Adaptation of a Nigerian strain of Plasmodium falciparum to Panamanian Aotus trivirgatus.

A patent infection (more than 190 days duration) with Plasmodium falciparum, obtained directly from a patient who had been exposed to malaria in Nigeria, was established in a splenectomized Panamanian owl monkey, Aotus trivirgatus griseimembra. Subinoculations from the original monkey recipient into one splenectomized and two normal A. t. griseimembra produced primary patient parasitemias of 18-54 days duration. These results represent the first successful adaptation of P. falciparum from man to a monkey of Panamanian origin.

Banding patterns of the chromosomes of two new karyotypes of the owl monkey, Aotus, captured in Panama.

Two new chromosome complements of Aotus trivirgatus griseimembra are described making a total of five different karyotypes observed in this subspecies inhabiting Panama and the northwestern part of Colombia, South America. Detailed comparisons of the G-banded chromosomes of these five karyotypes suggest that the polymorphism of chromosome numbers 56 and 55 in Panamanian Aotus and 54, 53, and 52 in Colombian Aotus stems primarily from a Robertsonian translocation mechanism involving pairs B13 and B14 (or A1). A second Robertsonian translocation mechanism involving pairs B28 and B29 (or A2) constitutes the karyotypic differences between the two chromosomal races.
