteria" in our digestive systems that keep us free of "bad bacteria". When someone is taking massive doses of antibiotics for a severe infection, the "good bacteria" that help break down the tissues of the foods to begin the process of digestion, can be killed along with the bad bacteria in a sort of "friendly fire". That leads to inability to digest foods properly and intestinal upset and diarrhea. To counter that effect, doctors will prescribe "Probiotics", supplements containing replacement good bacteria, or sometimes foods containing strains of bacteria to replace the bacteria necessary for a healthy gastrointestinal system. Some of the foods that contain microbes that are useful in this way are yogurt, some cheeses, buttermilk, and acidophiles-containing milks, to name just a few.
No. Beans usually cause intestinal gas.
Your appendix is beneficial and you should keep it if you can :) . Researchers believe the appendix is a place that "grows" and holds beneficial bacteria ("good" bacteria) and it quickly replenishes your digestive tract if you lose a lot of good bacteria all at once (like if you get diarrhea or have to fight an intestinal illness). You can live without it, but you can fight off diseases and parasites better if you have it. If your appendix is inflamed, however, something has gone wrong and it is full of harmful bacteria, which is why your body goes septic (is filled with bad bacteria flooding the blood) if the appendix bursts.
Bacteria is good and bad for you.
Yes, this would be a good idea. The human intestinal tract has billions of bacteria including E. coli, Salmonella and Campylobacter, all of which can cause illness in their host if ingested.
Intestinal bacteria provide us with vitamin b and vitamin k, and they help us digest our food. Your gut provides a very good environment for the bacteria to prosper. Both you and the bacteria benefit. The "type" of symbiotic relationship is mutualistic. see the definition of symbiosis here: http://animaldiversity.ummz.umich.edu/site/glossary/page/s.html
Because they has good amount of intestinal microbes
it is a good bactiria.
