Anatomical distribution of developing trophozoites and schizonts of Plasmodium vivax in Aotus lemurinus lemurinus and Saimiri sciureus.

Organ distribution of developing trophozoite- and schizont-infected erythrocytes of Plasmodium vivax and night monkeys, Aotus lemurinus lemurinus, and squirrel monkeys, Saimiri sciureus, was determined. The primary site for the infection in both species was the splenic vasculature. Secondary organ involvement differed between hosts although some overlapping did occur.
