Immunohematological indicators of non-poisonous and poisonous snakes on the territories of the Volga river basin with different antropogenic transformation

The comparative analysis of leukocyte blood formulas of poisonous and non-poisonous snakes of the territories of the Volga River Basin with different anthropogenic transformation was conducted by method of main components. The greatest contribution to discrimination on leukocyte composition of blood of snakes was made by eosinophils, basophiles, geterophils and lymphocytes. It is shown that the differences on the studied immune hematological indicators between samples of poisonous snakes were much larger than between samples of non-toxic. Sex variability in leukocyte composition of the blood of snakes is less signified than the biotopical and interspecific ones.
