弓形虫感染的临床及实验诊断方法分析

目的：分析弓形虫感染的临床特点，探索简便有效的实验室诊断方法。方法：回顾性分析7例弓形感染临床表现，比较分析不同实验项目的诊断价值。结果：临床表现及一般实验室检查显示多系统损害征象。体液涂片找到弓形虫殡殖子或孢囊。在免疫吸附试验检测血清弓形虫IgM型抗体阳性；PCR检测体液弓形虫特异性DNA片段阳性是弓形虫感染的特有表现。结论：弓形虫感染临床表现及一般实验室检查缺乏特异性，弓形虫形态学，血清学及PCR检测对诊断具有决定性意义。

Analysis of Clinical and Laboratory Diagnosis Methods of Toxoplasma Gondii Infection

Objective:To investigate the clinical features of Toxoplasma gondii infection and the laboratory diagnosis method.Methods:The clinical features of 7 cases with Toxoplasma gondii infection were retrospectively analyzed.Results:The clinical features and laboratory results showed mutiple systemic damages.The Toxoplasma gondii trophozites or cysts were found in body fluid smear.The ELISA was used to check up the anti-Toxoplasma gondii IgM of the patients' serum,and the PCR was used to determine DNA segments of Toxoplasma gondii specificity.Conclusion:The clinical features and general laboratory diagnosis lack in specificity.It is very important to Toxoplasma gondii infection diagnosis in morphology,serology and PCR.
