摘要:   目的:探索弓形虫感染早期诊断方法。方法:用快速ELISA检测弓形虫感染鼠血清中弓形虫循环抗原。结果:在轻、中、重3个感染组,分别于感染后d4、d4及d3检测到弓形虫循环抗原。结论:感染虫体数量越多则弓形虫循环抗原测出时间越早,OD值亦越高。检测弓形虫循环抗原具有早期诊断价值。

Abstract:  AIM: To explore an assay method for the early diagnosis of Toxoplasma infection. METHODS: Serum samples collected from three groups of mice infected experimentally with different doses of Toxoplasma trophozoites were detected for the presence of Toxoplasma circulating antigen by using fast ELISA.RESULTS: Toxoplasma circulating antigen was detected on days 4, 4 and 3after infection in light, moderate and heavy infection groups, respectively. CONCLUSION: The level of circulating antigen was in parallel with the duration of infection. The determination of circulating antigen is useful in the early diagnosis of Toxoplasma infection.
