A genus-specific TaqMan real-time PCR assay for the rapid detection of Wallemia in bakery production environments

Abstract The xerophilic fungal genus Wallemia is an important cause of fungal contamination in bread manufacturing environments, but its detection by conventional culture-based methods is often difficult because of slow growth and competitive overgrowth by other fungi. Here, we r...

Sucralose Alters Gut Microbiota, Intestinal Metabolites, and Epithelial Serotonergic Responses to Visceral Stimulation in Mice Exposed to Chronic Restraint Stress

Background/Objectives: Dietary modifiers of the gut ecosystem may influence intestinal and host responses associated with psychological stress. However, it remains unclear whether sucralose, a widely consumed non-nutritive sweetener, alters host–microbiota interactions following...

Chronic oral exposure to didecyldimethylammonium chloride induces region-specific intestinal dysfunction and gut microbiota remodeling in mice

bstract Didecyldimethylammonium chloride (DDAC) is a widely used quaternary ammonium disinfectant, but its effects on intestinal physiology following chronic oral exposure remain poorly understood. Here, we investigated the impact of chronic dietary DDAC exposure on intestinal fu...
