Limosilactobacillus vaginalis is a lactic acid bacterium that is a normal, but infrequent part of the vaginal microbiome.

[1] The vaginal secretions of women suffering from trichomoniasis were examined for the presence of certain proposed Lactobacillus strains exhibiting mutualistic behavior with Trichomonas vaginalis, facilitating sustainment of infection.

[1] The new species L. vaginalis with type strain NCTC 12197 was proposed, and the description of its carbohydrate fermentation patterns as well as cellular fatty acid composition were provided.

[1] Further taxonomic investigations relying on 16S rRNA gene sequence analysis placed L. vaginalis in the L. reuteri phylogenetic group along with 14 other species, including L.

[1] These obligate heterofermentative lactobacilli produce both D and L isomers of lactic acid as the metabolic end-product of carbohydrate fermentation.
