| 中文摘要: |
| 用PCR/RFLP技术对北京郊区11个旅游景点的媒介蜱及小哺乳动物进行斑点热群立克次体的检测，并进行了病原体分离和鉴定。结果从北京航空博物馆附近地区收集的刺猬和其体表寄生的中华革蜱中分离出2株斑点热群立克次体，分别命名为BJH-95株和BJ-95株，经SDS-PAGE、Western blot和PCR/RFLP技术进行了鉴定认为是西伯利亚立克次体。结果证明了该立克次体在蜱和动物宿主间呈水平传播，并且表明在被调查的旅游景点中除航空博物馆附近地区外，大多数景点基本上是北亚热的安全区。在刺猬中分离出西伯利亚立克次体为国内、外首次报道。 |
| 英文摘要: |
| PCR/RFLP technique was used to detect spotted fever group rickettsiae (SFGR) in ticks and small mammals collected in eleven scenic spots of Beijing suburb.We not only detected Rickettsia sibirica in D.sinicus and hedgehog collected nearby the Museum of Aviation, but also isolated two strains of SFGR from them,named as BJ-95 strain and BJH-95 strain respectively. The two strains were identified as R.sibirica by SDS-PAGE,Western blot and PCR/RFLP. The results demonstrated the existence of horizontal transmission of R.sibirica between ticks and small mammals and showed the most scenic spots except the vicinity of Museum of Aviation being investigated were safe to North Asia Fever.This is the first report on the isolation of R.sibirica in hedgehogs. |
