[The effect of the acid exopolysaccharide produced by the causative agent of melioidosis on macrophage function].

Acid exopolysaccharide of the melioidosis agent, isolated from the slime of alysogenic strain of Pseudomonas pseudomallei SVBDO-141 inhibits the capture of sheep erythrocytes--55Fe by mouse peritoneal macrophages. Administration of the sheep erythrocytes--55Fe, sensibilized by acid exopolysaccharide was proved not to have an antiphagocytic effect. Inhibition of phagocytic macrophagal activity depends on the conditions of isolation of acid exopolysaccharide.
