To evaluate the specificity of the PCR, genomic DNA of Theileria annulata,Babesia bovis,Toxoplasma gondii,Leishmania donovani and standard strain of N. caninum were used as a template in the PCR. For determining the detection limit of amplification procedure, PCR was run on a dilution series of genomic DNA from N. caninum（1.562 5-200 ng/ml）. Brain tissue samples of 32 aborted fetuses were detected by PCR-based assay, and 23 blood samples from mothers were tested by ELISA. Results The amplified DNA fragment （350 bp）had a high identity of 98% with the Nc-5 gene sequence of N.

以环形泰勒虫、牛巴贝斯虫、刚地弓形虫、杜氏利什曼原虫以及犬新孢子虫标准株DNA为模板进行扩增以验证PCR的特异性，采用紫外分光光度计测定犬新孢子虫标准株DNA浓度和纯度，取高纯度的DNA样品用灭菌水稀释，分别取不同量的DNA进行PCR扩增，确定PCR方法的敏感性；利用该方法对32份奶牛流产的胎牛脑组织样品进行检测，同时，对其中23份流产的母牛血样进行ELISA血清学检测，以评价犬新孢子虫PCR方法的检测效果。
