摘要
目的 分析宁夏北部沙鼠鼠疫监测结果,掌握鼠疫疫情动态,为制订防治对策提供依据.方法 收集2009年宁夏北部沙鼠鼠疫疫源地监测结果资料,统计主要宿主密度、染蚤率、蚤体指数及细菌学、血清学检查,分析该疫源地鼠疫疫情流行态势.结果 主要宿主平均密度为1.74只/hm2,平均染蚤率为28.60％,平均鼠体蚤指数为0.76.监测发现4起鼠间鼠疫疫情,共检出鼠疫菌16株,其中长爪沙鼠检菌10株、子午沙鼠2株、同型客蚤2株、秃病蚤2株.间接血凝检测（1HA）529份,发现阳性材料2份,血凝阳性率为0.38％；反向间接血凝检测（RIHA）8份,发现阳性材料7份,血凝阳性率为87.50％.结论 近年宁夏沙鼠鼠疫疫源地动物间疫情活跃,鼠密度较高,局部发生了鼠间鼠疫疫情,应加强监测力度,扩大监测范围,密切注视疫情动态,严控动物疫情的流行和蔓延,防止发生人间鼠疫.
Objective To analyze gerbil plague in northern Ningxia and the monitoring results,to master the plague epidemic dynamics,and to provide the basis for developmenting countermeasures.Methods Monitoring data of gerbil plague focus in northern Ningxia were collect in 2009,counted main host density,rate of dye fleas,flea body index and bacteriology,serology detect and analyzed the epidemic situation.Results An average density of main host was 1.74/hm2,the average rate of infected fleas was 28.60%,and the average rat body flea index was 0.76.Monitoring found 4 plagues from rat plague epidemic,plague bacteria were found in 16 strains,of which gerbils inspection bacteria 10 strains,Meriones unguiculatus 2 strains,the same type cheopis 2 strains,and bald disease fleas 2 strains.Indirect hemagglutination （IHA） was used to test 529 copies of samples,2 copies were found positive,and hemagglutination-positive rate was 0.38%; eight copies were examined by reverse indirect hemagglutination（RIHA）,7 material were found positive,and hemagglutination-positive rate was 87.50%.Conclusions In recent years,the disease is active among animals in gerbil plague focus Ningxia.The density of rodents is higher,and local plague epidemic is found in rats.Monitoring efforts should be strengthened and scope of monitoring should be expanded.We should pay close attention to the epidemic dynamics,control the prevalence and spread of animal disease,and prevent the occurrence of human plague.
