Abstract The cell surfaces of four strains of Renibacterium salmoninarum , including the type strain Lea‐7‐74 T , were examined by transmission electron microscopy after immuno‐stabilization and staining with ruthenium red. Cells were covered with a layer of capsular material whose thickness varied between 30 to 60 nm. Our results indicate that R. salmoninarum is encapsulated.
