Age differences in the leukocyte blood composition of the common viper Vipera berus (Reptilia: Serpentes: Viperidae)

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

The results of our comparative analysis of parameters of the leukocyte blood system of underyearlings and mature specimens of the common viper Vipera berus are presented. The material was the blood of 36 females and 26 males caught in the Middle Volga basin, and 13 underyearlings born in captivity from 4 females of this sample. V. b.

Comparative leukocyte blood profile of Emys orbicularis (Reptilia: Emydidae) from two populations

Authors: Romanova E. B., Stolyarova I. A., Bakiev A. G., Gorelov R. A.

A comparative estimation of the leukocyte profile of the marsh turtle Emys orbicularis (Linnaeus, 1758) living in the Ural river basin (Orenburg region, Belyaevsky district, 11 females and 5 males) and in the Volga river basin (Astrakhan region, Krasnoyarsk district, 28 females and 20 males) was made.

Leukocyte blood composition of Naturix natrix (Serpentes: Colubridae) in the Mordovian State Nature Reserve (Russia)

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

The state of the grass snake (Natrix natrix) population in the Mordovian State Nature Reserve was assessed using the hematological approach. The leukocyte blood count was estimated together with calculation of the associated leukocyte indices (neutrophil:lymphocyte (N:L), eosinophil:lymphocyte (E:L), heterophil:eosinophil (H/E) and heterophil:lymphocyte (H:L) ratios). The surface area of leukocytes (heterophils, basophils, eosinophils, azurophils, monocytes, and lymphocytes) was measured.

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

Authors: Romanova E. B., Nikolaev V. Y., Bakiev A. G., Klenina A. A.

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.
