Lymphocyte Phenotypes in Pheasants under Different Factors

For the phenotyping of lymphocytes we used spontaneous rosette tests and indirect rosette tests. Immunocytoadherent technic revealed that there is no difference in the absolute number of T- (E-ROK) according to the sex as well as the lymphocytes. Significantly higher values were detected in males compared to females B-lymphocytes We found that the number of B-lymphocytes (EAC-rossetes) and helper cells increases with age, and we showed the highest percentage of lymphocytes in autumn, which correlated with a higher percentage of T-helpers. The obtained data show not only the trends of the changes, but they are also the basis for analysis in various pathological conditions.
