Abstract:

Objective To establish the relationship between hantavirus harborage and genetic factors in Rattus norvegicus. Methods The genomic DNAs of R. norvegicus carrying hantavirus and those not carrying hantavirus were amplified by microsatellite PCR. The positive and negative samples in the same area were compared in terms of ten microsatellite loci. Results The 48 lung samples from the R. norvegicus captured in the epidemic areas of hemorrhagic fever with renal syndrome were rechecked, and 8 positive samples (carrying hantavirus) and 16 negative samples (not carrying hantavirus) in the same area were selected. There were no significant differences between the positive samples and negative samples at 8 microsatellite foci, and it was not stable at the other two loci. Conclusion There are no significant differences between R. norvegicus carrying hantavirus and those not carrying hantavirus at the 10 microsatellite loci.

摘要：

目的 了解褐家鼠携带汉坦病毒与其遗传因素间的关系。方法 采用微卫星PCR技术对携带和未携带汉坦病毒的褐家鼠基因组DNA进行PCR扩增，根据所选的10个微卫星位点比较同一地区阴性、阳性标本间的差异。结果 复核肾综合征出血热疫源地所捕获的褐家鼠鼠肺标本48份，挑选8份阳性标本及对应地区的阴性标本16份。通过对同一地区携带与未携带汉坦病毒的褐家鼠间微卫星扩增结果比较得出，8个所选微卫星位点未显现出明显差别，其余2个位点不稳定。结论 经过对褐家鼠在10个微卫星位点的比较，未发现携带和未携带汉坦病毒的褐家鼠之间存在明显差别。
