Stool transplants are exactly what they voice like : moving shit from a healthy mortal into a sick person , perhaps via a contraceptive pill or an clyster . I bring this up because most multitude grovel at the idea — but they ’re a treatment proven in effect for some antibiotic - repellent infections triggered by the Clostridium difficile , or C. diff bacterium , whichkilltens of K of Americans per year . A vulgar sweetener may be worsen these C. diff infections .
Two distantly connect epidemic strains of C. diff , call RT027 and RT078 , have emerge in the past 20 years in North America . Both have evolved enhanced power to infect and damage us , but scientists do n’t recognise why . Now , a team of researchers reckon that the introduction of a now common sugar additive into our diets , called trehalose , may be creditworthy for the increase virulence .
“ On the basis of [ our ] observations , we propose that the widespread adoption and use of the disaccharide trehalose in the human dieting has played a important purpose in the emergence of these epidemic and hypervirulent strains , ” the authors write in a newspaper write yesterday in the journal Nature .
Trehalose is a sugar that has been considered useful by the food industry thanks to its ability to withstand Lucy in the sky with diamonds and high heating plant . It was pretty expensive before 2000 , but a new method made it much easier to produce from amylum . It was yield a “ in the main pick out as safe ” status by the U.S. Food and Drug Administration in 2000 , according to the paper . It is now wide used in nation around the public , in solid food like alimentary paste , methamphetamine hydrochloride cream , and even ground kick .
Both C. diff strains were already around , but increasingly grave cases have been report since 2000 , grant toone paper . So the team of researchers from the U.S. , the Netherlands and the UK exposed the strains to trehalose , sequenced them , and even infect mouse with one of them .
Not only did the trehalose cause these two strains to develop faster than in other strains , but feed trehalose to black eye with the RT027 striving ( whose gut bacteria makeup had been alter to take care like a that of a homo ) killed them faster than the mice who did n’t eat trehalose . “ Combined , these results show that metabolism of dietary trehalose can give to disease severity of RT027 C. difficile strains , ” the authors spell .
It turn out that the two strain use trehalose in different way . RT027 has a modified protein that provide it to brook even diminutive amounts of trehalose . The RT078 instead has an additional four genes that give up it to better metabolise trehalose .
Obviously this is just a shiner field and test done in a lab — humans are not the same as mouse and the veridical world is not a laboratory . Jimmy Ballard from the University of Oklahoma point out that there are “ several avenues for further research ” in aNature commentary . C. diff infection take place in the human Aspinwall , but the body might break down trehalose before it reaches the Aspinwall . He noted that the authors of this paper tested fluid from the little gut .
The source do put forth further evidence that trehalose has something to do with the increasing rigour of C. diff infection , mainly surrounding the timing and acceptation of trehalose in the human diet compared to C. diff spreading and deterioration . And Ballard still found the results compelling . He write : “ the circumstantial and experimental grounds points to trehalose as an unexpected perpetrator . ”
