Chinook salmon (experimentally in other salmonids
as well). |

Every
organ, in particular kidney and spleen. |
| Type
of lesion |
Infiltration of proliferating plasmablasts.
Lobate nuclei with prominent nucleoli. |
|
Special features |
Indistinguishable
on the histological level from intranuclear
microsporidian infection in salmonids on the

differential diagnosis. |
| Diagnosis |
Immature blood cells in stained liver smears
and the occurrence of a renal interstitial hyperplasia
