Hematological and histopathological changes in leukemia of bream - Abramis brama (L.)

Abstract

The nature of anatomo-pathological and histopathological changes as well as the quantitative and qualitative evaluation of the peripheral blood and the hemopoiesis centres allowed to detect symptoms of leukemia in a bream female. The picture of changes indicates to a certain similarity between this disease and a form of granulocytic leukemia occurring in animal, particularly in hens. Since the literature available provides no description of any similar disease in fishes had been found, we have attempted to give a detail characteristics of these changes.
