摘　　要：采用单卵囊分离技术,分离肠艾美尔球虫。根据GenBank中发表的肠艾美尔球虫18SrDNA序列,设计一对引物,建立PCR方法对其基因片段扩增并测序、比对。结果成功分离肠艾美尔球虫,PCR扩增出清晰条带,大小为528bp,最低能检出27个孢子化卵囊。该序列测定结果与Genebank发表的肠艾美尔球虫18SrDNA比对,相似性达98.5%。The pure strain Eimeria intestinalis was isolated by single oocyst separation technology , a pair of primer was designed according to the published 18S rDNA sequence of E.intestinalis in the GenBank, and a PCR method was established to amplify the gene fragment for sequencing and comparison. Results indicated that pure strain of E.intestinalis was isolated and its gene fragment was amplified with 528 bp in length. The PCR method could detect 27 sporulated oocysts. Similarity of gene sequences was up to 98.5% between the previously pub- lished 18S rDNA sequence of E.intestinalis and the amplified 528bp sequence by comparison.
