Engineering Human Donor Derived Germinal Center‐Like Organoids (GCLOs) for Studying Immune Response to Vaccination

Advanced Science, EarlyView.
We bioengineered a new approach methodology of generating Germinal Center Organoids that self‐organize from human blood‐derived immune cells. These immune organoids reproduce key features of humoral immunity, IgG production, and plasmablast emergence.

Evaluation of a Product Intended for Microbiological Control in Animal Production, and Its Combination With Halquinol

Animal Research and One Health, EarlyView.
Activo Liquid and Halquinol inhibit Salmonella and Escherichia coli in culture media. Activo Liquid exhibits bactericidal action, whereas HA is bacteriostatic, and their combination results in positive or indifferent interactions. This combination effectively inhibits E. coli throughout digestion simulation, thus reducing the required concentrations of

Blood Immunopathology of Tuberculosis Patients Disrupts Monocyte-Dependent T-Cell Activation and Cytokine Expression. [PDF]

Immunology
TB serum selectively disrupts monocyte‐dependent PHA T cell activation and cytokines associated with proliferation while preserving SEB T cell and Pam3/PHA monocyte cytokine responses. ABSTRACT Pulmonary tuberculosis in humans is characterised by features of immunopathology, which influence both antimycobacterial therapy and the long‐term prognosis. In

Effects of Dietary Mannan Oligosaccharides on Growth, Disease Resistance, and Gut Microbiota in Zebrafish

Animal Research and One Health, EarlyView.
Supplementation with mannan oligosaccharides (MOS) enhances growth, disease resistance, antioxidant capacity, and gut microbiota diversity while suppressing inflammation, apoptosis, and strengthening intestinal barrier integrity in zebrafish challenged with LPS or DSS.

Microbial Hydrolysates as Amino Acid Source in Cell Culture Media for Cellular Agriculture

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The high cost of cultivation media remains one of the barriers to the commercialization of cultivated meat. Current serum‐free media reduce reliance on fetal bovine serum but only achieve modest cost savings. Especially at larger scales (> 20 m3), pharmaceutical‐grade amino acids and recombinant proteins remain major cost drivers.

Biosafe Control of Staphylococcal Enterotoxins Production in Shelf-Stable Bacon

Fermentation
This study proposed a biosafe strategy to prevent staphylococcal enterotoxin production in cooked bacon, particularly in microenvironments at the product–package interface that may favor toxinogenesis. Challenge tests were conducted on bacon samples with

Upcycling Pomegranate Peel Into Functional Yoghurt: Chemical Profile, Antioxidant Capacity, and Anti–Staphylococcus aureus Activity

Food Safety and Health, EarlyView.
Pomegranate peel extract enhanced the nutritional, physicochemical, and microbiological qualities of yoghurt. It is a rich source of polyphenolic compounds that eliminates Staphylococcus aureus in yoghurt at 0.1% and 0.3% concentrations without altering its pH value. ABSTRACT The use of natural additives, particularly pomegranate peel extract (PPE), to

Non-structural Enterotoxin (NSP4) Gene based Molecular Characterization of Caprine and Ovine Rotavirus A, India

, 2020
Rotavirus A (RVA) causes viral gastroenteritis in humans and animals, including calves, piglets, and foals. The current study reports the genetic characterization of the full-length enterotoxin gene, NSP4, from caprine and ovine species.
