Abstract The distrubition of lymph nodes located in the abdominal and thoracic cavities of ten wild boars, and their structure were determined anatomically, histologically and immunohistochemically, to be the first detailed investigation on the wild boar. Though general localization and distribution were similar, the number of lymph nodes showed small differences from those of domestic pig. Histological investigations did not reveal a significant hilus. Besides, T lymphocytes with anti-CD3, CD4, CD8, B lymphocytes with anti-CD79a, macrophages with anti-macrophage monoclonal antibodies, and follicular dendritic cells using anti-S100 polyclonal antibody and their distrubution in the lymph nodes were detected. Many CD3 positive T lymphocytes were observed in the germinal center of the lymph follicles, in the cortical area and in the medulla. CD8 positive T lymphocytes were few, and CD4 positive T lymphocytes were not seen. CD79 positive cells were scanty. Top Keywords Anatomy, Histology, Immunohistochemistry, Lymphatic system, Wild boar.
