I must admit that I have never thought about sourdough that much ... I am impressed.
The German word is likewise, btw, you can still somewhat sense the common linguistic history of both words: Sauerteig. Which does look different, but gets more obvious phonetically:
ˈsaʊədəʊ
ˈzaʊ̯ɐˌtaɪ̯k

dough going back to Middle English dagh, where the connection is more visible.
Both going back to proto-germanic daigaz (ˈdɑi̯.ɣɑz).

Some Animals Have No Microbiome. Here’s What That Tells Us. (04/2020, quantamagazine.org)

To stay healthy, humans and some other animals rely on a complex community of bacteria in their guts. But research is starting to show that those partnerships might be more the exception than the rule.

“Every organism that exists has three and a half billion years of evolutionary history behind it, many millions or tens or hundreds of millions of which are not shared with organisms that we use as models,” Sanders said. Scientists’ emerging awareness of the diverse relationships that animals share with microbes “should make us really cautious about drawing inferences using fruit flies as models for gut microbiome importance or interactions, because fruit flies might be operating from a very different fundamental starting point compared to humans. It’s the same thing with mice.”

An apple contains about 100 million bacteria—a more diverse range than any dietary supplement.

Eat a “balanced” diet, full of fresh fruits and vegetables, nuts and seeds, et cetera. If you do all that, except for specific cases, the average person shouldn’t need supplemental microbes.

Bacteriophage therapy: a potential solution for the antibiotic resistance crisis
J Infect Dev Ctries 2014; 8(2):129-136  doi:10.3855/jidc. 3573)


Abstract
The  emergence of multiple drug-resistant bacteria has  prompted interest in alternatives to conventional antimicrobials.  One of the possible replacement options for antibiotics is the use of bacteriophages as antimicrobial agents. Phage therapy  is an important alternative to antibiotics in the current era of drug-resistant pathogens. Bacteriophages have played an important role in the expansion of molecular biology and have been used as antibacterial agents since 1966. In this review,  we describe a brief history of bacteriophages and clinical studies on their use in bacterial disease prophylaxis and therapy. We discuss the advantages and disadvantages of bacteriophages as therapeutic agents in this regard.

Yes, it is not really an one-family format. :-)
In Italy, at least in my region, this solution You can find on a buffet for parties. Typically the catering service breaks a half cheese form into many handy pieces.
The cheese serves as apéritif and is often combined with a glass of Prosecco. Or it serves at the end of the meal to "close the stomach" with a Grappa.

Jonathan Bailor has been a big part of my health and nutrition education over the past 8 years. He has a new series out about diabesity. It is a program he is selling, but 8 hours of video from it are free to watch this weekend. Having only watched the first half hour (and the weekend would probably be over if I waited until I finished to post this), I can't really give you a review of it, but I have always been impressed with his research. He is not a medical researcher, but he researches the research. His mission is to take the information being learned by actual researchers and make it understandable to the rest of us. So, if you are frozen in this weekend and want to learn more about diabesity for yourself or someone you know, have a look.

Matjes eaten "the Dutch way"

Is fermentation really so effortless? The short answer is yes. Many recipes will call for two things: water and salt. At just a 1:50 ratio (2%) of salt to food, you can create an environment undesireable for all the bad bacteria and encourage all the good ones. Sauerkraut, kimchi, fish sauce, sriracha, and kosher dill pickles—are all made according to this principle.

Optimum nutrition for kidney stone disease (2018)

  
For those who are interested in this specific topic: I tried to summarize the state of the art 2018 about the argoment.
In any case, the most important thing, regardless of the type of  renal stone, is good hydration, day and night. Very interesting is the recent approach of a microbiology therapy, recolonizing the intestine with Oxalobacter formigenes.

Image/photo

Abstract
We summarize the data regarding the associations of individual dietary components with kidney stones and the effects on 24-hour urinary profiles. The therapeutic recommendations for stone prevention that result from these studies are applied where possible to stones of specific composition. Idiopathic calcium oxalate stone-formers are advised to reduce ingestion of animal protein, oxalate, and sodium while maintaining intake of 800 to 1200 mg of calcium and increasing consumption of citrate and potassium. There are few data regarding dietary therapy of calcium phosphate stones. Whether the inhibitory effect of citrate sufficiently counteracts increasing urine pH to justify more intake of potassium and citrate is not clear. Reduction of sodium intake to decrease urinary calcium excretion would also be expected to decrease calcium phosphate stone recurrence. Conversely, the most important urine variable in the causation of uric acid stones is low urine pH, linked to insulin resistance as a component of obesity and the metabolic syndrome. The mainstay of therapy is weight loss and urinary alkalinization provided by a more vegetarian diet. Reduction in animal protein intake will reduce purine ingestion and uric acid excretion. For cystine stones, restriction of animal protein is associated with reduction in intake of the cystine precursor methionine as well as cystine. Reduction of urine sodium results in less urine cystine. Ingestion of vegetables high in organic anion content, such as citrate and malate, should be associated with higher urine pH and fewer stones because the amino acid cystine is soluble in more alkaline urine. Because of their infectious origin, diet has no definitive role for struvite stones except for avoiding urinary alkalinization, which may worsen their development.

Abstract
Most kidney stones are composed primarily of calcium oxalate. Oxalobacter formigenes is a Gram-negative, anaerobic bacterium that metabolizes oxalate in the intestinal tract and is present in a large proportion of the normal adult population. It was hypothesized that the absence of O. formigenes could lead to increased colonic absorption of oxalate, and the subsequent increase in urinary oxalate could favor the development of stones. To test this hypothesis, a case-control study involving 247 adult patients with recurrent calcium oxalate stones and 259 age-, gender-, and region-matched control subjects was performed. The prevalence of O. formigenes, determined by stool culture, was 17% among case patients and 38% among control subjects; on the basis of multivariate analysis controlling demographic factors, dietary oxalate, and antibiotic use, the odds ratio for colonization was 0.3 (95% confidence interval 0.2 to 0.5). The inverse association was consistently present within strata of age, gender, race/ethnicity, region, and antibiotic use. Among the subset of participants who completed a 24-h urine collection, the risk for kidney stones was directly proportional to urinary oxalate, but when urinary factors were included in the multivariable model, the odds ratio for O. formigenes remained 0.3 (95% confidence interval 0.1 to 0.7). Surprisingly, median urinary oxalate excretion did not differ with the presence or absence of O. formigenes colonization. In conclusion, these results suggest that colonization with O. formigenes is associated with a 70% reduction in the risk for being a recurrent calcium oxalate stone former.

@Manuel  You are right.
I believe that there are many factors that contribute to the formation of kidney stones. I guess it's also the very hot weather for several months a year in your area that predisposes to a latent daily dehydration of people leading to concentrated urine. Gradually, combined with other individual factors, this is the terrain predisposing for the formation of the first crystals that then make stone.
For those at risk the key message is: People drink, hydrate well, day and night (drink before going to bed, even at the cost of getting up at night), thus diluting the urine. If stones have already been made, all the other measures (first and foremost nutritional) mentioned in the above-mentioned sources are useful.

Well, to know it!  :-)


Abstract
We critically revisit the ″common knowledge″ that bacteria outnumber human cells by a ratio of at least 10:1 in the human body. We found the total number of bacteria in the ″reference man″ to be 3.9·1013, with an uncertainty (SEM) of 25%, and a variation over the population (CV) of 52%. For human cells we identify the dominant role of the hematopoietic lineage to the total count of body cells (≈90%), and revise past estimates to reach a total of 3.0·1013 human cells in the 70 kg ″reference man″ with 2% uncertainty and 14% CV. Our analysis updates the widely-cited 10:1 ratio, showing that the number of bacteria in our bodies is actually of the same order as the number of human cells. Indeed, the numbers are similar enough that each defecation event may flip the ratio to favor human cells over bacteria.
