| 摘 要： | 为探讨通过PCR技术检测Pf60.1基因来诊断恶性疟的可行性，采用PCR技术检测了4年前采集贮存的20例疑似疟疾病人的血样。阳性对照为恶性疟原虫FCC1／HN培养株；阴性对照为食蟹猴疟原虫、间日疟原虫及非疟区的正常供血员血样。结果为FCC1／HN株、12例镜检定为恶性疟和2例混合感染的血样扩增出长度为313bp～320bp的特定Pf60.1基因片段；而阴性对照均未产生DNA带型。此结果说明检测Pf60kD中的Pf60.1基因片段的方法稳定性好，特异性强和敏感性高，是恶性疟诊断的理想方法之一。

| Abstract: | To explore the possibility for diagnosis of falciparum malaria by detecting Pf60.1 gene, blood samples of 20 suspected malaria cases collected 4 years ago were tested by PCR. In the experiments, the FCC1/HN laboratory strain was selected as positive control, and P. cynomolgi, P. vivax, as well as normal blood samples collected from a blood donor living in non-malaria area as negative controls. The results showed that the FCC1/HN strain, the samples of 12 falciparum malaria cases and 2 mixed infection cases with both P. falciparum and P. vivax produced 313bp～320bp special gene fragments. However the negative control samples did not produce the special DNA band, indicating the method of detecting Pf60.1 fragment of Pf60 kD gene family had favorable stability, specificity and sensitivity. The authors suggest that it would be one of the practical methods for diagnosis of falciparum malaria in epidemiological investigation. |
