COMPARATIVE DATA ON THE LEUKOCYTIC BLOOD FORMULA OF VIPERA BERUS AND VIPERA RENARDI

Authors: Romanova E. B., Solomaykin E. I., Bakiyev A. G., Gorelov R. A.

The leukocytic formulae of the peripheral blood of Vipera berus (Linnaeus, 1758) from the Samara region (Samara City) and Vipera renardi (Christoph, 1861) from the Saratov region (Khvalynsk district) were studied. Some features of the leukocytic blood composition of the species studied were revealed, manifested by the predominance of a specific component in the immune reactions of Vipera berus, in comparison with Vipera renardi.

LEUKOCYTE BLOOD COMPOSITION FEATURES OF GRASS SNAKE (NATRIX NATRIX) AND DICE SNAKE (N. TESSELLATA) (REPTILIA: COLUBRIDAE) FEMALES IN THE SAMARA REGION

Our study of the peripheral blood leukogram of grass snake and dice snake females (Samara region) has revealed changes in the blood of these snakes before and after their laying eggs, associated with the natural immunity activation in these animals. Natural, innate immunity reactions were mediated by mononuclear cells (monocytes and lymphocytes). An increase in the lymphocyte fraction in the dice snake female blood is shown to reduce the leukogram shift index.
