NO WE ARE NOT BORN WITH IT. Bacteria colonize our intestinal tracts shortly after birth through ingestion of enteric bacteria. The fetal compartment IN UTERO (WITHIN THE UTERUS) IS STERILE.
PLEASE MAKE SURE YOU KNOW WHAT YOU ARE TALKING ABOUT WHEN YOU ANSWER A QUESTION.
Colonization of the enteric system is fairly quick after birth, but it is from consuming food/water that have the bacteria in/on them. There is NO WAY bacteria can get into the fetal intestinal tract unless the mother is has bacteria in the blood (bacteremia) that makes it through the placental barrier into the fetus, which is VERY VERY BAD for the fetus. Often results in fetal abnormalities or death.

No. Babies are sterile at birth. If we had e. coli in the intestine before we were born there wouldn't be anything stopping it from killing the fetus. All babies born today have to get a vit. K shot to boost blood clotting because they don't have the bacteria in the large intestine to produce it. Babies get bacteria from mostly environmental sources, either from the mother if they are breast fed or from the water and formula if they are bottle fed.

No, in utero the fetus is sterile. The intestinal tract is colonized shortly after birth. This is why babies are often given vitamin K injections. Bacteria in the gut produce vitamin K, which is necessary for coagulation. Because babies don't have bacteria to produce it, they may have more trouble clotting.

lol, i am also asking this question 4 years..
any way, i didn't find any satisfactory explanation,for this, but i came to some instant conclusion that, by eating, any other foreign, say, food, so much of bacterias may enter our intestine and some of them (which are useful for our digestion)may get well adapted to the human intestine..
another assumption is that, they might have been prominent in our intestine, because of the mother's milk..

Yes, we receive it from our mothers.
Essential for digestion and immunity.
Humans may have become to obsessed with clean and destroyed a lot of the vital bacteria necessary for good health.
Studies now are beginning to show this wisdom.

No, we aren't. Germs appear in your intestines once your mother starts feeding you. The inside of your mother's uterus is a safe place to be, unless she has an infection which leads to septicemia (and you get infected, too).

Yes. They are necessary for digestion.

yes. We have several types, including E.coli. even from birth we are not sterile. sinc we feed from mother, and she is not sterile.... good question!
