[Common characteristics of the invasion of host cells by sporozoa].

Sporozoan zoites contain specific organelles that are involved in host cell invasion, a process highly conserved within this phylum. The data obtained on different genera have shown high similarities in parasitophorous vacuole development, organelle exocytosis and integration of the organelle contents into the vacuole or the vacuolar membrane. Parallel investigations on invasion process in different genera will help sorting fundamental mechanisms of Sporozoan invasion out of the specific peculiarities.
