Salmonella pullorum-gallinarum binding to chicken lymphocytes has been evaluated in individuals of different age (1-20 wks). Bacterial adherence has been studied on lymphoid cells recovered from thymus, spleen, bursa and peripheral blood. Binding was age-dependent and neuraminidase treatment of lymphoid cells led to an increase of adherence. In addition, by using two monoclonal antibodies, the CT-1, which defines thymocytes and the M-4 which identifies surface IgM and an avian homologue of mammalian IgD on B lymphocytes, distribution of Salmonella pullorum-gallinarum binding to T and B lymphocytes has been analyzed. Results show that either T lymphocytes or B lymphocytes have the capacity to form rosettes with Salmonella. In particular, B cells from bursa and spleen display the highest capacity of adherence to bacteria, this supporting the defence function which has been attributed to bursa of Fabricius.
