Odoribacteraceae

 

“In people over the age of 100, an enrichment

in a distinct set of gut microbes generate

unique bile acids.”

Professor Kenya Honda

 

New research on the gut microbiome of old folks in Japan was reported in the latest issue of Nature Research. The scientists analyzed the gut bacteria of more than 300 adults in Japan, including 160 over 100 years-old, 112 between 85 and 89, and 47 under 55 years-old. Principal investigator Honda and colleagues found that bacterial isolates in fecal samples from centenarians were often enriched with microbes capable of synthesizing potent bile acids that were not present in the younger groups. Odoribacteraceae strains in particular came out as star producers of isoallo-lithocholic acid (LCA). LCA is a potent antimicrobial against gram-positive, multidrug-resistant strains such as Clostridioides difficile and Enterococcus faecium.

The conclusion of this study, per Prof. Honda: “There are centenarian-specific members of the gut microbiota which, rather than representing a mere consequence of aging, might actively contribute to resistance against pathogenic infection and other environmental stressors.” 

There are a host of responses to this study.  Many readers had their own theories of aging well.  One young lady declared that skinny was the perfect answer, and her daily intake, delivered in anorectic detail, made me cringe.  Another woman, struggling with C. diff unresponsive to various medications, took matters into her own hands.  She announced to her daughter that she needed a stool sample from her. The daughter, first appalled, then complied. The sample was inserted into one end or another (we got no info over which), and mom felt increasingly normal in a gut sort of way within four days!

I’d like to get ahold of a distinct set of those Odori-bugs, but alas, no search on Amazon or Google offered hope for bottles of such supplements just yet.
