目的了解定边县鼠疫疫区周围地区宿主动物及媒介蚤分布现状。方法以村为单位,通过走访群众和实地考察,了解鼠类分布概况;采用公顷夹日法在长爪沙鼠分布区调查鼠密度;采用5米夹笼法调查夜行鼠密度;采集捕获鼠体表寄生蚤进行种类鉴定;采集鼠血清检测F1抗体。结果石洞沟、贺圈、白泥井3乡(镇)局部地区有长爪沙鼠分布,平均密度为10.00只/公顷,最高密度为66只/公顷;长爪沙鼠染蚤率为19.90%,蚤指数为0.31,秃病蚤为优势种。结论定边县鼠疫疫区周围地区有可能发生动物鼠疫流行,应加强该地区监测工作。
Objective To understand the distribution of host animals and media fleas around the plague area in Dingbian County. Methods Using the village as a unit, the distribution of rodent species was investigated through visiting the masses and the field investigation. The density of rats was investigated by the method of hectare and sand method. The density of nocturnal rats was investigated by 5-meter cage method. Table parasitic fleas species identification; collected serum F1 antibody detection. Results In Shidonggou, Hequan and Baitaijing 3 townships, the gerbil was distributed in the local area with the average density of 10.00 / ha and the highest density of 66 germplasms per hectare. The rate of flea infection was 19.90 %, Flea index of 0.31, bald flea dominant species. Conclusion There is a possibility of plague epidemic in the area around the plague epidemic area in Dingbian County. Monitoring in this area should be strengthened.
