Abstract

There is increasing evidence that the gut microbiota plays a major role in host health and disease. In this study, we examined whether perturbation of the maternal gut microbiota during pregnancy, induced by administration of non-absorbable antibiotics to pregnant dams, influences the behavior of offspring. Terminal restriction fragment length polymorphism analyses of fecal bacterial composition showed that the relative abundance of the bacterial order Lactobacillales was lower in offspring born from antibiotic-treated dams (20.7 ± 3.4%) than in control offspring (42.1 ± 6.2%) at P24, while the relative abundance of the bacterial family Clostridium subcluster XIVa was higher in offspring born from antibiotic-treated dams (34.2 ± 5.0%) than in control offspring (16.4 ± 3.3%). Offspring born from antibiotic-treated dams exhibited low locomotor activity in both familiar and novel environments, and preferred to explore in the peripheral area of an unfamiliar field at postnatal week 4. At postnatal weeks 7-8, no difference was observed in the level of locomotor activity between control offspring and offspring from antibiotic-treated dams, while the tendency for the offspring from antibiotic-treated dams to be less engaged in exploring the inside area was still observed. The behavioral phenotypes of the offspring from antibiotic-treated dams at postnatal week 4 could be rescued to a considerable extent through fostering of these offspring by normal dams from postnatal day 1. Although the detailed underlying mechanisms are not fully elucidated, the present results suggest that administration of non-absorbable antibiotics to pregnant dams to perturb the maternal gut microbiota during pregnancy leads to alterations in the behavior of their offspring.

  • Non-absorbable antibiotics such as vancomycin, neomycin, and bacitracin knockdown the microbiota in the gut while not entering systemic circulation, thereby avoiding potential systemic and CNS effects.

    “Non-absorbable antibiotics (i.e.vancomycin, neomycin, and bacitracin (Tochitani et al., 2016)) offer the advantage that they knockdown the microbiota in the gut while not entering systemic circulation, thereby avoiding any potential systemic and even central nervous system (CNS) effects”

    From The Microbiota-Gut-Brain Axis (2019) · cites this paper as Tochitani et al., 2016

    Materials and Methods (Animals and non-absorbable AB treatment; page unavailable) says non-absorbable antibiotics concentrate in the gastrointestinal tract, perturb gut microbiota, and have limited serum concentrations. Its treatment contains neomycin and bacitracin, but not vancomycin. The passage suggests minimal collateral effects; it does not establish that the drugs never enter systemic circulation or avoid all potential systemic and CNS effects. (LLM, conf=0.88)

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.
