Imported malaria cases are a potential threat to countries attempting elimination or working to prevent resurgence. We report the first imported Plasmodium ovale infection with molecular confirmation in Central America, which occurred in a Guatemalan soldier that had been deployed in Africa. The obstacles for its diagnosis using the standard microscopy technique and the need to improve its detection are discussed.展开更多
目的应用巢式PCR扩增小亚单位核糖体核糖核酸(18S r RNA)基因确诊卵形疟原虫感染。方法采集2012-2013年山东省疟疾患者全血和滤纸血样,吉氏染色镜检观察血膜疟原虫形态并鉴定虫种。提取血样中DNA,根据疟原虫18S r RNA基因以属和种特异...目的应用巢式PCR扩增小亚单位核糖体核糖核酸(18S r RNA)基因确诊卵形疟原虫感染。方法采集2012-2013年山东省疟疾患者全血和滤纸血样,吉氏染色镜检观察血膜疟原虫形态并鉴定虫种。提取血样中DNA,根据疟原虫18S r RNA基因以属和种特异性引物进行巢式PCR扩增,筛查卵形疟阳性标本并进行测序验证。结果2012和2013年山东省共筛查到7例输入性卵形疟原虫感染病例。巢式PCR扩增7份血样均在800 bp处出现卵形疟原虫特异性单一条带,Blast比对表明产物序列与Gen Bank卵形疟参考序列一致。结论经巢式PCR方法确诊了2012和2013年山东省7例输入性卵形疟病例。展开更多
