| Abstract | ||
| Parasitic infections in rodents are interesting area of study due to their role as reservoirs for many zoonotic parasites. The current study surveyed the intestinal parasites in 37 adult rats Psammomys obesus which captured from saline marsh areas of North Coast after Alexandria, Egypt by Abu Rawash hunters. Rats were investigated for intestinal protozoa with their pathological changes. Eight rats (21.6%) were infected by protozoa of total examined rats represented by Sarcocystis (one rat, 2.7%) and Eimeria (7 rats 19.9%). Examination of histological sections of small intestine revealed some developmental stages of Eimeria sp. Include schizont, male and female gametocytes in the lumen, mucosa and lamina propria of intestine. Degeneration, destruction, sloughing, denudation and hyperplasia of epithelium of intestinal villi were also noticed. In addition hyperplasia of Peyer's patches with lymphocytic infiltration were observed. Sarcocysist sp. was found in muscularis and intestinal submucosa with the resultant of destruction of the villi and crypt atrophy of the adjacent cells and discontinuity of the muscularis mucosa due to cyst formation. | ||
