Light microscopic morphology of blood cells of non‐descript indigenous Zoar chicken of Mizoram, India

Abstract

Identifying and analysing distinct blood cells is crucial for the diagnosis and treatment of diseases in the field of biomedicine. The present study was undertaken to study the cytomorphological and cytochemical characteristics of the blood cells of Zoar, a non‐descript indigenous breed of chicken extensively reared under backyard poultry farming in Mizoram, India. For this study, 2 mL of blood samples were aseptically collected from the wings veins of 12 chickens and were processed for light microscopic study under standard protocols. The matured erythrocytes were elliptical, while the immature erythrocytes appeared oval. The heterophils were positive for SBB (SBB), Periodic Acid Schiff (PAS), acid phosphatase, alkaline phosphatase and Arylsulphatase while the eosinophils were positive for SBB, PAS, alkaline phosphatase, cytochrome oxidase and peroxidase. The basophils of were positive for toluidine blue while the thrombocytes were positive for PAS. These cytochemical and cytoenzymatic staining properties plays a very important role in diagnosis, differentiation, and classification of leukaemias.
