Lactobacillus rhamnosus Lactobacillus rhamnosus is primarily found in the small bowel and vaginal tract. It is very prolific in growth, has a high tolerance (resistance) to bile salts, adheres to the intestinal mucosa and protects the intestinal tract against the invasion of harmful microorganisms.
