| Abstract | ||
| This study aimed to use chicken embryos and hatched chicks, as an experimental model for the pathological study of Toxoplasm gondii isolates from placenta of women, ewe and doe. Chicken embryo infected by parasite which membrane (CAM and allantoic) nd yolk sac, five embryo were sacrificed at 3, 6 and 9 days post infection for each route to check the presence of isolate in allantoic fluid and the pathological changes mainly in brain, liver and heart. The result elucidated a positive isolation of the parasite at different stages of the parasite development in all periods of examination. Furthermore, these isolates revealed severe pathological changes in chicken embryo. On the other hand chicks that hatched from infected eggs showed clinical signs post hatching manifested by incoordination paralysis, blindness, and finally, death during a period 30 days pos infection | ||
