Studies on the number and ingesting ability of thrombocytes in sick carps (Cyprinus carpio L.)

Abstract

Carps suffering from acute form of brachiomycosis (age: 2 months), chronic form of brachionecrosis cyprinorum (age: 12 months), acute form of erythrodermatitis (age: 23 and 28 months) or chronic form of erythrodermatitis (age: 23 months) were studied. The level of thrombocytes in carps with acute forms of the diseases was significantly lower than that in healthy carps. The inverse pattern was observed in carps with chronic forms of the diseases. Carps suffering from the acute form of erythrodermatitis (age: 23 and 28 months) demonstrated no differences in the level of thrombocytes which could be related to age or body weight of the animals. Index of thrombocyte ingesting ability and percent of ingesting thrombocytes were lowered in sick carps as compared to carp of control groups. A significant decrease in the parameters was disclosed, however, only in carps with acute forms of the diseases. Similarly to the level of thrombocytes, neither did the level of their ingesting ability demonstrate any differences which could be related to the age of carps suffering from the acute form of erythrodermatitis
