INTRODUCTION: Paratuberculosis, commonly known as Johne’s disease, is a chronic intestinal infection of ruminants caused by Mycobacterium avium subspecies paratuberculosis (MAP). Clinical signs, including reduced milk yields, weight loss and diarrhoea, are typically abse...
Staphylococcus aureus is a major human pathogen responsible for severe infections. While traditionally described as extracellular, increasing evidence establishes S. aureus as a facultative intracellular pathogen. Intracellularity contributes to immune evasion, dissemination, and antibiotic failu...
Bacterial extracellular vesicles (EVs) are known to mediate intercellular communication, virulence, and immune modulation. Here we show that bacteria can utilise EVs also as recyclable nutrient reservoirs. Using Bacillus cereus as a model organism, we demonstrate that EVs exhibit distin...
In recent years, with the deepening of research on intestinal microbiota, we found intestinal microbiota plays an important role in host immune regulation and barrier maintenance through cross-talk between the microbiota and the host. New evidence suggests that disruption of the fragile balance w...
