摘要: 目的 研究广西壮族自治区合浦县鼠疫自然疫源地主要宿主动物和媒介蚤的分布特征,为制定鼠疫防制对策提供依据。方法 对合浦县1987-2006年的鼠疫监测及防制资料进行分析和评价。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。结论 合浦县鼠疫自然疫源地处于静息期,每年的2月和9月是最适灭鼠期,1-7月是鼠疫监测的重点期。

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. Conclusion The results show that the natural infective foci in Hepu county remains in a quiescent period and the best rodent control months are February and September and the important surveillance period of plague is from January to July.
