In looking for the study of healthy volunteers who regularly ate probiotics in the form of fermented foods and showed a marked decrease in intestinal populations when they went probiotic free for a time, I found the study below that says that at least some probiotics set up shop in our systems.
Volunteers who were having colonoscopies had their colon walls tested for the presence of the probiotic strain.

Persistence of Colonization of Human Colonic Mucosa by a Probiotic Strain, Lactobacillus rhamnosusGG, after Oral Consumption - Minna Alander1, Reetta Satokari1, Riitta Korpela2, Maija Saxelin2, Terttu Vilpponen-Salmela3, Tiina Mattila-Sandholm1, and Atte von Wright1,*
Quote:
The present study confirms that L. rhamnosus GG is able to attach in vivo to colonic mucosae and to persist there for prolonged periods after discontinuation of administration of strain GG. In accounting for the findings reported here, the study of fecal samples alone may underestimate colonization by probiotic strains.

Here's another study that says there is colonization

Colonization and Immunomodulation by Lactobacillus reuteri ATCC 55730 in the Human Gastrointestinal Tract by N.Valeur etal.
I've stopped looking for that other study.
