Poop may hold the arcanum to preserving spring chicken — at least for some fish .
In a recent subject field , scientist discovered that one-time fish hold up longer when they feed on microbes from young Pisces the Fishes ’s stool . Their determination suggest that themicrobiome — communities of single - celled organisms such as bacteria , fungus kingdom and viruses — plays a role in the aging process .
In their cogitation , the scientist examined turquoise killifish ( Nothobranchius furzeri ) , a craniate with one of the shortest life span on Earth . Killifishreach sexual maturity at 3 week old , and exit after only a few months of life story . As these Pisces the Fishes eld , their gut bacteria become less various , the researchers note . To test whether increasing microbiome diverseness might affect the aging process , the scientist enclose the intestine bacteria of young Pisces the Fishes to the older fish .

Middle - old age , 9.5 - calendar week - old killifish were presented with the gut contents of 6 - week - old killifish , lead author Dario Valenzano , a geneticist at the Max Planck Institute for Biology of Ageing in Germany , distinguish Nature . Though killifish do n’t eat feces , the older fish ingested microbes when they pick at at the fecal material to see if it was intellectual nourishment , Valenzano say .
" Recolonizing the catgut of in-between - geezerhood individuals with bacteria from vernal donors resulted in life twain telephone extension and delay behavioral decline , " the researcherswrote in the survey . " This intervention forestall the decrement in microbial diversity consort with server ageing and sustain a untested - like catgut bacterial community of interests . "
The older Pisces that consume the microbe from the new Pisces had a unlike bacterial make-up after doing so , according to the researchers . And at 16 weeks one-time , these " elderly " fish that received jr. microbe still hadgut microbiomessimilar to those of 6 - week - one-time killifish , the researchers said .
hold a younger microbiome also helped the older fish live longer : The fish that consumed the microbes from younger fish live 41 percent longer , on average , compared with the fish that did not encounter the young bug , harmonize to the investigator . The old fish were also more active , just like younger Pisces , the researchers regain .
" Our finding demonstrate that the natural microbic gut residential area of youthful someone can causally induce long - lasting beneficial systemic effects that lead to life span prolongation in a vertebrate model , " the researchers concluded in the cogitation .
Though the finding showed the impact of youthful microbes , it ’s unclear how , precisely , these microbes influence the fish ’s life distich , Valenzano told Nature . The researcher are bear on their experiments , now lick with fruit tent-fly , to better understand how themicrobiome is connect to aging .
Details of the study were publish on-line April 6 onbioRxiv , a preprint site for biology inquiry that has not yet been peer - reviewed .
