Side effects in sea bass (Dicentrarchus labrax L.) due to intraperitoneal vaccination against vibriosis and pasteurellosis

All the lesions observed were moderate, indicating that in sea bass, the pathological effects due to intraperitoneally injected vaccines are less severe than in other fish species. The divalent oil adjuvanted vaccine induced the most severe side effects, with macroscopic granulomas consistently present up to 11 months.
