Chicken Blood Smear
Gallus gallus domesticus
This peripheral blood smear specimen demonstrates the characteristic cellular composition of avian blood from a domestic chicken (Gallus gallus domesticus). Unlike mammalian erythrocytes, avian red blood cells (erythrocytes) are oval, flattened disc-shaped cells containing prominent centrally located, oval to elongated heterochromatic nuclei. Interspersed within the dense erythrocyte population are leukocytes, including heterophils with distinctive rod-shaped cytoplasmic granules, eosinophils, basophils, lymphocytes, and small nucleated thrombocytes responsible for hemostasis. Standard Romanowsky staining (Wright-Giemsa) colors the cytoplasm pale pinkish-orange and highlights the dense purple nuclear chromatin, providing a classic histological view of non-mammalian vertebrate hematology.
