Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

open access: yesInsect Conservation and Diversity, EarlyView.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Immobilized Dehydrogenases for the Biosynthesis of Phenylacetic Acids

open access: yesApplied Sciences
Two phenylacetaldehyde dehydrogenases, originating from Escherichia coli K-12 (FeaB-K-12) and Sphingopyxis fribergensis Kp5.2 (FeaB-Kp5.2), were immobilized on powdery silica carrier with various functionalization.

A Comparison of Endodontic Microbiomes Associated With Symptomatic and Asymptomatic Apical Periodontitis by Next‐Generation Sequencing

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim This cross‐sectional study aimed to compare the endodontic microbiome assessed from root canals of teeth associated with either symptomatic or asymptomatic apical periodontitis and analysed by 16S rDNA gene sequencing. Methodology 60 teeth presenting clinical and radiographic signs of symptomatic or asymptomatic apical periodontitis (n ...

Association Between the Root Canal Microbiome and Apical Lesion Size: An Observational Shotgun Metagenomic Study

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim The aim was to characterize the taxonomic and functional composition of the microbiome involved in primary endodontic infections and to evaluate their association with the periapical lesion size using shotgun metagenomic sequencing. Methodology Samples from primary root canal infections diagnosed with apical periodontitis were analysed ...

Can Artificial Intelligence Be Utilised to Develop Point‐of‐Care Endodontic Microbiological Technologies?

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Background Primary or persistent endodontic disease is caused by microbial biofilms that irritate the pulp and periapical tissues. Extensive microbiological analyses of these biofilms and their constituent pathogens have revealed their diversity and complexity.

Systemic Antibiotics in the Surgical Treatment of Peri‐Implantitis: Impact on the Salivary Microbiome

open access: yesJournal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To exploratorily compare the shifts in the salivary microbiome composition after administration of two combined systemic antibiotic regimens used in the surgical treatment of peri‐implantitis. Materials and Methods A subset of 27 patients treated surgically for peri‐implantitis with an adjunctive 7‐day course of systemic antibiotics were ...

Synergistic Benefits of Butyric Acid and Resistant Potato Starch on Growth and Gut Health in Weaned Pigs

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Newly‐weaned piglets face challenges such as reduced feed intake, impaired gut function, and susceptibility to post‐weaning diarrhoea, increasing the need for dietary strategies that support gut health and growth. This study investigated the effects of dietary supplementation with butyric acid (BA), resistant potato starch (PS), and their ...

L‐Glutamine Plus L‐Glutamic Acid Enhances Antioxidant Status and Ammonia Toxicity Resilience, Upregulates Interleukin IL‐10 Gene, and Improves Gut Microbiota and Survival in Juvenile Nile Tilapia

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Glutamine (Gln) and glutamic acid (Glu) are the most abundant free amino acids (AAs) in the fish body. Although classified as non‐essential AAs, their supplementation can be a strategy to optimize the growth performance and health of fish.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...
