Antibiotic Remodeling of the Gut Microbiota Impairs Host Resistance to Secondary Infection

iMetaMed, EarlyView.
Gut microbial dynamics induced by four antibiotics, revealed distinct taxonomic and functional shifts. Vancomycin‐perturbed bacteriomes were proven to promote pathogen resistance to antibiotic treatment. Metronidazole‐treated mice showed pronounced Salmonella translocation to hepatic tissue, and altered Enterococcus avium populations modulated host ...

Stratification of chronic rhinosinusitis with nasal polyps by distinct sinonasal microbial communities and their clinical and pathological correlations

iMetaOmics, EarlyView.
Chronic rhinosinusitis with nasal polyps (CRSwNP) is a heterogeneous inflammatory condition. Dysbiosis is commonly observed. This study identified distinct sinonasal microbial communities in CRSwNP patients and explored their clinical and pathological associations. Two distinct microbial communities were identified: community type 1 (CT1), dominated by

A review of the role of enterotoxigenic Bacteroides fragilis in the development of colorectal cancer

Basic & Clinical Cancer Research
Enterotoxigenic Bacteroides fragilis (ETBF) plays a significant role in the development and progression of colorectal cancer (CRC) through the production of Bacteroides fragilis toxin (BFT). This toxin activates Wnt, NF-κB, and STAT3 signaling pathways,

Probiotics‐derived postbiotics improve host metabolic syndrome by activating the adipocyte thermogenic signaling pathway in high‐fat diet‐fed mice

iMetaOmics, EarlyView.
This schematic illustrates how probiotics‐derived postbiotics (PLBK®1–5) combat high‐fat diet‐induced obesity. Postbiotics remodel gut microbiota, boosting beneficial metabolites. These metabolites activate adipocyte thermogenesis (Ucp1/AMPK pathway), resulting in reduced body weight, improved insulin sensitivity, and alleviated hepatic steatosis in ...

Colonisation of Newborn Piglets with a Mixture of Bacteroides Species Improves Their Gut Health and Performance

Microorganisms
Due to the low populations of Bacteroides sp. in the gut microbiota of sows compared to nursed piglets, sows may not represent an ideal source of Bacteroides sp. for newborn piglets. In this study, we therefore tested the effect of oral administration of

Beyond “you are what you eat”: Unlocking gut microbiota‐mediated biotransformation of dietary phytochemicals

iMetaOmics, EarlyView.
The “efficacy paradox” of phytochemicals, low bioavailability yet significant health benefits, is associated with gut microbiota, which biotransforms dietary precursors into bioactive metabolites, enabling systemic effects. Thus, health outcomes of diet depend not just on intake “the rainbow”, but on gut microbial metabolism, redefining “you are what ...

The mediating roles of gut microbiota in the associations of air pollution and meteorological factors with metabolic syndrome

iMetaOmics, EarlyView.
We characterized distinct gut microbial community clusters associated with metabolic syndrome (MetS) and identified key genera underlying these patterns. Health‐associated clusters were dominated by beneficial genera such as Bacteroides and Prevotella with known metabolic protective functions.

Changes in the gut microbiome during fasting‐induced molting and its effects on gut–liver function

iMetaOmics, EarlyView.
During fasting, harmful microbiota and metabolites rise, triggering intestinal injury and activation of the TGF‐β signaling pathway, which enhances intestinal stem cell proliferation. Concurrently, hepatic function declines, indicated by increased hepatic and serum bile acids and upregulation of the non‐classical bile acid synthesis pathway.

Microbial keystone taxa and metabolic signatures in centenarians regulate intestinal homeostasis during aging

iMeta, EarlyView.
Clostridium scindens and its metabolite indole‐3‐acetic acid (IAA) are identified as a keystone taxon and metabolic signature in centenarians. Clostridium scindens enhances microbial network stability and produces IAA via its own amidase (AMIE) and aldehyde dehydrogenase (ALDH), thus promoting intestinal homeostasis by activating the aryl hydrocarbon ...

Early gut microbial and metabolic dysregulation with subclinical cardiac alterations in a nonhuman primate model of Rett syndrome

iMeta, EarlyView.
Longitudinal multi‐omics profiling of a nonhuman primate Rett syndrome (RTT) model reveals early systemic alterations. RTT monkeys exhibited postnatal growth retardation, intestinal structural abnormalities, and low‐grade systemic inflammation. Gut microbiome analysis showed delayed microbial maturation and age‐discordant dysbiosis, including altered ...
