This study was conducted to determine the biological effects of both Artemisia herba alba and Urtica dioica on the pathogenesis of Eimeria tenella, so 150 broilers, 7days old (Ross breed) were used, divided randomly into 6 groups. The first fourth groups include 30 chicks for each group, while fifth and sixth groups have 15 chicks for each, consider as positive and negative groups.The first five groups infected orally with 1000 oocysts of E.tenella directly into the crop at 17 days old. Histopathological examination of cecae in the treated groups with Urtica dioica revealed moderate mononuclear cells (MNCs) infiltration, while sever lymphocytic aggregations were seen in the treated group of water extract comparing with less cellular inflammatory infiltration was seen in the treated group with Artemisia herba alba .Severe degeneration and necrotic changes were appeared in epithelial layer of mucus glands as well as appearance of degenerated schizonts in the section of the control group.
