目的 掌握锡林郭勒高原布氏田鼠鼠疫自然疫源地鼠疫疫情动态,为制订防治对策提供依据.方法 收集2001-2013年锡林郭勒高原布氏田鼠鼠疫自然疫源地鼠疫监测资料,统计主要宿主密度、染蚤率、蚤指数及细菌学、血清学检查结果,分析该疫源地鼠疫疫情流行情况.结果 13年间在锡林郭勒高原布氏田鼠疫源地共监测2 919.25 hm2,其中捕获布氏田鼠10 153只,平均鼠密度为3.48只/hm2.共布鼠夹43 632次,捕获鼠1 631只,捕获率为3.74％.病原学检查各种宿主动物22 752只,检出染疫动物104只,培养各种蚤6 437组,27 702匹,检出染疫蚤31组,79匹;用间接血凝试验方法检查布氏田鼠血清2 237份,检出布氏田鼠阳性血清2份,阳性率为0.09％.结论 在布氏田鼠疫源地内仍存在被鼠疫菌感染的宿主动物,未来仍存在鼠疫流行的可能,应进一步加强鼠疫监测工作力度,切实做好健康教育工作,严防动物间鼠疫流行波及人群.“,”Objective To analysis the plague monitoring results on plague of rats in Lasiopodomys brandti plague natural foci of Xilin Gol Plateau in Inner Mongolia from 2001 to 2013,to master the dynamics of the plague epidemic,and to provide a basis for developing countermeasures.Methods Plague monitoring data from 2001 to 2013 in Lasiopodomys brandti plague natural foci were collected,main host density,rate of dye fleas,flea body index,bacteriology,serology and epidemic situation were studied.Results Within 13 years,10 153 Lasiopodomys brandti were captured overlapping a monitored area of 2 919.25 hm2,the average rat density was 3.48/hm2;other small rodents were captured 43 632 times,and 1 631 mice were captured,capture rate was 3.74％.Totally 22 752 host animals were checked by etiology,104 animals were infected with epidemic diseases,79 fleas of 31 groups positive fleas were checked from cultured 27 702 fleas of 6 437 groups.Totally 2 237 serum samples of Lasiopodomys brandti were checked using indirect hemagglutination (IHA),2 copies were found positive,the positive rate was 0.09％.Conclusion In Lasiopodomys brandti plague natural foci of Inner Mongolia,the plague bacteria infected host animals are still existed,future outbreak is possible;the monitoring and health education should be strengthened,in order to prevent the plague spreading to human being.
