[Characteristics of the damage to immunocompetent organs in experimental slow influenza infection].

Morphological changes in immunocompetent organs were studied in 30 mice with slow influenza infection. Histological, histochemical, and electron microscopy studies revealed destructive changes in different cell populations of the thymus and spleen. The changes were more pronounced in the reticuloendothelial cells of the thymus and endothelium of thymic capillaries. Complex examination helps to outline the general pathological patterns in interpreting the pathogenesis of experimental slow influenza infection.
