Abstract

The aim of the present study was to determine whether there is the mechanistic connection between antibacterial-dependent gut microbiota disturbance and anxiety. First, exposure of mice to ampicillin caused anxiety and colitis and increased the population of Proteobacteria, particularly Klebsiella oxytoca, in gut microbiota and fecal and blood lipopolysaccharide levels, while decreasing lactobacilli population including Lactobacillus reuteri. Next, treatments with fecal microbiota of ampicillin-treated mouse (FAP), K. oxytoca, or lipopolysaccharide isolated from K. oxytoca (KL) induced anxiety and colitis in mice and increased blood corticosterone, IL-6, and lipopolysaccharide levels. Moreover, these treatments also increased the recruitment of microglia (Iba1+), monocytes (CD11b+/CD45+), and dendritic cells (CD11b+/CD11c+) to the hippocampus, as well as the population of apoptotic neuron cells (caspase-3+/NeuN+) in the brain. Furthermore, ampicillin, K. oxytoca, and KL induced NF-κB activation and IL-1β and TNF-α expression in the colon and brain as well as increased gut membrane permeability. Finally, oral administration of L. reuteri alleviated ampicillin-induced anxiety and colitis. These results suggest that ampicillin exposure can cause anxiety through neuro-inflammation which can be induced by monocyte/macrophage-activated gastrointestinal inflammation and elevated Proteobacteria population including K. oxytoca, while treatment with lactobacilli suppresses it.

  • Antibiotic-induced perturbations in gut microbial diversity influence neuroinflammation with altered microglial morphology.

    “antibiotic-induced perturbations in gut microbial diversity influence neuroinflammation with altered microglial morphology (105–107).”

    From The Role of Short-Chain Fatty Acids From Gut Microbiota in Gut-Brain Communication (2020) · cites this paper as [107]

    The Results report that ampicillin changed gut microbial composition, and the Discussion links ampicillin-associated changes to microglial recruitment and neuroinflammation in mice (page numbers unavailable). The paper does not report altered microglial morphology; it measures or describes microglial cells and their recruitment instead. (LLM, conf=0.87)

  • Perturbations in microbial diversity due to antimicrobials influence pro-inflammatory cytokine secretion in the CNS and alter microglial morphology.

    “Perturbations in microbial diversity, secondary to antimicrobials, have been shown to influence pro-inflammatory cytokine secretion in the CNS and alter microglial morphology (268–270).”

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.
