Extraction of intraerythrocytic malarial parasites by phagocytic cells.

Phagocytosis is an intricate process adopted by some unicellular organisms as a feeding behaviour. It has developed in the tissues of multicellular organisms, both vertebrates and invertebrates, as a defence system to confine and eliminate foreign matter and, in this manner, protect the host against infection. During evolutionary development, phagocytic cells have evolved to show greater specificity. Lakshmi Kumaratilake, Antonio Ferrante, Jaliya Kumaratilake and Anthony Allison here describe a unique mechanism used by phogocytic leukocytes to engulf intra-erythrocytic malarial parasites.
