Immunocompetent cells of the turkey: age and organ distribution patterns of T and B lymphoid cells.
The percentage of lymphoid cells from the bursa of Fabricius, thymus, spleen, peripheral blood, and cecal tonsils reactin with chicken antisera to turkey bursa and thymus were evaluated, using 1-day-old to 5-week-old turkeys. For this, rabbit anti-chicken globulin fluorescein isothiocyanate conjugate was used. The percentage of lymphoid cells showing immunoglobulin surface determinants from these organs also was examined, using a direct immunofluorescence test with a rabbit anti-turkey globulin fluorescein isothiocyanate conjugate. This study suggests that the bursa-specific antigen and immunoglobulin surface determinants could be used as markers for bursa-derived cells in the turkey. It also was found that thymus-specific antigen could be used as a marker for thymus-derived cells.
