Morphology of Blood Cells of Agama stellio (Linnaeus, 1758)

by Open Science Repository Biology
(August 2013)


Ten Agama stellio healthy adults, five female and five males, were chosen for this study. They have been checked for morphological characteristics of peripheral blood cells. The Wright staining method was used for classification of the blood cells. Seven different types of blood cells were determined: erythrocytes, heterophils, eosinophils, basophils, lymphocytes, monocytes and thrombocytes. Mature erythrocytes of Agama stellio were nucleated ellipsoidal cells. Erythrocytes for males were (length 17.26 ± 2.61 µm × width 8.02 ± 2.02 µm) and for females were (length 17.69 ± 2.71 µm × width 8.34 ± 2.31 µm). The heterophil contain large, eosinophilic, ovoid, cytoplasmic granules with eccentric nucleus. The eosinophil is distinguished by its round, eosinophilic cytoplasmic granules and the nucleus is round to oval, single or bi-lobed. The basophil was easily identified by its deeply stained purple, large, round granules that remained tightly adhered to the centrally located nucleus. The lymphocyte contained a small amount of blue staining cytoplasm and a round nucleus with a fine reticular pattern. The monocyte contains a large amount of light bluegray, finely granular or vacuolated cytoplasm, and an oval or indented nucleus. Thrombocytes were oval-shaped cellscontained round, densely stained nucleus.
