The present study aimed at the investigation of the plasma cells and eosinophil granulocyte localization and distrubution in the small intestine mucosa of the camel (Camelus dromedarius).  Small intestine samples (duodenum, jejenum, ileum) of six adult and healty one-humped camel were obtained from the slaughterhouse . Tissue samples were fixed by immersion in 10% neutral formalin saline and IFAA (isotonic formalin acetic acid) Ph:2.9. After routine histological procedure tissues embedded in paraffin. Sections (6m-thick) were stained methyl-green pyronin (MGP) for plasma cells, Congo Red for eosinophil granulocytes and Masson's trichrome stain modified by Crossmon for general view. In duodonum the plasma cells were concentrated at the type of villi (4-most intense) while few eosinophil granulocytes (2-less intense) that concentrated around the blood vessels were observed. The number of plasma cells were decreased in villus of jejenum (3-intense), at the same time the number of plasma cells in villus-crypt space were increased (3-intense). Eosinophil granulocytes were increased in villus of jejenum (4-most intense). In ileum, increased plasma cell numbers were observed in villus (4-most intense). Plasma cells were determined in aggregated lymph follicles. Eosinophil granulocytes were seen in villus of ileum (3-intense) while these cells were rarely observed in lymph follicles. As a result, it was determined that both plasma cells and eosinophil granulocytes were concentrated in the villi in the small intestines. In addition, plasma cells and eosinophil granulocytes were found to be located in the lymph follicles. It has been concluded that plasma cells and eosinophil granulocytes with increasing numbers of parasitic infections play an important role in preserving the intestinal health.
