Schizogony takes place in cells of the iaternal organs (bone- 

 marrow, liver, spleen, kidney) of Vertebrates. After several 

 generations of merozoites have been produced some of them 

 enter erythrocytes or leucocytes and develop into gametocytes. 

 These are taken into the body of a blood-sucking Arthropod 

 (tick, mite, louse, etc.) , and the micro- and macrogametes develop 

 and unite ia pairs. The zygote becomes encysted in the oocyst, 

 which increases enormously in size, eventually producing 

 sporoblasts, sporocysts, and sporozoites. Each large oocyst
