This book explains how extracellular and intracellular protozoa of major tropical diseases interact with their hosts and host cells to achieve successful parasitism. The assembled articles represent recent advances made mainly in the biochemistry, cell biology and molecular biology of these parasites, with particular reference to the cell surface and other molecules relevant to the process of infection. Special attention is given to the molecular ingenuity of these parasitic protozoa in recognizing host cells and escaping recognition by host defense mechanisms. This book is a basis for cross...
