Malaria parasites of rodents of the Congo (Brazzaville): Plasmodium chabaudi adami subsp. nov. and Plasmodium vinckei lentum Landau, Michel, Adam and Boulard, 1970.

Descriptions are given of the blood forms, sporogonic stages and enzyme forms of Plasmodium chabaudi adami subsp.-nov. and P. vinckei lentum, malaria parasites of the thicket-rat Thamnomys rutilans of the Brazzaville region. The two species differ from each other in both morphological and enzymic characters. P.c. adami and P. v. lentum differ from the other subspecies of P. chabaudi and P. vinckei principally by their enzyme forms.
