摘要:

目的 通过对三峡库区鼠疫宿主动物、媒介昆虫及鼠疫疫情的监测,为三峡库区及时发现和防控鼠疫提供科学依据。方法 鼠密度监测采用夹夜法;用鼠笼法捕活鼠采其血清检测鼠疫F1抗体,梳检活鼠体表寄生蚤检查染蚤情况,主动搜索不明原因自毙动物及开展疫情监测等掌握鼠疫疫情情况。结果 2007-2008年三峡库区重庆段平均鼠密度为1.49%,其中室内鼠密度为1.50%,室外为1.48%,褐家鼠、小家鼠、黄胸鼠及四川短尾鼩为优势种类;鼠体平均染蚤率为4.03%;总蚤指数为0.13;检获鼠蚤有不等单蚤(占0.12%)、缓慢细蚤(占77.88%)、偏远古蚤(占14.39%)和印鼠客蚤(占7.61%);6549只活鼠鼠疫血清学抗体检测结果均为阴性;未发现大批的不明原因自毙动物及鼠疫病例。结论 三峡库区重庆段尚未发现鼠疫疫情,但存在传播媒介和宿主动物。

Abstract:

Objective To provide the basis for early detection and control of plague in the Three Gorges Reservoir through monitoring of the host animals, insects and plagues in this region. Methods Night traps were used to measure the rat density. Live rodents were captured using cage traps to collect serum samples for detection of plague F1 antibody and determination of parasitic fleas on the rodent body. Animals which died of unknown causes were recorded, and plague monitoring was carried out. Results The average rodent density was 1.49% in Chongqing area of the Three Gorges Reservoir from 2007 to 2008. The indoor density was 1.50%, the outdoor 1.48%. Rattus norvegicus, Mus musculus, R. tanezumi and Anourosorex squamipes were the dominant species. The average flea-carrying rate was 4.03%, and the total flea index was 0.13. The parasitic fleas found on those rats included Monopsyllus anisus (0.12%), Leptopsylla segnis (77.88%), Palaeopsylla remota (14.39%) and Xenopsylla cheopis (7.61%). For the 6549 surveyed live rats, the serological test was all negative for plague. There was neither a large number of dead animals of unexplained causes nor plague cases. Conclusion Plague was not found in Chongqing area of the Three Gorges Reservoir, though the vectors and host animals exist.
