Adrenal cortex alterations in mice infected with Plasmodium berghei.

: The ultrastructural study of adrenal cortex from Plasmodium berghei infected mice showed different degrees of capillary wall alterations including disruption and widening of the fenestrae, capillaries packed with parasitized erythrocytes, necrosis of cortical cells, parasitized erythrocytes outside capillaries and in some instances inside cortical cell cytoplasm. Lymphocytes were also observed in degenerated cortical cells. Our results suggest that adrenal cortex lesions may be relevant in the etiopathogenesis of severe malaria.
