摘要
目的分析内蒙古自治区乌兰察布市2018年鼠疫监测结果,掌握鼠密度变化及鼠间鼠疫流行情况,为科学防治鼠疫提供依据。方法2018年4-11月,依据《内蒙古自治区鼠疫监测工作方案》,在乌兰察布市四子王旗、察右后旗、化德县、商都县进行鼠疫监测。采用一日弓形夹法进行鼠密度调查;采用5米夹线法进行小型啮齿类动物调查。通过样方法、5米夹线法、逐日法、收集病死动物等方法获得各啮齿类动物,梳检捕获鼠体蚤及鼠巢蚤,并对捕获的各啮齿类动物及蚤类进行病原学检测;采集啮齿类动物血样,采用间接血凝试验方法进行血清学检测。实验室检测及阳性判定依据《鼠疫诊断标准》(WS 279-2008)。结果共调查样方416 hm^2,捕获鼠类动物1463只,平均密度为3.52只/hm^2,其中主要宿主动物长爪沙鼠1235只,密度为2.97只/hm^2。梳检1603只鼠类动物,其中带蚤鼠404只,鼠体染蚤率为25.20%;获鼠体蚤1348匹,平均蚤指数为0.84。共挖鼠巢22个,其中带蚤巢17个,鼠巢染蚤率为77.27%;获巢蚤131匹,平均巢蚤指数为5.95。对所获1603只鼠类动物进行鼠疫病原学剖验,结果判定疫鼠7只,均为长爪沙鼠。对所获581组1479匹蚤类进行鼠疫病原学检验,检出疫蚤5组14匹,其中四子王旗1组3匹;化德县4组11匹。检测鼠类动物血清243份,结果均为阴性。结论内蒙古自治区乌兰察布市鼠疫疫情处于活跃状态,今后应继续加强鼠疫监测,防止人间鼠疫的发生。
Objective To analyze the plague monitoring results in Ulanqab City of Inner Mongolia in 2018,to master the changes in rat density and the prevalence of plague in rats,and provide a basis for scientific prevention and control of plague.Methods According to"The Plague Monitoring Scheme of Inner Mongolia",we surveyed Siziwang Banner,Chahar Right Back Banner,Huade County,and Shangdu County of Ulanqab City from April to November 2018 to monitor the plague.Rat density was surveyed using a one-day bow clamp method;small rodent was surveyed using a 5 m clamping method.Rodents were obtained by sample method,5 m clamping method,daily method,collecting dead animals and the like,and fleas were picked up from the captured rats and rat nest.The rodents and fleas were carried out pathogen detection,the serum of rodents was tested by indirect hemagglutination test.Laboratory test results were analyzed based on the"Diagnostic Criteria for Plague"(WS 279-2008).Results Totally 1463 mice were captured overlapping a monitored area of 416 hm^2,the average rat density was 3.52 per hectare;the number of Meriones unguiculatus was 1235,and the rat density was 2.97 per hectare.Totally 1603 mice were grooming,404 mice with fleas,the flea infected rate was 25.20%,the number of fleas were 1348,and the flea index was 0.84.A total of 22 mouse nests were dug,17 nests with fleas,the flea infected rate was 77.27%,the number of fleas were 131,and the flea index was 5.95.Totally 1603 rodents were checked by etiology,the results showed that 7 plague rats were all Meriones unguiculatus.Totally 1479 fleas of 581 groups were cultured,14 fleas of 5 groups were detected,3 fleas of 1 group in Siziwang Banner,and 11 fleas of 4 groups in Huade County.Totally 243 samples of murine animal serum were tested and the results were all negative.Conclusions The epidemic of plague in Ulanqab City is in an active state,so monitoring should be strengthened in this area to prevent the prevalence of human plague.
