Résumé

The histological and cytological study of lymph node camel is highlighted by the use of immunohistochemical technique; we used two monoclonal antibodies CD3 and CD22 that have demonstrated the localization of lymphocytes in the lymph node. The appearance of follicular lymphoid cells detected by the reaction of the CD3 antibody was supported by a network of reticular fibers. The interfollicular tissue is composed mainly of lymphocytes. CD3 positive diffuse distributed. This reaction is expressed by most lymphocytes and interfollicular follicle tissue, lymphatic sinuses and post-capillary venules. Some cells are located in the cells of the cortex follicles. Superficial nodes are arranged in lymphoid follicles essentially spherical, are the major sites of localization and proliferation of B-cells. From this it was possible to classify the primary lymphoid follicles; that have no clear center and secondary follicles which include a clear center. The centers are the site of light proliferation of B-cells and germinal centers are called. Follicles "primary" could be "secondary" to rest. As the paracortex area consists mainly of T-lymphocytes, which is never as follicles in any case. Note that the medullary cords contain primarily B-cells
