[Comparative analysis of phospholipid composition in erythrocytes of mouse-like rodents of different species].

Comparative analysis of phospholipid quantitative composition of blood erythrocytes has been performed in white (laboratory mice and rats) and wild (tundra voles) mouse-like rodents. A non-characteristic of mammals low relative content of sphingomyelin is revealed in erythrocyte phospholipids in tundra voles. A hypothesis is put forward that the unique composition of erythrocyte lipids is a peculiar evolutionary developed strategy of adaptation aimed at survival under condition of constant circulation of agents of leptospirosis in populations of this species.
