I’ve been discussing how the microbe, Lactobacillus reuteri, is ubiquitous in mammals and in people unexposed to antibiotics and different microbiome-disruptive elements similar to meals components, glyphosate, different prescribed drugs, and many others.
If we had been to look at the feces of squirrels, raccoons, or chickens, all of them have L reuteri. If we studied the feces of indigenous human populations in distant jungles of New Guinea or the Brazilian rainforest, additionally they all have L reuteri. A current fascinating examine of historic microbial DNA in southeastern Spain has recognized what’s believed to be fecal materials from Neanderthals who populated the area 45,000 to 60,000 years in the past—they usually had L reuteri. (Anthropologists have proof that Homo sapiens and this totally different species, Homo neanderthalensis, co-existed for tens of hundreds of years earlier than they grew to become extinct.)
Even Dr. Gerhard Reuter, who found this microbial species in human breast milk in 1962, had no drawback discovering it at first. Over the following 40 years of his microbiology profession in Germany, he had rising issue in recovering this microbe. And, certainly, subsequent analyses have demonstrated that this species has virtually disappeared from the trendy human microbiome.
The widespread lack of L reuteri ought to come as no shock, given its susceptibility to widespread antibiotics similar to ampicillin, amoxicillin, and others. Satirically, regardless of its susceptibility to antibiotics, it’s itself a producer of potent bacteriocins, pure peptide antibiotics efficient towards stool species similar to E coli, Klebsiella, and Campylobacter. L reuteri is such an efficient antimicrobial towards gastrointestinal pathogens that my microbiologist mates inform me that they often clear their fermentation vats with this species. However not solely is L reuteri a producer of at the very least 4 kinds of bacteriocins, it’s also distinctive in that it colonizes the higher gastrointestinal tract, exactly the place the battleground for SIBO happens. Might the widespread lack of L reuteri from trendy human microbiomes be one of many causes that small intestinal bacterial overgrowth,SIBO, has turn out to be epidemic, now afflicting at the very least 100 million People by my estimation? I feel it’s—restoring L reuteri might due to this fact be a part of the answer and the rationale why I embody this species in my recipe for “SIBO Yogurt” that, up to now, has eradicated SIBO, as detected by AIRE H2 breath testing, in 90% of people that have tried it. (See my Tremendous Intestine guide for the SIBO Yogurt recipe in the event you’d like to present this a strive earlier than resorting to antibiotics to eradicate SIBO.)
Animals have it, indigenous human populations have it, even Neanderthals had it, and it’s best to have it, too.
