Proportion in the Gut

I changed "large portion" to "small portion". More recent clinical microbiology places the class Clostridia as ~95% of the Firmicutes found in the human intestine (Eckburg, PB et al., Science, vol. 308, 2005). Lactobaccillus belongs to the Bacilli class which only represents ~0.2% of all Firmicutes found in the gut. Moreover, Firmicutes only represent ~70% of the gut flora which further lowers the percentage of Lactobacillus.

Major taxonomy change in the genus Lactobacillus (April 2020)

The genus of Lactobacillus has been been reclassified in to 25 genera. Therefore, the nomenclature for most articles with (former) Lactobacillus species is now incorrect.

Correcting this is a big task, and probably requires more Wiki experience than I have.

Weirdly specific suggestion of European vaginal microbiota as somehow unique and ethnically inherent, intrinsic

In the introduction, "In women of European ancestry, Lactobacillus species are normally a major part of the vaginal microbiota," in and in the vaginal microbiota segment

in around 70% of women, a Lactobacillus species is dominant, although that has been found to vary between American women of European origin and those of African origin, the latter group tending to have more diverse vaginal microbiota.

The sample was specifically American women from Virginia. Women of all groups have predominant Lactobacillus species in their vaginal microbiotas, even the same species of Lactobacillus makes the bulk of the microbiota, with something like a remaining 25-20% being more varied. Quoting another study:

The types of vaginal communities found in Japanese women were similar to those of Black and White women. As with White and Black women, most vaginal communities were dominated by lactobacilli, and only four species of Lactobacillus (Lactobacillus iners, Lactobacillus crispatus, Lactobacillus jensenii, and Lactobacillus gasseri) were commonly found. Communities dominated by multiple species of lactobacilli were common in Japanese and White women, but rare in Black women. The incidence, in Japanese women, of vaginal communities with several non-Lactobacillus species at moderately high frequencies was intermediate between Black women and White women."

Going to look at this, partly because I need to evaluate where content goes after the 2020 split. My current, 5-minute impression is that the existing PMID 22746335 citation is not at fault here. It's a review that cites equally the Japanese paper and the American stuff. It also does NOT suggest that with a domination by a single species being correlated with general welfare and good outcomes in pregnancy, but maybe one of its references does. --Artoria2e5 🌉 03:39, 3 December 2023 (UTC)

I can now report that this section, in fact, does not need to be moved as a result of Zheng. Still gotta think about how to fix it. Let me first forget about this xkcd comic. --Artoria2e5 🌉 05:50, 3 December 2023 (UTC)
