Adhesion‐Enhanced Engineered Probiotic for Prolonged Intestinal Retention and Calprotectin‐Responsive IBD Therapy

Advanced Science, EarlyView.
An intelligent engineered probiotic platform is developed for the precision management of inflammatory bowel disease. By integrating surface‐displayed adhesins with an inflammation‐responsive CAT‐SOD‐GPx tripartite fusion system and mucosal repair factors, this programmable system achieves prolonged intestinal retention and multi‐pronged therapy.

Microbial‐Metabolite Signatures Are Associated With Glucocorticoid Responsiveness in Chronic Rhinosinusitis With Nasal Polyps

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) exhibit heterogeneous responses to oral glucocorticoids (GCs), but the biological basis of this variability remains unclear. Objective To identify gut microbiome‒plasma metabolomic signatures associated with GC responsiveness in CRSwNP patients and to compare their ...

PIGMENT PRODUCTION IN BACTEROIDES [PDF]

Journal of Medical Microbiology, 1969
Summary Chromogenesis by three members of the genus Bacteroides was studied. The species investigated were: Bacteroides melaninogenicus, B. fragilis and B. necrophorus. All were capable of pigment production, but each species required a different set of factors for chromogenesis. All needed cysteine and ferrous sulphate.

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Selenomethionine Regulates the Arachidonic Acid Metabolism‐Ferroptosis‐Inflammation Axis to Ameliorate Colitis

Animal Research and One Health, EarlyView.
Selenomethionine can ameliorate arachidonic acid‐induced colonic injury through synergistic mechanisms, including alleviating inflammatory responses, improving barrier integrity, enhancing antioxidant capacity by upregulating selenoprotein expression, selectively regulating AA metabolism to reduce pro‐inflammatory oxylipins and promote the production ...

SYNERGISTIC HEMOLYSIS IN “NON-HEMOLYTIC” BACTEROIDES SPECIES [PDF]

, 2020
Bacteroides is a genus of anaerobic bacteria that are often found in high abundance in the human colon. They have a complex relationship with their human host, conferring health benefits as members of the gut microbiota but also acting as opportunistic ...

Longitudinal Modulation of the Gut Microbiome and Growth Performance by Phytochemicals as Antibiotic Alternatives in Swine Production

Animal Research and One Health, EarlyView.
We conducted a longitudinal trial across nursery, growing, and finishing phases, showing that phytochemical supplementation as a potential antibiotic alternative reduced potential pathogens and promoted beneficial Lactobacillus amylovorus in the nursery phase, and enriched amino acid and carbohydrate metabolism pathways (prediction) during finishing ...

Interaction of Bacteroides fragilis and Bacteroides thetaiotaomicron with the kallikrein-kinin system

, 2011
Many bacterial pathogens interfere with the contact system (kallikrein kinin system) in human plasma. Activation of this system has two consequences: cleavage of high-molecular-mass kininogen (HK) resulting in release of the potent proinflammatory ...

Antimicrobial susceptibility of relatively infrequent isolates of the Bacteroides fragilis group: Bacteroides uniformis, bacteroides caccae, and Bacteroides eggerthii

Current Therapeutic Research, 1993
Abstract Using a broth microdilution method, clinical isolates of Bacteroides caccae (10 strains), Bacteroides eggerthii (1 strain), and Bacteroides uniformis (25 strains) were tested to determine their susceptibility to various beta-lactam agents, clindamycin, and metronidazole. All strains were beta-lactamase producers. Strains of B uniformis
