Artifacts of formed elements and plasma of bird blood, their genesis and diagnostic significance

The work is devoted to the study of literature data (humane and veterinary medicine) and the practical analysis of artifacts formed elements and plasma in peripheral blood smears of birds in a model of broiler chickens Gallus gallus L. of early postnatal ontogenesis. The age of the studied clinically healthy chicks and young hens was: day 1, day 7, day 23 and day 42 (n = 40). We studied 158 (n = 158) high-resolution color micrographs of the fields of view, in blood smears stained according to Pappenheim. As a result, single artifacts of avian erythrocytes were identified: cytoplasmic vacuoles of various pattern character, scalloped «bitten» edges of cells. Artifacts of blood plasma were found: pericellular and adhesioned on the cell surface of colored coagulated granularity. In some cases, this granularity imitated the toxic forms of granulocytes and agranulocytes in the peripheral blood of birds. It is necessary to distinguish artifacts of cells and plasma in peripheral blood smears from adaptive changes and symptoms of infectious, invasive and non-infectious diseases.
