Comparative mitogen responses of lymphocytes from Colombian Panamanian, and Peruvian owl monkeys.
A comparative study of lymphocyte responses to various mitogens, an index of cell-mediated immune competency, was made under various culture conditions using peripheral blood lymphocytes from Colombian, Panamanian, and Peruvian Aotus monkeys. Dose response curves were determined for each primate group to phytohemagglutinin, concanavalin A, and pokeweed mitogen stimulation. Considerable variation in mitogen response was observed. The influence of culture media supplemented with fetal calf serum or autologous plasma, the number of cells per culture, and the duration of incubation on mitogen responsiveness was also evaluated. Optimal lymphocyte culture conditions also differed among the three groups. Owl monkeys from the same location in South and Central America showed similar responses to physical condition and free of detectable disease, these differences probably reflect fundamental inherent biological differences between subpopulations of owl monkeys.
