Lactobacillus caccae sp. nov., a new bacterial species isolated from the
human gut microbiota
The increasingly wide knowledge of the microbiota, as well as its
continuous relation with several pathologies, favours the interest,
discovery and classification of all the bacteria that are part of it.
The isolation of strain P3519T is possible thanks to the application of
new strategies such as culturomics and taxono-genomics. Strain
Marseille-P3519T isolated from the fecal flora of a 25-year-old healthy
French woman was a Gram-positive anaerobic bacterium, non-motile and
non-spore-forming. The 16S rRNA gene sequence of Marseille-P3519 showed
98.57% of sequence similarity with Lactobacillus caviae MOZM2, the
closest species, phylogenetically. Its genome had 2,237,367 bp with
45.42 mol% of G+C content. These findings support that strain
Marseille-P3519 is a new member of the genus Lactobacillus for which the
name Lactobacillus caccae sp. nov., is proposed.
