Abstract:

Objective To evaluate the application of 5S-23S rRNA and outer ospA genes in PCR?based detection of Borrelia burgdorferi and to investigate the infection with B. burgdorferi in rodents of Zhejiang province, China. Methods PCR was used to amplify 5S-23S rRNA and ospA gene fragments from 100 mice collected from different areas of Pan’an county. PCR products were purified and sequenced. Results Of the 100 mice investigated, 3 were positive for 5S-23S rRNA gene of B. burgdorferi and 5 for ospA gene of B. burgdorferi. The sequences of PCR products were found with high homology to the reference genes. Conclusion B. burgdorferi can be detected from rodent samples by PCR amplification of 5S-23S rRNA and ospA genes.

摘要:

目的 探索5S~23S rRNA和ospA基因序列在伯氏疏螺旋体检测中的应用, 了解浙江省鼠中感染伯氏疏螺旋体状况。方法 用PCR方法, 检测磐安县100只鼠标本中5S~23S rRNA和ospA基因特异片段。对检测到的阳性结果进行测序。结果 检测100只鼠标本, 其中3只鼠标本伯氏疏螺旋体的5S~23S rRNA基因片段为阳性, 5只鼠标本伯氏疏螺旋体的ospA基因片段为阳性, 与参考核酸序列基本一致。结论 利用ospA和5S~23S rRNA基因能从标本中检测到伯氏疏螺旋体。
