A correlation of the sequestration rate of Plasmodium coatneyi-infected erythrocytes in cerebral and subcutaneous tissues of a rhesus monkey.
Parasitized red blood cells (PRBCs) were sequestered in microvessels of cerebral and subcutaneous tissues of a rhesus monkey infected with Plasmodium coatneyi. A similar sequestration rate (approximately 80%) was observed in both cerebral and subcutaneous microvessels. Electron microscopy showed knobs of the sequestrated PRBCs cytoadhered to endothelial cells. These results are consistent with the finding of PRBC sequestration in subcutaneous tissues in a comatose patient with cerebral malaria. Biopsy specimens of subcutaneous tissue may be useful as indicators of PRBC sequestration in the brain of cerebral malaria patients.
