Abstract

The immunologic status of rhesus macaques (Macaca mulatta) with naturally occurring disease was evaluated by determining the percentages of B and T lymphocytes and mitogen responsiveness of lymphocytes in peripheral blood and lymph nodes. The B lymphocytes were identified by the presence of cell surface immunoglobulin and receptors for complement. The T lymphocytes were identified by their ability to form spontaneous rosettes with sheep red blood cells. Rhesus macaques with idiopathic or primary amyloidosis had normal lymphocyte characteristics. Peripheral blood lymphocytes from rhesus macaques with atypical tuberculosis had decreased percentages of spontaneous rosette-forming cells and depressed responses to concanavalin A, and those with chronic diarrhea or chronic arthritis were also found to have abnormal peripheral blood lymphocyte characteristics. The percentage of B and T lymphocytes in normal lymph nodes was variable, making simultaneous histologic examination necessary for evaluation of diseased animals.
