Can Babesia infections be used as a model for cerebral malaria?
Infections with certain species of Plasmodium and Babesia induce, among other symptoms, cerebral pathology. The finding of heavily parasitized cerebral capillaries upon postmortem examination has led to the assumption that blockage of capillaries with infected red blood cells caused the cerebral symptoms and subsequent death. As this type of cerebrovascular pathology is found both in humans dying from malaria and in cattle dying from babesiosis, the latter could possibly be used as an animal model for the study of human cerebral malaria. However, before such a model system is adopted, the experimental data concerning cerebral pathology of babesiosis needs critical evaluation. Here, Theo Schetters and Wijnand Eling review the pathological mechanisms in cerebral babesiosis and relate these to cerebral malaria. Finally, they discuss the use of animal model systems for specific aspects of the pathological picture.
