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

Carps suffering from acute form of brachiomycosis (age: 2 months), chronic form of brachionecrosis cyprinorum (age: 12 months), acute form of erythrod ermatitis (age: 23 and 28 months) or chronic form of erythrodermatitis (age : 23 months) were studied. The level of thrombocytes in carps with acute fo rms 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 mo nths) demonstrated no differences in the level of thrombocytes which could be related to age or body weight of the animals. Index of thrombocyte inges ting ability and percent of ingesting thrombocytes were lowered in sick car ps as compared to carp of control groups. A significant decrease in the par ameters was disclosed, however, only in carps with acute forms of the disea ses. Similarly to the level of thrombocytes, neither did the level of their ingesting ability demonstrate any differences which could be related to th e age of carps suffering from the acute form of erythrodermatitis.
