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.
