中文摘要: |
作者首次用来自立氏立克次体(R. rickettsii, Rr)190KDa蛋白抗原基因序列设计的一对引物扩增从黑龙江、河北、海南、北京采集的蜱、蜱卵、幼蜱、蜱粪及啮齿动物脏器中斑点热群立克次体DNA。从上述标本中均检测出了斑点热群立克次特异的532bp大小的DNA片段,该结果部分与同期进行的病原分离结果一致。故认为,PCR技术是一种快速、敏感、特异的斑点热群立克次体流行病学调查方法。 |
英文摘要: |
It was the first time that a primer pairs derived from the 190KDa protein antigen gene of R. rickettsii were used to amplify SFGR DNA in ticks, tick ova,larva,tick faeces and rodent organs which were collected in Hebei,Heilongjiang,Hainan nd Beijing. A 532bp fragment was respectively amplified from above samples.The results were partially in concordance with data obtained through rickettsiae isolation. It was suggested that PCR is a rapid,specific,sensitive and practical method for detection of SFGR in endemic foci. |
