Abstract
The thymus was collected from day old to nine months of age at monthly interval.
Histomorphologically, the thymus gland in guinea fowl consists of cortex and
medulla. Cortex was composed of small and medium sized lymphocytes, myoid cells
and few Hassall’s corpuscles located in the meshwork of reticular cells. The medulla
consisted of less densely packed medium and large sized lymphocytes with relatively
more reticular cells and Hassall’s corpuscles. The reticuloepithelial cells were large
cells with long cytoplasmic process located in both the region. Myoid cells were
frequently found in the medulla and in the corticomedullary region, occasionally
found in the cortex. Hassall’s corpuscles were observed commonly in the medulla and
less frequently in the cortical and corticomedullary junction. Plasma cells, mast cells,
erythrocytes and macrophages were found both in the cortex and medulla.
