Exoerythrocytic stage parasites of Plasmodium malariae were obtained in vitro by inoculating primary cultures of hepatocytes from a chimpanzee (Pan troglodytes) and a monkey (Aotus lemurinus griseimembra) with sporozoites. Schizonts were observed in chimpanzee hepatocytes 8, 11, and 13 days after inoculation. Only 1 schizont was seen in Aotus hepatocytes at(More)
Cytoadherence to HB3 and FC27 strains of Plasmodium falciparum-parasitized red blood cells (PRBC) was studied under shear conditions to elucidate the pathways of adherence to microvascular endothelial cells (MEC). HB3 PRBC bound exclusively to MEC CD36 and intercellular adhesion molecule-1 (ICAM-1) receptors. FC27 PRBC bound to CD36 and another unidentified(More)
Primary cultures of Macaca mulatta hepatocytes infected with sporozoites of Plasmodium knowlesi, P. cynomolgi (Cambodian strain), and P. cynomolgi bastianellii were exposed in vitro to 7 antimalarial compounds. The number of exoerythrocytic schizonts present after 4-7 days of culture was used to assess the activity. With pyrimethamine, proguanil,(More)
We studied the brains of rhesus monkeys infected with the primate malaria parasite Plasmodium fragile. Electron microscopy showed that, in these animals, erythrocytes infected with P. fragile undergo sequestration and that parasitized red blood cells adhere to endothelial cells in the cerebral microvessels by means of knobs. Cerebral microvessels with(More)
Exoerythrocytic stage parasites of Plasmodium fieldi and Plasmodium simiovale, 2 simian malaria parasites related to the human malaria parasite Plasmodium ovale, were cultured in vitro by inoculating primary cultures of hepatocytes from rhesus monkeys (Macaca mulatta) with sporozoites. Less than 1% of sporozoites developed into schizonts for either species.(More)
Surface proteins from several different life-cycle stages of the malaria parasite Plasmodium falciparum were expressed at high levels in the yeast Saccharomyces cerevisiae. Purified proteins, both individually and in cocktails, were used to immunize mice and goats in conjunction with either Freund's adjuvant or a muramyl tripeptide-based adjuvant. Immune(More)
