Report on Gut Associated Lymphoid Tissue (Galt) in Freshwater Fish Channa Punctatus (Bloch)

The present study describes the presence of intraepithelial leucocytes (IEL) and interlaminal leucocytes (ILL) in the various gut regions of Channa punctatus. Routine histological techniques were adopted, section were stained with haematoxylin and eosin (H&E) and Giemsa. Apart from the IEL and ILL other cell types were observed along the entire gut regions, such as mucus cells, goblet cells, enterocytes, mast cells, granular cells and plasma cells. The presence of lymphoid cells in dispersed manner indicates the presence of gut associated lymphoid tissues and common mucosal immune responses.
