Abstract:
... Vibrio parahaemolyticus is a major seafood-borne zoonotic pathogen causing gastroenteritis in humans. Although antibiotics are the most effective chemical agents for V. parahaemolyticus, their abuse has caused the emergence of multidrug-resistant strains, affecting seafood safety. Here, we have isolated and characterized the V. parahaemolyticus bacteriophage VPG01 as an eco-friendly sustainable al ...

Abstract:
... In grasslands, the interactions of foliar fungal diseases and their host plants are largely dependent on grazing by large herbivores. However, the relative importance of direct (i.e. pathogen removal) and indirect effects (i.e. via changes in plant community composition) of long‐term grazing on foliar fungal diseases remains largely unexplored, especially under varied grazing intensities. We condu ...
