摘要: 目的 分析3例输入性疟疾的实验室诊断,减少卵形疟的误诊与漏诊。方法 采用形态学检查、巢氏聚合酶链反应(PCR)及序列分析等方法确诊3例输入性疟疾病例。结果 3例患者形态学检查结果分别是未检出疟原虫(实验室初次检查)、检出卵形与恶性疟原虫和检出卵形疟原虫;巢氏PCR检测结果依次是卵形疟原虫感染、卵形与恶性疟原虫混合感染和卵形与间日疟原虫混合感染。结论 需加强疟疾消除地区疟原虫形态学检查技术的培训和推广。应用分子生物学检查技术可减少输入性卵形疟的误诊与漏诊。

Abstract: Objective To analyze 3 cases of imported malaria infection, in order to reduce the misdiagnosis and missed diagnosis of ovale malaria infection. Methods By morphological test, nested polymerase chain reaction (PCR) and sequence analysis were used to confirm the 3 cases of imported malaria infection. Results The morphological test results showed no plasmodium (laboratory initial inspection), plasmodium ovale mixed infection with plasmodium falciparum and plasmodium ovale. However, plasmodium ovale, plasmodium ovale mixed infection with plasmodium falciparum and plasmodium ovale mixed infection with plasmodium vivax were detected by nested PCR by follow. Conclusions The morphological technique training and the application of molecular biology techniques should be strengthen for imported plasmodium ovale malaria infection, and can reduce the misdiagnosis and missed diagnosis of imported plasmodium ovale malaria infection.
