| 目的 调查四川地区是否存在喜马拉雅旱獭鼠疫疫源地.方法 应用现场调查和实验室检测相结合方法,调查宿主动物及媒介蚤携带鼠疫菌的状况.结果 四川省德格县境内调查发现宿主动物10目30种(亚种);常见宿主动物为喜马拉雅旱獭和高原鼠兔,发现蚤类3科7属7种,喜马拉雅旱獭为鼠疫菌主要储存宿主,斧形盖蚤和谢氏山蚤为主要媒介,分离鼠疫菌13株;鼠疫间接血凝试验(IHA)阳性血清8份,牧犬血清最高滴度1:10 240,鼠疫反向血凝试验(RIHA)阳性19份,旱獭最高滴度1:409 600.四川省德格县境内鼠疫疫源地面积约4545 km2.结论 四川省存在喜马拉雅旱獭鼠疫自然疫源地 |

| Objective To explore the existence of natural loci on Marmota himalayana plague in Sichuan province and to provide basis for prevention and control of the disease. Methods Both epidemiological investigation and laboratory tests were used to provide the host animal and fleas of the vectors with Yersinia pestis carriers. Results 30 species of animals were found to belong to 10 orders. Ochotona curzoniae and M.himalayana were the most common ones while 7 species of the fleas belonged to 7 genera and 3 families. M.himalayana was the main reservoirs while Callopsylla dolabris and Oropsylla silantiewi served as vectors. The 13 Y.pestis were identified from 43 Marmota samples. 8 samples were identified under IHA, with the highest titer of herding-dogs serum as 1 : 10 240. 19 samples were F1 antigen positive using RIHA and the highest titer of M.himalayana serum was 1:409 600. The major foci was 4545 km2, distributed at Dege county in Sichuan province. Conclusion We have confirmed the existence of natural foci on M. Himalayana plague in Sichuan province. |
