[Host-parasite interactions: mechanisms for recognition and attack].

Host-parasite interactions were studied by several researchers in these last years, both to better understand some parasite diseases and to identify new targets and strategies for the control of these infections. In this paper some of the most important recognition's mechanisms demonstrated between specific parasite structures and host cell receptors are reported, and particularly those concerning protozoa Leishmania, Plasmodium, Entamoeba, Giardia and Pneumocystis.
