So....we devolop from two little cells...the egg and the spermatoza thingy. They dont have bacteria in them. Where does our gut flora come from?
 
From everywhere. From the moment you're popped out, so to speak, the critters start colonising your gut, your skin, your mucous membranes, your eyes, your 'alles'...

Here's a little tidbit that might freak some people the hell out, but that I find immeasurably cool... you carry around 10 times more foreign cells around with you than what you do human cells. Each one of us is a walking ecosystem.

Cool. :-)

But how do they manage to get into your gut though? Do they squeeze through your anoos and migrate upwards? I heard that pro-biotics is almost useless because the cultures in it cant survice your tummy acid so that cuts off that route?
 
I think you get most of the starting bacteria from your mom / the womb: definitely get your immunity system from your mom ...

That said: I studied computers not biology ...

Well, a baby wouldn't be born with a fully functioning and balanced digestive system, partly because all the little buggers we carry around have to establish themselves first. It's also not something that should be viewed in isolation; the bacteria that do make it into an infant's mouth and nasal passages, and onto his skin, and wherever else, would affect the immune system & make it easier for further colonies to establish themselves elsewhere.

As for stomach acid: bacteria might not survive it but bits of food or other matter containing them could, I suppose, survive into the intestines.

Gut flora's also just a small part of it... I dig the little guys we carry around in our eye lashes. :p

Anyone that has ever had a child should know that the first few days of poop is totally different than anything you get after. The reason for this is ^.
 
Thank the gods for good flora, -was prescribed, scratch that, over prescribed antibiotics for an urethra infection....after completing my course, which lasted 5 days....- I had issues with bloatedness, food and medicine allergies, which I never had..... half my face would go all hive on my ass,....all because my course of antibiotics had wiped out most of my good bacteria in my gut...took me nearly two month of, probiotics and careful selection of what i ate, before normality returned...-so just be glad you have the little buggers working away in your system.

Something I came across a number of years ago, but Wiki seems to agree with me:
1. Steinhoff U (June 2005). "Who controls the crowd? New findings and old questions about the intestinal microflora"
