Suppression of PHA-stimulated lymphocyte transformation in cynomolgus monkeys following infection with Coxiella burnetii.
Phytohemagglutin (PHA) induced blastogenesis of peripheral blood lymphocytes from cynomolgus monkeys infected with C. burnetii was suppressed between 14 and 28 days after infection. Lymphocytes became responsive to PHA again on day 35 with an increase in stimulation index when cultured with specific antigens. In contrast, production of specific humoral antibodies was not diminished during the acute and early convalescent stages of infection.
