Adoptive Transfer of Immunity to Plasmodium berghei
The Journal of Protozoology, 1969SYNOPSIS. Immunity to P. berghei in rats was transferred adoptively with spleen cells but not with bone marrow cells, thymus cells, peripheral lymph node cells or thoracic duct lymphocytes from immune donors. The parasite multiplies at the same rate in control and protected rats but when about 10% of host red cells are infected the number of infected ...

A marker epitope of attenuated Plasmodium berghei
Parasitology Research, 1988Plasmodium berghei XAT is an irradiation-induced, permanent attenuated derivative from high-virulence P. berghei NK65. Monoclonal antibodies against XAT were developed. By immunofluorescence screening, one monoclonal antibody was identified that was reactive with XAT at the schizont stage but not with NK65 nor with any other stage of intra-erythrocytic

Plasmodium berghei: T cell-dependent autoimmunity
Experimental Parasitology, 1980Abstract Plasmodium berghei infection in euthymic mice induced the formation of smooth muscle autoantibodies (SMA) persisting in cured immune mice. Antinuclear antibodies (ANA) were found in challenged hyperimmune mice, but not in acutely infected mice. The autoantibodies were not detected in infected and cured athymic, nude mice, and are therefore

Plasmodium berghei and Plasmodium knowlesi: Serum binding to sporozoites
Experimental Parasitology, 1980Abstract Plasmodium berghei salivary gland and oocyst sporozoites were examined with fluorescein isothiocyanate (FITC)-lectins to determine if sporozoites had carbohydrate-containing molecules on their surfaces. None of the eight fluorescein isothiocyanate-lectins bound to the sporozoites.

Auto-Antibody in Rats with Plasmodium berghei
Nature, 1960IN human malaria it has long been recognized that total loss of blood is significantly more extensive than loss which can be attributed to the direct rupture of parasites emerging from infected erythrocytes1. In a comparative survey of loss of blood and replacement in plasmodial infections of other mammals and birds, excessive erythrocyte destruction ...

Motility of Plasmodium berghei ookinetes in vitro
Journal of Invertebrate Pathology, 1975Abstract Motility of Plasmodium berghei ookinetes, which developed in primary and established cell line cultures obtained from Anopheles stephensi mosquitoes, was studied by using still photomicrographs and normal speed cinephotomicrography. At 18–72 hr after inoculation of P.

Pre-erythrocytic Development of Plasmodium berghei
Nature, 1965THE fate of the sporozoites of Plasmodium berghei in rodent hosts has been the subject of much research and speculation and has drawn the attention of malariologists from, the early days of the discovery of this parasite1. For it was evident to all that this useful and easily accessible Plasmodium, an instrument of great promise in biological and ...

Survival of Plasmodium berghei in Dead Hosts
The Journal of Parasitology, 1985the adult bopyrid. The only hypothesis that seems reasonable is that sex is genetically determined in the cryptonisci of P. expansus. However, after examination of over 400 Epipenaeon ingens Nobili, only 1 juvenile female bopyrid was removed from an adult E. ingens. On morphological grounds, this juvenile proved to be P.

In vitro Development of Plasmodium berghei Ookinetes
Nature, 1968AFTER a mosquito has fed on an animal infected with malaria, the microgametocyte exflagellates in the mosquito gut and fertilizes the macrogamete thereby forming an ookinete. Only a few workers have studied the in vitro cultivation of the mosquito stages of malaria.

Development of Infectivity by the Plasmodium berghei Sporozoite
The Journal of Parasitology, 1975Studies were done on the development of infectivity during ontogeny of the sporozoite of the rodent malaria parasite, Plasmodium berghei. Populations of sporozoites were separated from the oocysts, the hemocoel, and the salivary glands, with special precautions being taken to avoid cross-contamination between the different populations.
