恶性疟血涂片见大滋养体1例

Large trophozoites in blood smear of falciparum malaria:one case report

本文报告1例非洲输入性非典型恶性疟病例,其血涂片显微镜下可见较多大滋养体期原虫,部分虫体可见棕黄色色素颗粒,呈点状或团块状,虫体形态与间日疟原虫、卵形疟原虫相似,经PCR基因检测确诊为恶性疟。非重症恶性疟病例外周血中出现大滋养体期原虫较为罕见,镜检时应注意与其他疟原虫鉴别。

This paper reports one case of atypical falciparum malaria imported from Africa,whose blood smear contains many large trophozoites,with punctiform or massive brown pigment granules,the body shape of the plasmodium is similar to that of Plas-modium vivax and Plasmodium ovale. After the gene detection by PCR,the case was diagnosed as falciparum malaria. As large tro-phozoites were rarely seen in the peripheral blood of non-severe falciparum malaria cases,much attention should be paid to the identification of Plasmodium falciparum and other plasmodia in microscopic examinations.
