Ewes were inoculated orally with 1500 Toxoplasma gondii oocysts at 6 to 14 weeks of pregnancy. Abortions occurred at 26 to 55 days after inoculation, and maternal serum T. gondii antibody titres did not peak/plateau until 20 to 103 days after inoculation, usually after abortion occurred. Serums or body fluids from unautolysed foetuses aborted at 35 days or more after maternal inoculation, contained significant levels of Toxoplasma antibodies as determined by the indirect fluorescent-antibody test. It was considered that foetal serology was a quick and efficient method of diagnosing congenital toxoplasmosis in sheep on a flock basis.
在妊娠6至14周时，给母羊经口接种1500个刚地弓形虫卵囊。接种后26至55天出现流产，母羊血清弓形虫抗体滴度直到接种后20至103天，通常是在流产发生之后才达到峰值/趋于平稳。通过间接荧光抗体试验测定，在母羊接种后35天或更长时间流产的未自溶胎儿的血清或体液中，含有高水平的弓形虫抗体。据认为，胎儿血清学是一种在群体基础上诊断绵羊先天性弓形虫病的快速有效的方法。
