Vaginal: strains named in the research

Lactobacillus crispatus is a lactic acid bacterium native to the human vaginal microbiota.

Lactobacillus acidophilus is one of the most studied lactic acid bacteria, with research dating back decades documenting its ability to survive the harsh conditions of the gastrointestinal tract, including acid and bile …

Lacticaseibacillus rhamnosus, most widely studied as the GG strain, has an extensive research record, though the evidence base in this index is predominantly in vitro and animal-model work.

Lactiplantibacillus plantarum (formerly Lactobacillus plantarum) is a well-characterized lactic acid bacterium found across fermented foods, the human gut, and diverse environmental niches.

Lactobacillus casei (species-level entry, undesignated strain) is a broadly studied lactic acid bacterium encountered across fermented dairy and non-dairy foods.

Lactobacillus gasseri is a species naturally found in the human vaginal and gastrointestinal microbiota, and the papers indexed here reflect a broad species-level literature rather than a single defined strain.

Limosilactobacillus reuteri RC-14 has been studied primarily in the context of urogenital and oral health, often in combination with its companion strain L.

Lacticaseibacillus casei (species-level entry, no specific strain designation) is a broad species grouping that includes well-studied commercial strains such as L.

Lacticaseibacillus rhamnosus GR-1 is among the most thoroughly researched probiotic strains for urogenital health, with multiple randomized controlled trials evaluating its oral use in relation to vaginal microbiota comp…

Lactobacillus johnsonii is a facultative anaerobic lactic acid bacterium originally isolated from the human vaginal microbiota.

Lacticaseibacillus paracasei (the species, without a designated strain identifier) is a broadly distributed lactic acid bacterium found in fermented foods and the human gut.

Lactobacillus crispatus CTV-05, marketed as LACTIN-V, is a vaginally administered live biotherapeutic product studied in one of the more extensive clinical development programs among probiotic strains.

Lactobacillus helveticus is a lactic acid bacterium widely used in dairy fermentation and probiotic applications.

Bifidobacterium breve is a species commonly found in the human gut, particularly in breastfed infants, where it plays a role in fermenting complex carbohydrates including human milk oligosaccharides.

Bifidobacterium longum is a well-characterized commensal species found throughout the human gut, with a particularly studied role in early-life microbiome establishment.

Lactobacillus fermentum (species-level entry, no specific strain designation) is a heterofermentative lactic acid bacterium found in fermented foods and the human gastrointestinal tract.

Lacticaseibacillus rhamnosus GG (LGG) is one of the most extensively studied probiotic strains globally, though the papers linked to this strain entry focus primarily on encapsulation technology and formulation stability…

Lactobacillus brevis is a heterofermentative lactic acid bacterium widely distributed in fermented food environments.

Lacticaseibacillus rhamnosus Lcr35 (formerly Lactobacillus casei rhamnosus Lcr35) has been evaluated in several randomized controlled trials across distinct clinical contexts, including pediatric chronic constipation, va…

Lactobacillus crispatus M247 is a rod-shaped lactic acid bacterium characterized by its mucus-binding properties and production of antimicrobial compounds.

Ligilactobacillus salivarius (species-level entry, no specific strain designation) is an oral and intestinal lactic acid bacterium studied across several strains for immune modulation and respiratory health.

Bacillus coagulans is a spore-forming bacterium studied as a probiotic candidate, in part because its spores exhibit heat and acid stability, a property studied in relation to survival through food processing and gastric…

Lacticaseibacillus rhamnosus HN001 (formerly classified as Lactobacillus rhamnosus HN001) has been studied across in vitro, animal, and human randomized controlled trial settings.

Lactobacillus paragasseri is a lactic acid bacterium.
