- Abstract
The avian gut associated lymphatic tissue (GALT) is very important for understanding the immune response of the digestive system after oral administration of vaccines. This study is carried out on 6 apparently healthy mature pigeons. Two pigeons were used for gross morphology and the others for histological examination using H&E stain. There are different thickening at the digestive tube, like pharyngeao-esophageal junction, esophageo-proventricular junction and the two rudimentary ceca. The lymphatic tissue is organized in the propria sub mucosa as diffuse lymphatic tissue and lymphatic follicle (nodule). The epithelium in the intestine shows lymphocytic infiltration to form lymphoepithelium. The lymphatic nodules are located not only in the propria-submucosa, but also in the tunica muscularis and tunica serosa of the intestine.
