2004-2007年河北省康保牧场鼠疫监测结果分析

Analysis of plague monitoring of Kangbao pasture from 2004 to 2007

目的分析2004-2007年康保牧场鼠疫监测资料,掌握其鼠疫疫情动态,提出预防控制对策。方法运用鼠疫流行病学方法,按照医学统计学进行统计、分析与评价。结果主要宿主动物长爪沙鼠平均密度0.01-5.01只/公顷,呈逐年降低趋势;达乌尔黄鼠的平均密度0.47-0.78只/公顷,相对比较稳定;达乌尔黄鼠鼠体蚤平均染蚤率43.66%-80.14%之间,平均蚤指数1.06-5之间,长爪沙鼠鼠体蚤平均染蚤率26.85%-35.05%之间,平均蚤指数0.35-0.97之间。达乌尔黄鼠窝巢染蚤率60%,平均蚤指数7.12。结论动物间鼠疫疫情发展稳定,但达乌尔黄鼠窝巢染蚤率和平均蚤指数较高。我们应加强监测,严防鼠密度的回升,坚持连续春秋两季灭鼠工作,并严防临近地区鼠疫的传入。

Objective To analyze the plague monitoring data, master the plague epidemic dynamic state in Kangbao pasture from 2004 to 2007. And provide the strategies for plague prevention and control. Methods Descriptive epidemiological methods and medical statistics were used for statistics, analysis and evaluation. Results The average density of main host in Meriones unguiculatus weve 0. 01 -5.01/ha, and decreased year by year; the average density of Citellus dauricus weve 0. 47 -0. 78/ha, and relatively stable; The average flea infectious rate of Meriones unguiculatus was 26. 85% - 35.05% and flea index was 0. 35 - 0. 97. The average flea infectious rate of Citellus danricus was 43.66% - 80. 14% and flea index was 1.06 - 5. The infectious rate of nest fleas of CiteUus dauricus was 60% and flea index wasT. 12 ; Conclusion The plague among the animal was stable. But the average flea infectious rate and flea index of Citellus dauricus nest were higher. We should strengthen plague monitoring to prevent the density increasing again, keep to kill rodents in spring and autumn, and prevent the plague spreading into from adjacent areas.
