“…These observations of the present findings are in line with reports made by Kannan et al (2015) in fowl, Gulmez and Aslan (1999) in Geese, Tamilselvan et al (2017) in Guinea fowl, Hashimoto and Sugimura (1976) in Pekin duck and Senapati et al (2015) in quail, chicken and duck. Th ese work ers repo rted the sim ilar morphology of Hassall's corpuscles.…”

“…Similar reports were also made by Treesh et al (2014) in chicken, Gulamez and Aslan (1999) in Geese, Song et al (2012) in ostrich chick and Davison et al (2008) in avian. The findings of the present study regarding the components of thymic capsule and septa and lobulation is in accordance with those reported by Ali et al (2016) in turkey, El-Zoghby and Attia (2007) in ostrch and Tamilselvan et al (2017) in guinea fowl. These workers reported that capsule and vascularised speta was mainly composed of collagen and reticular fibres.…”

“…The increase in number of hypertrophied epithelial reticular cells was found to be increase with the advancement of age (Fig 5). In agreement with the present findings, El-Zoghby and Attia (2007) in ostrich, Ali (2016) in turkey, Tamilselvan et al (2017) in guinea fowl, Gilmore and Bridges(1974) in fowl and Davison et al (2008) in avian reported more number of epithelial reticular cells in the thymic medulla.…”

“…The medulla was composed of cellular population of lymphocytes, lymphoblast, epithelial reticular cells, myoid Histomorphological Study of Thymus in Japanese Quail (Coturnix coturnix japonica) cells, macrophages, plasma cells and structures like cyst and Hassall's corpuscles (Fig 4). This is in line with the reports made by Tamilselvan et al (2017) in guinea fowl, Haseeb et al (2014) in chicken and Hashimoto and Sugimura (1976) in pekin duck. These workers reported the similar components of the thymic medulla.…”

Background: Thymus is the primary lymphoid organ in avian. It is a site of differentiation and maturation of T lymphocytes. Quail thymus showed age related involution with decrease in its volume and cellular contents. It is a lymphoepithelial organ and thus plays a major role in the anti-infection defense mechanism. Methods: For the present study 48 Japanese quail birds reared and thymus was collected from 12 birds each at end of first week, second week, third week and fourth week. The tissue was processed for routine paraffin embedding and processed for different staining procedures for histomorphological studies. Result: In all age group of birds, each thymic lobe was enclosed by thin connective tissue capsule. Thymic lobule was found to be composed of outer cortex and inner medulla. Cortex was composed of lymphocytes, lymphoblasts, myoid cells, macrophages, plasma cells and epithelial reticular cells and that of medulla was composed of lymphocytes, lymphoblast, epithelial reticular cells, myoid cells, macrophages, plasma cells, cyst and Hassall’s corpuscles. The cyst of various shapes and sizes were observed in cortex and medulla. In all age group of birds, unilamilar and multilamilar Hassall’s corpuscles were observed. Number of Hassall’s corpuscles and macrophages were increased with the advancement of age.
