Abstract

Prolonged lack of enteral feeding has a negative impact on gut physiology, potentially via microbiota modulation. The aims were to investigate the impact of fasting and post-prandial changes in canine jejunal microbiota. To study post-prandial effects, jejunal brushings were analyzed in 8 healthy fistulated dogs 15 min before feeding (baseline) and hourly for 8 h after feeding. To study effects of withholding food (WF), daily samples were collected for 15 days from 5 dogs. The first 5 days (PRE) dogs were fed regular diet. Food was withheld the next 5 days (days 6-10). For days 11-15 (POST), the original diet was reintroduced. Microbiota was characterized via denaturing gradient gel electrophoresis and 454-pyrosequencing of 16S rRNA genes. In the post-prandial study, no changes in microbiome structure were seen after feeding (ANOSIM, P = 0.28), but Betaproteobacteria (P = 0.04) and Bacteroidales decreased compared to baseline. Species richness decreased by 300 min (P = 0.04). During WF, microbiota structure differed from PRE and POST period (P = 0.001). During WF, species richness did not vary over time (P = 0.69). In conclusion, a prolonged period of food withholding results in altered jejunal microbiota. How these changes affect the microbiota metabolism warrants further studies.

  • Time-restricted feeding in mice and repeated prolonged cycles of feeding and withholding food in dogs cause a change in the overall gut microbiome that appears driven by changes in the abundance of species that differ by their preferred fermentable substrates.

    “Time-restricted feeding in mice [79] and repeated prolonged cycles of feeding and withholding food in dogs [80] have all been shown to cause a change in the overall gut microbiome that appears to be driven by changes in the abundance of species that differ by their preferred fermentable substrates (e.g., host-vs. diet-derived glycans).”

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.
