I was just wondering where all the bacteria in our bodies comes from? Does it enter the body through the mother during pregnancy? Also how does the body know how much to let in?
Much of it comes in through food or water- some in the air we breathe. The body does NOT "know how much to let in". But it can kill some of the bacteria. And the "beneficial" bacteria in the intestine is pretty much controlled based on how much food it gets.binbots said:I was just wondering where all the bacteria in our bodies comes from?

JorgeLobo said:We probably won't die without them but we and they have evolved together so it won't be easy wthout them - one can sustain gnotobiotic (microbe-free) animals.
bobze said:Actually we'd probably die without our bacteria. They preform a host of services for us, from helping in digestion to out-competing real "bad" bacteria. Our immune systems evolved with them as well and there is evidence that bacteria and parasites help "pacify" our immune system--Or better keep it occupied such that it doesn't start attacking self-antigens.
Hi Andy, do these germ-free animals have no bacteria in the gut either?Andy Resnick said:In practice, we would probably die. However, germ-free animals are an important component of biomedical research, and so it is clearly possible to live without bacteria present.

JorgeLobo said:No bobze - gnotobiotic concept also includes germ-free animals.

Our body's bacteria comes from a variety of sources. Some of the most common sources include the environment, food, other people, and our own bodies.
No, not all bacteria in our body is harmful. In fact, there are many types of bacteria that are actually beneficial for our health and play important roles in our body's functions.
Bacteria can enter our bodies through a variety of ways, such as through the air we breathe, the food we eat, or through contact with other people or objects. Some bacteria may also be present in our bodies from birth.
While not all bacteria in our body is harmful, some types of bacteria can cause infections and illnesses. However, our body's immune system is usually able to fight off these harmful bacteria and keep us healthy.
Yes, we can control the amount of bacteria in our body to some extent. Maintaining good hygiene, eating a balanced diet, and avoiding contact with harmful bacteria can help keep the amount of bacteria in our body at a healthy level.
