Abstract

Objective To investigate the constitution,density changes and carrier rate about Yersinia pestis of rodents in plague foci,and to provide the scientific evidence for plague prevention.Methods According to the program of national monitoring plague,two survey procedures,namely quadrat of single-ha for 24 h and 5 m mouse jam,were used to monitor the host animals; culture and identification of Yersinia pestis in liver or spleen of the experimental animals was carried out by using self-made medium in the north of Beiyuanzi village in Dingbian town Shaanxi province.Results One hundred twelve rodents were captured using the first procedures and the rodent average density was 8.62 ind./hm2 and six species of rodents were found namely Meriones unguiculatus ( 100 individuals),Microtusfortis(5 individuals),Ochotona daurica(3 individuals),Meriones meridianus (2 individuals),Mus musculus Linnaeus (1 individual) and Cricetulus barabensis (1 individual).One hundred seventy-three field mouses were captured using the second procedures including Mus musculus Linnaeus (136 individuals),Cricetulus barabensis (36 individuals),and Microtus fortis ( 1 individual ).Among them,Microtus fortis was found in the salt marshes in the southern edge of Ordos Plateau steppe in plague area of Dingbian county.Yersinia pestis was not identified in all animals.Conclusions Microtus fortis is found in natural foci of plague in Shaanxi province for the first time,and a new geographic region was found.Its epidemiological significance needs further study. Key words: Yersinia pestis ; Epidemiology; Microtus fortis

2010年陕西省定边镇鼠疫自然疫源地东方田鼠生态调查

目的了解鼠疫疫源地鼠类鼠疫耶尔森菌构成、密度变化及携带率，为鼠疫防控提供科学依据。方法根据国家鼠疫监测规划，采用单公顷24 h样方法和5 m鼠笼法监测宿主动物;在陕西省定边镇北院子村北部用自制培养基对实验动物肝脏或脾脏鼠疫菌进行培养鉴定。结果第1步共捕获鼠类112只，平均鼠密度为8.62只/hm2，共捕获爪鼠(100只)、小兔(5只)、达乌尔沙鼠(3只)、子午沙鼠(2只)、林奈小家鼠(1只)、barabensis环鼠(1只)6种。第二种方法共捕获野鼠173只，其中林奈小家鼠136只，巴拉贝仓鼠36只，东方田鼠1只。其中，在定边县鼠疫区鄂尔多斯高原草原南缘盐沼中发现东方田鼠。没有在所有动物中发现鼠疫杆菌。结论在陕西省鼠疫自然疫源地首次发现东方田鼠，并发现了一个新的地理区域。其流行病学意义有待进一步研究。关键词:鼠疫耶尔森菌;流行病学;草原富通银行
