Farmed fish are regularly subjected to various stressors due to farming practices, and their effect in the context of a disease outbreak is uncertain. This research evaluated the effects of unpredictable repeated stress in rainbow trout challenged with the ciliate , known to cause white spot disease in freshwater fish. Before and after the pathogen exposure, fish were handled with a random rotation of three procedures.

Article Synopsis
  • The study focuses on a protozoan parasite that poses a significant threat to the aquaculture and ornamental fish industries, infecting various parts of freshwater fish.
  • Researchers used transgenic zebrafish larvae to explore the early immune responses to this parasite by analyzing gene expression and the behavior of immune cells like neutrophils and macrophages.
  • Findings revealed that while zebrafish larvae exhibit an active local immune response, including the formation of neutrophil extracellular traps, the overall systemic inflammation remains mild, indicating the parasite's ability to evade stronger immune reactions through its dynamic movement.

The protozoan parasite Bonamia ostreae has been associated with the decline of flat oyster Ostrea edulis populations in some European countries. Control of shellfish diseases mostly relies on prevention measures including transfer restrictions and stock management measures such as breeding programmes. These prevention and mitigation measures require a better understanding of interactions between host and pathogens.
