Comparative Study On Tissue Cyst Diameters Of Toxoplasma Gondii Isolated From Placenta Of Women, Ewe And Goat Experimentally Inoculated In Mice And Chickens Embryo

Abstract

This study concerned on the measurement of tissue cysts diameter of Toxoplasma gondii that is isolated from placenta of different hosts (women, ewe and goat) and also comparing this diameters after injection of tissue cysts in another hosts (albino mice & chick embryo) in different times. Results show that the diameter of tissue cysts isolated from goat are the smaller one, followed by that isolated from ewe and women placenta, respectively. Also this study reveal no significant difference between tissue cysts diameter, which isolated from mice & chick embryo, while the difference is significant when those diameters compared with that isolated from the placenta of women (93 µm ± 0.76), ewe (55 µm ± 2.1) and goat (42 µm ± 2.03). and finally this study was done to determined the tissue cyst diameter variations of different strains of Toxoplasma gondii and its relation to the virulence , and by using this method in diagnosis protocol in the future
