This study was aimed to investigate the ultrastructure of gut-associated lymphoid tissues (GALTs) in the small intestine of the Guineafowl. The distribution of lymphocytes, globular leucocytes (GLs), plasma cells, macrophages and mast cells in GALTs of digestive tract lymphocytes is the main population of the GALT, and GLs were sandwiched between epithelial cells throughout the intestine of the Guineafowl. Lymphoblasts could be distinguished by their size and relatively large amount of cytoplasm. Plasma cells with a dilated endoplasmic reticulum were seen among the lymphocytes and lymphoblasts in the ileum of an 180-day-old Guineafowl. It had a typical “clock-face” arrangement of the nuclear chromatin. Mast cells were located in the lamina propria just beneath the epithelium, and granules were moderately electron dense and bounded by a single membrane. Macrophages in moderate numbers were present throughout the lymphoid tissue, and both dead and dying cells could be seen within vacuoles in the cytoplasm.
