目的了解辽宁省建平县鼠疫疫区动态,为控制人间鼠疫提供依据。方法对建平县2009—2013年鼠密度、黄鼠生态学、媒介监测及病原学、血清学资料进行分析。结果黄鼠密度波动在0.10~0.23只/hm2;野外小型鼠密度波动在0.53~0.81只/百夹次,家屋鼠密度波动在0.88~1.80只/百间房子,2013年野外小型鼠监测发现新鼠种—短耳短尾仓鼠;黄鼠生态学观察,2009—2013年总体无变化,Ⅰ龄鼠每年均有上升;累计梳黄鼠体1 792只,染蚤鼠体168只,获蚤262匹,染蚤率9.38%,5年平均蚤指数0.15;累计探洞干1 810个,其中染蚤洞干102个,获蚤186匹,平均染蚤率5.64%,平均蚤指数0.10;累计挖黄鼠巢156个,染蚤巢56个,获蚤281匹,平均染蚤率35.90%,平均蚤指数1.80;动物细菌培养未分离出鼠疫杆菌,F1抗体—间接血凝测定试验均阴性。结论建平县鼠疫疫源地仍处于相对静止状态。 Objective To understand the dynamics of plague epidemic in Jianping County of Liaoning Province and provide basis for controlling human plague. Methods The rat density, gopher ecology, media monitoring, etiology and serology data from 2009 to 2013 in Jianping County were analyzed. The results showed that the density of squirrel fluctuated between 0.10 and 0.23 / hm2; the density of wild mice varied between 0.53 and 0.81 per 100 and the density of domestic house between 0.88 and 1.80 / The rat species - short-eared hamster; gopher ecological observations, the overall no change in 2009-2013, I-year-old rats were increased every year; 1 792 totransplanted rat body, 168 fleas infected with flea 262 The flea infection rate was 9.38% and the mean flea index was 0.15 for 5 years. The number of dry fleas was 1 810, of which 102 fleas were infected with fleas, 186 fleas with an average flea flea rate of 5.64% and an average flea index of 0.10. There were 156 chrysalid nests, 56 flea nests, 281 fleas were obtained, the average rate of flea infection was 35.90% and the average flea index was 1.80. The animals were not isolated from the bacteroides. F1 antibody - indirect hemagglutination assay was negative. Conclusion The plague origin in Jianping County is still at a relatively quiescent state.
