Host-like molecules in human malarial parasites

Malarial Fevers and Malarial Parasites

Studies on Malarial Parasites

1. Methods have been described for the preparation and sterilization of a synthetic nutrient medium which supports normal growth during one 24 hour asexual cycle of the erythrocytic form of P. knowlesi. 2. Successive subcultures with good multiplication can be carried out when whole blood or plasma is added to the medium. Data are presented from two such experiments where the sixth and seventh ...

Exflagellation of malarial parasites in human peripheral blood.

Exflagellation of microgametocytes in malarial parasites is associated with the life cycle in the mosquito. However, it is not found with the usual developmental phases in humans. This report describes two case reports where exflagellation of microgametocytes was observed in vitro in patients documented to have Plasmodium vivax malaria.

Molecules released by helminth parasites involved in host colonization.

Parasites are designed by evolution to invade the host and survive in its organism until they are ready to reproduce. Parasites release a variety of molecules that help them to penetrate the defensive barriers and avoid the immune attack of the host. In this respect, particularly interesting are enzymes and their inhibitors secreted by the parasites. Serine-, aspartic-, cysteine-, and metallopr...
