对68例内因性葡萄膜炎(患病组)和57例非葡萄膜炎(对照组)进行血清弓形体抗体和弓形体DNA—PCR检测。发现患病组弓形体抗体阳性率为22.05％,对照组为9.61％,两组比较有显著性差异(P<0.05)。有家畜接触史者弓形体抗体阳性率为25.39％,无家畜接触史者弓形体抗体阳性率为6.5％,两者有显著性差异(P<0.05);而不同部位葡萄膜炎弓形体抗体阳性率之间无显著性差异(P>0.05)。讨论了弓形体抗体阳性的葡萄膜炎的临床特征。对PCR用于检测弓形体DNA低阳性率的原因作了初步探讨。
Toxoplasma gondii and Toxoplasma gondii were detected in 68 cases of endogenous uveitis (diseased group) and 57 cases of non-uveitis (control group). The positive rate of Toxoplasma gondii antibody was 22.05% in the control group and 9.61% in the control group, there was a significant difference between the two groups (P <0.05). The positive rate of toxoplasma antibody in the history of exposure to domestic animals was 25.39%, and the positive rate of toxoplasma antibody in the history of domestic exposure was 6.5% (P <0.05), while the positive rate of toxoplasma antibody in different parts of uveitis was There was no significant difference between rates (P> 0.05). Toxoplasma antibody-positive clinical features of uveitis are discussed. The reason why PCR was used to detect the low positive rate of Toxoplasma was explored.
