Disturbances of cell-mediated immunity in ornithosis.
27 cases of ornithosis were observed during an epidemia in 1980 in Kielce and subsequently followed with respect to immunological characteristics of peripheral blood lymphocytes. Blastic transformation of these cells was tested after stimulation in vitro with three different mitogens. Identification of peripheral blood T and B lymphocytes was done using rosette tests (E,EA,EAC) and the occurrence of surface immunoglobulins was determined by the immunofluorescent method with polyvalent anti-immunoglobulin serum. The counts of T and B lymphocytes in the peripheral blood were normal throughout the whole period of the observation, but from the 3rd week on a significant impairment of 3H-thymidine incorporation into the cells stimulated with Con A was observed, and from the 10th week on, this impairment appeared also in cells stimulated with PHA and PWM. These observations revealed considerable disturbances in cell-mediated reactivity in patients with ornithosis and seem to be connected with chronic infection with Chlamydia psittaci.
