Bacterial disease

Histopathological changes

Vibriosis

Degeneration of the uriniferous tubules and glomeruli is generally conspicuous with interstitial hemorrhaging. Necrosis of muscle fibres.

Furunculosis

Degeneration of muscle fibres and necrosis. Exudations of large amounts of serum and haemorrhaging.

Red fin disease

Extreme hyperemia and hemorrhaging in interstitial region and in endothelial tissue of the atrium.

Pseudotuberculosis

The necrotized part in the centre is surrounded by epithelioid matter.

Red spot disease

Haemorrhaging in the lower layer of the epidermis, dermis and scales.

Columnaris disease

Necrosis in the branchial lamellar epithelium and in the capillaries.
