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.

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。
