Sea bass immunity to parasitic disease could lead to new treatments

No effective licensed therapies exist against amyloodiniosis, a disease of fish species caused by Amyloodinium ocellatum (AO) ectoparasites. However, new research has shown that European sea bass (ESB) can develop specific immunity to the disease, which could in turn lead to the development of vaccines.
