Billions of bacteria, including many species of the genus *Lactobacillus*, reside naturally in the human body, inhabiting areas like the digestive tract, oral cavity, and female urogenital system. This natural presence is why we often associate *Lactobacillus* with good health, but its journey into our daily diet can take several paths.

First isolated from breastfed infants in 1899, *Bifidobacterium bifidum* is a key probiotic bacterium naturally residing in the human intestinal tract. Beyond its natural habitat, this beneficial microorganism is deliberately introduced into various foods and supplements to bolster gut health. The primary sources of *Bifidobacterium bifidum* include a range of fermented foods and specialized probiotic products.

The Lactobacillus genus contains over 200 species found in a vast array of habitats, from human intestines to fermented cabbage. This ubiquity prompts the question: what is the source of Lactobacillus bacteria and how does it end up in such different places?
