lol!! Oh Boy. Here we go again. Look what you yourself just posted:
"The bacteria numbers and composition in the large intestine is effectively that of fecal material."
And look what I have already stated:
"The only situation where there may be more microflora in the colon is if you are counting a very large stool that has not passed. I am referring to the intestinal lining microflora."
The other information you posted is in reference to the fluid and chime passing through the intestines. Of course the bacteria count is going to go up as it progresses down the intestines.
And let me state this. You are 100% wrong in stating that majority of the intestinal lining microflora reside in the colon.
