Characteristic Immunohematological Parameters of Migratory (Vespertilio murinus Linnaeus, 1758) and Resident (Myotis dasycneme Boie, 1825) Bat Species of the Ural Fauna.

Abstract

The results of the first comparative analysis of hematological parameters of bats from natural populations of the Ural region are presented: the pond bat (Myotis dasycneme Boie, 1825), which is a resident species, and the two-colored bat (Vespertilio murinus Linnaeus, 1758), which is a migratory species. Significant differences in the content of white blood cells (p = 0.05), red blood cells and platelets (p = 0.001) were shown. Interspecific differences were found in the leukograms of the studied bats both in the content of granulocytes (p = 0.04) and agranulocytes (p = 0.05). Migrating V. murinus are characterized by a significant contribution of the nonspecific protective system of the blood (54.9%) to the adaptive reactions of the body. In the pond bat, a pronounced lymphocytic profile (58.5%) indicates the activation of acquired adaptive immunity. Two-colored bats in comparison with pond bats are characterized by a higher level of innate immunity.
