Toxicity of venoms of vipers Vipera renardi and V. berus for lizards

Results of research of toxicity of the east steppe viper Vipera renardi and common adder V. berus venoms for two species of lizards -steppe runner lizard Eremias arguta and sand lizard Lacerta agilis are given in the publication. Values of average half-lethal doses (DL50) of venoms samples make: DL50 of Renard’s vipersvenom for Eremias argutais defined as 12,1±2,85 μg/g, for a Lacerta agilis - 261,0±44,40 μg/g, DL50 of common adders venom is defined as 69,7±16,15 μg/g for a Eremias arguta and 502,9±76,38 μg/g for a Lacerta agilis. Interspecific distinctions in toxicity of V. renardi and V. berus venoms for both species of lizards are statistically significant.
