Abstract

The gastrointestinal tracts of mammals are colonized by hundreds of microbial species that contribute to health, including colonization resistance against intestinal pathogens. Many antibiotics destroy intestinal microbial communities and increase susceptibility to intestinal pathogens. Among these, Clostridium difficile, a major cause of antibiotic-induced diarrhoea, greatly increases morbidity and mortality in hospitalized patients. Which intestinal bacteria provide resistance to C. difficile infection and their in vivo inhibitory mechanisms remain unclear. Here we correlate loss of specific bacterial taxa with development of infection, by treating mice with different antibiotics that result in distinct microbiota changes and lead to varied susceptibility to C. difficile. Mathematical modelling augmented by analyses of the microbiota of hospitalized patients identifies resistance-associated bacteria common to mice and humans. Using these platforms, we determine that Clostridium scindens, a bile acid 7α-dehydroxylating intestinal bacterium, is associated with resistance to C. difficile infection and, upon administration, enhances resistance to infection in a secondary bile acid dependent fashion. Using a workflow involving mouse models, clinical studies, metagenomic analyses, and mathematical modelling, we identify a probiotic candidate that corrects a clinically relevant microbiome deficiency. These findings have implications for the rational design of targeted antimicrobials as well as microbiome-based diagnostics and therapeutics for individuals at risk of C. difficile infection.

  • Certain secondary bile acids serve significant biological functions, including regulation of host metabolism, immunity, and resistance against intestinal pathogen expansion.

    “Nevertheless, it is noteworthy that certain secondary BAs serve significant biological functions, including the regulation of host metabolism, immunity, and resistance against intestinal pathogen expansion.21,360–364”
  • Previous studies have described that successful FMT treatment of recurrent infection by C. difficile relies on restoration of correct bile acid metabolism, and that antibiotic-induced microbiome depletion reduces the secondary bile acid pool.

    “Previous studies have described that successful FMT treatment of recurrent infection by C. difficile relies on restoration of correct bile acid metabolism 35,36 , and that antibioticinduced microbiome depletion reduces the secondary bile acid pool 37 .”
  • Bacillus thuringensis secretes thuricin CD, a bacteriocin with narrow-spectrum activity against gram-positive bacteria including C. difficile.

    “Bacillus thuringensis secretes a bacteriocin, thuricin CD, with narrow spectrum activity against gram positive bacteria including C. difficile; it is likely other members of the gut microbiota secrete similar antimicrobials.53”
  • Other members of the gut microbiota likely secrete antimicrobials similar to thuricin CD.

    “it is likely other members of the gut microbiota secrete similar antimicrobials.53”
  • C. scindens inhibits growth of C. difficile through generation of secondary bile acids deoxycholic acid and lithocholic acid.

    “the commensal bacterium C. scindens can inhibit growth of C. difficile through the generation of secondary bile acids deoxycholic acid (DCA) and lithocholic acid (LCA) [54].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
