Unraveling the oral microbiome's role in Alzheimer's disease: From pathophysiology to therapeutic potential

Alzheimer's &Dementia, Volume 21, Issue 12, December 2025.
Abstract Oral dysbiosis contributes to Alzheimer's disease (AD) by promoting neuroinflammation. Pathobionts such as Porphyromonas gingivalis, Treponema denticola, and Fusobacterium nucleatum release virulence factors that induce amyloid beta aggregation and tau hyperphosphorylation, while the loss of commensals like Streptococcus salivarius and ...

Effects of altitude on the gut microbiome and metabolomics of Sanhe heifers

Frontiers in Microbiology, 2023
IntroductionExtreme environments at high altitudes pose a significant physiological challenge to animals. We evaluated the gut microbiome and fecal metabolism in Sanhe heifers from different altitudes.MethodsTwenty Sanhe heifers (body weight: 334.82 ± 13.

Species‐level exploration of the gut microbiome in the leaf‐eating Presbytis monkeys reflected the effects of anthropogenic activity and specialized dietary niches: Conservation on the fourth biodiversity level

iMetaOmics, Volume 2, Issue 4, December 2025.
This study integrates full‐length 16S rRNA and deep metagenomic sequencing to explore species‐level gut microbial composition and function in two endangered leaf‐eating langur species—white‐headed langurs and François' langurs—across gradients of human disturbance.

Ruminal Planktonic, Weakly, and Tightly Feed-Adhered Bacterial Community as Affected by Two Trichoderma reesei Enzyme Preparations Fed to Lactating Cattle

Applied Microbiology
This study evaluates the effects of two Trichoderma reesei exogenous fibrolytic enzyme (EFE) preparations on the taxonomic profile, diversity, relative abundance, and population shifts of three ruminal bacteria fractions of lactating cows: free-floating (

Microbiota and Quality Indexes of Commercial Sauerkraut and Fermented Cucumbers

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Secundilactobacillus and Levilactobacillus were found to be significantly correlated with the content of cadaverine and histamine in the sauerkraut and fermented cucumbers. The high level of biogenic amines in the tested market samples indicates the need to monitor them as an indicator of the hygienic condition of fermented products.

Differential Assembly of Core and Non‐Core Host‐Microbe Network Structures Along a Land‐Use Change Gradient

Ecology Letters, Volume 28, Issue 11, November 2025.
Microbial communities affect host function, yet their assembly under environmental change remains unclear. Studying wild rats across a land‐use gradient, we found that non‐core microbes formed fragmented networks shaped mainly by heterogeneous selection, reflecting environmental filtering, while core microbes formed less modular networks driven ...

A mixture of quebracho and chestnut tannins drives butyrate-producing bacteria populations shift in the gut microbiota of weaned piglets.

PLoS ONE, 2021
Weaning is a critical period for piglets, in which unbalanced gut microbiota and/or pathogen colonisation can contribute to diseases that interfere with animal performance.

Food or family? How gut microbes respond to diet and phylogeny in two deer species

Ecosphere, Volume 16, Issue 10, October 2025.
Abstract Vertebrate herbivores require symbiotic gastrointestinal (GI) microbes to extract energy and nutrients from fibrous and sometimes toxic plant diets. Because GI microbes vary in their relative abundance, function, and degree of specialization, the microbial community depends on both the characteristics of plants consumed and the anatomical ...

Evaluation of Phaseolus vulgaris lec‐ lpa as Alternative Protein Source on Growth Performances, Health Status, Faecal Minerals and Gut Microbiota in Weaned Piglet's Diet

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
Partial replacement of soybean meal with an innovative Phaseolus vulgaris genotype with low lectin and phytic acid content was evaluated in weaned pigs’ diet. Although piglets fed the bean‐based diet showed reduced growth performance, their health status was preserved, registering lower faecal mineral excretion, suggesting reduced environmental ...

Differential response of digesta- and mucosa-associated intestinal microbiota to dietary insect meal during the seawater phase of Atlantic salmon

Animal Microbiome, 2021
Background Intestinal digesta is commonly used for studying responses of microbiota to dietary shifts, yet evidence is accumulating that it represents an incomplete view of the intestinal microbiota.
