. Chronic mortalities associated with meningeal and pancreatic lesions are described, from two trout farms in Scotland. Histopathological and microbiological studies suggested that bacterial infection with strains of Pseudomonas fluorescens of low pathogenicity was developing in fish already affected by the lesions of chronic infectious pancreatic necrosis virus infection (IPN). Antibiotic therapy reduced losses temporarily; eradication of the virus resulted in complete elimination of the condition.
