The embryos of 6 to 14 days old were used for these experiments and were inoculated into the chorioallantoic membrane, amniotic cavity and yolk sacs. The results are briefly summarized as follows : 1. Regardless of the route of inoculation and number of Tp inoculated, the embryos showed very high susceptibility and were died. Even if they were hatched, the almost chickens succumbed to Tp within 2 days after hatch. 2. Survival periods of inoculated embryos were not depending upon the route of inoculation or age of embryos but largely upon the number of Tp inoculated. There are a close relation between number of Tp and duration of survival. 3. The most characteristic lesions in the embryonated eggs inoculated chorioallantoic or amniotic route were yellowish-white pocks, scattered throughout the allantoic membrane. The pocks were detectable about 3 days after inoculation and contained many parasites. 4. The dead embryos were deeply haemorrhagic. The parasites multiplied well in embryos' organs except the brain, and also in the chorioallantoic membrane and in the allantoic cavity. However, the case of yolk sac inoculation, the parasites were detectable only in a few organs with small in numbers. 5. From the results described above, it seems likely that embryonated eggs are highly susceptible as like as mice to toxoplasmic infection not according to their ages and the route of inoculation.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/4472"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
