Nocardiosis in fish, caused by Nocardia seriolae (a kind of filamentous bacterium), is a severe disease in aquaculture, affecting over 40 species of marine and freshwater fish and causing great losses. To investigate the relationship between fish nocardiosis and the gut microbiota, we first artifici...
