结论确定四川德格县为喜马拉雅旱獭鼠疫自然疫源地。

Up to now, no Yersinia pestis was found in parasitic fleas except it was found in Marmota sibirica from Hulun Buir plateau in 1923. However, Y.

呼伦贝尔高原蒙古旱獭鼠疫自然疫源地于1923年仅自旱獭体中检出鼠疫菌，至今并未从寄生蚤中检出鼠疫菌。

Objective\ To study the susceptibility,sensitivity and antibody of Meriones meridianus in Tarim Basin to Yersinia pestis isolated from Marmota himalayana (strain No.21106), isolated from Marmota baibacina in Uqia, Xinjiang (strain No.98005), isolated from M.unguiculatus; To study the time of matrilineal antibody in newborn M.meridianus.

目的 研究塔里木盆地子午沙鼠对从新疆和田喜马拉雅旱獭鼠疫疫源地分离的 470 0 4号鼠疫菌、乌恰县灰旱獭体分离的 2 110 6号菌株和内蒙古长爪沙鼠体分离的 980 0 5号鼠疫菌株感染子午沙鼠在病理改变、感受性、敏感性、二次感染后抗性等方面有无差异，仔鼠体内的母系抗体维持时间。

Objective The survey and research of Microtus fuscus plague foci.

目的 研究青海省青海田鼠自然疫源地的分布。

The strains from Microtus fuscus ,however,had unique characters,significantly different from the strains isolated from other parts of China.

从该县青海田鼠中分离的鼠疫菌株，其分子生物学特征与我国其他疫源地中的鼠疫菌株明显不同。

There are Microtus fuscus plague foci in Qinghai Province.

青海省境内存在有青海田鼠疫源地。

Results Eight species belonged to three families, two orders of rodent animals and seven species of fleas were found in this area. Rattus losea and Xenopsylla cheopis were dominant species, R.flavipectus , R.norvegicus , Suncus murinus , and Banolicota indica were familiar species. The annual average density of rodents, the infected rate with flea of rodents, index of fleas, index of X.cheopis and free flea in room were 10.58%, 28.38%, 0.7916, 0.5702 and 0.0515 respectively.

结果 合浦县鼠疫疫源地的啮齿动物共有2目3科8种，以黄毛鼠为优势鼠种，黄胸鼠、褐家鼠、臭鼩鼱和板齿鼠为常见种；蚤类有7种，以印鼠客蚤为优势蚤种；年平均鼠密度、平均鼠体染蚤率、平均蚤指数和印鼠客蚤指数分别为10.58%、28.38%、0.7916和0.5702，地面游离蚤指数为0.0515。

Objective To isolate and identify Hantaviruses from reservoir animals captured in new nidi of HFRS in Ningxia.

目的 对宁夏肾综合征出血热新发疫源地进行宿主动物汉坦病毒的分离和鉴定。
