gillian.....not arguing....but how did the ecoli get into the bladder in the first place?

It was introduced most likely by wiping in the wrong direction!

And NO....everyone does NOT know how to wipe themselves! My niece, who's had bladder problems since childhood (surgical repair at age 5) was not told until she was in her mid-30's! Now, why my sister never told her, I dont' know.....but she'd also been under the care of several physicians over the years....and found the info in a magazine article!
