Abstract:

Histology, histochemistry and ultrastructure of the lymphoid tissue in cloaca were studied in six White Leghorn chickens of three months of age. The lymphoid patches were distributed along the dorsal wall of the proctodeum of cloaca in all the birds. The tunica mucosa of cloacal lymphoid tissue consisted of a simple tall columnar lining epithelium which was modified into a lymphoepithelium. The scattered and aggregared lymphoid tissue were located in the lamina propria mucosae and submucosa. The goblet cells were lacking in proctodeum. But strong periodic acid Schiff’s (PAS) positive reaction was seen in proctodeal glands. The fibroblastic reticulum cell (FRC) in lamina propria, gave a reticular reaction for acid phosphatase. Since the lymphoid tissue was well developed in the cloacal patch further studies are required for identification of sites for local vaccine application for effective mucosal immune response in this species.
