title: Differential leucocyte count in both sexes of an Indian soft-shelled turtle (Lissemys punctata punctata).
abstract: Leucocytes were studied by measuring their size with the ocular micrometer, determining cell-nuclear ratio and by differential count in an Indian species of soft-shelled turtle, Lissemys punctata punctata. Investigation was carried out in both sexes of the adult animals. Large eosinophils have largest size; type A cell, small eosinophil and heterophil are moderately large; and basophil, lymphocyte and monocyte are relatively smaller. Nuclear ratio to cell is highest in the lymphocyte and lowest in the large eosinophil. Others have moderately high nuclear ratio. Heterophil and monocyte are smaller in males than in females. The nuclear ratio of monocyte and heterophil is also lower in the males than in females. Type A cell is most abundant, followed by eosinophil, lymphocyte, monocyte, basophil and heterophil. All types of leucocytes are more in male animals than in females except type A and heterophil which are less in the former than in the latter sex.
