| Abstract | ||
| This study was designed to investigate the effect of the herb type Urtica dioica L on the pathogenesis in chicken meat (Rose strain) were experimentally infected by 1500 oocyst of Eimeria tenella at 22 day old age. It divided randomly into three equal groups at 7 days. The first group represented the positive control, while the second and third groups were treated with herbs at a concentration of 1% and 5% in the feed and aqueous extract respectively, every day of the experiment. Histopathological examination of liver, spleen, intestines and brain of control group revealed hepatic cell necrosis; complete lymphoid depletion in splenic and bursal tissue associated with neuronal degeneration and accompanied by presence numerous degenerated merozoites in cecum. While the histopathological examination in treated groups showed well developed proliferation lesions mainly when treatment with water. Examination revealed major histopathological changes in fodder treatment group, vascular congestion and sinusoidal dilation with periodical MNCs infiltration, bursal epithelial hyperplasia with reactive lymphoid hyperplasia in splenic tissue together with pyers patches lymphoid depletion with evidence of cystic formation in neuronal tissues of infected chicks mainly at 48 old day. | ||
