The investigation comprised physiological and histological exams of 70 women with Toxoplasmosis and 30 women who were not affected. Samples from 20 placentas were obtained from groups, as well as blood and physiological examinations. The findings of the current investigation displayed a fundamental increase in concentration of IP-10(133.5 ± 120) and MCP (220.9 ± 122) in blood serum of patients suffering from Toxoplasmosis infection and control group IP-10 (94.8 ± 82) and MCP (199.7 ± 76). There were histological changes in the placenta tissue in aborted women due to the rapid reproduction of the parasite, and large spaces in the tissue due to the parasite's formation of tissue bags, which resulted in the death of cells forming the placenta tissue due to the parasite's secretions and toxic substances. Abortion or congenital deformities in the pregnancy, as well as impairments to the newborn neurological system.

The Aim: This work to study Histopathological Changes in the Gastrointestinal Tract of Local Chickens Infected with Parasite Choanotaenia infundibulum. Place and Duration of Study: Raillietina cesticillus samples were obtained from the veterinary hospital with the help of specialized doctors. Study Design: A total of ten domestic hens infected with Choanotaenia infundibulum were investigated between March and July 2021 at the veterinary facility in Najaf Province, Iraq Methodology: Pathologically, there was a visible enlargement of the bowel, whereas histologically, alterations were more subtle. Unmistakable signs include inflammation of the epithelial layer and an abundance of cellular infiltration. Chronic inflammation and cell fragmentation in the epithelium Results: Macular degeneration as a result of the presence of this causes the villi to become disintegrated, removing any trace of the epithelial cells that line the digestive tract's villi and glands. Conclusion: It is noted that there is a smashing of the tops of the villi, sloughing, smashing, and inflammation in the epithelial layer of a wall accompanied by a large infiltration of inflammatory cells, especially eosinophils
