Sounds like it won't belong before cultures of A. muciniphila start showing up on shelves.
What has been learned about the human gut in the last 20 years is really amazing. Our gut microbiota contains tens of trillions of microorganisms, including at least 1,000 different species of known bacteria with more than 3 million genes (150 times more than human genes), but only 150 to 170 predominate in any given individual. Microbiota can, in total, weigh up to 4.5 pounds. One third of our gut microbiota is common to most people, while two thirds are specific to each one of us. In other words, the microbiota in your intestine is like an individual identity card.
So Akkermansia muciniphila in our guts weighs 0.7 ounces to 3.5 ounces in total and we didn't know about it until 2004!
In a similar vein,Helicobacter pylori the a bacterium that colonizes human stomach and causes of chronic superficial gastritis, chronic active gastritis, peptic ulcer disease and gastric adenocarcinoma was first identified in 1985. H. pylori is now recognized causes more than 90% of duodenal ulcers and up to 80% of gastric ulcers. I had H. pylori for years and my doctor could not figure out my stomach symptoms. Finally, after doing my own research, I got after my doctor to test for it and it came back positive. One regimen of antibiotics eradicated it in early 2018 and I feel so much better than I have in years.
They're really, really small................
