Resident bacteria strains, or permanent gut dwellers, live on the walls of your intestinal tract. They form a protective layer against pathogenic ("unfriendly") germs there.
Transient probiotic strains, or temporary visitors, follow the digestive process and are eventually evacuated from the body. They are helpful in fighting certain types of bacteria, and are important to the immune system.
Resident strains:
Lactobacillus helveticus, Lactobacillus acidophilus, Bifidobacteria bifidum, Bifidobacteria breve, Bifidobacteria longum, Bifidobacteria infantis, Lactobacillus animalis, and Lactobacillus rhamnosus.
Transient strains:
Lactobacillus casei, Lactobacillus plantarum, Lactobacillus paracasei, Lactobacillus bulgaricus, Streptococcus thermophilus, and Brevibacillus laterosporus.
