摘要
目的分析宁夏泾源县鼠种构成、密度、带毒率,为肾综合征出血热防治提供科学依据。方法采用多阶段随机抽样方法,从该县所辖的7个乡(镇)中随机抽取3个乡镇作为一级抽样单位,每个乡镇随机抽取4个行政村作为二级抽样单位,共抽得12个行政村;在所抽得行政村的居民区及野外进行鼠种构成、密度、带毒率调查。结果鼠种构成中,居民区以褐家鼠为优势鼠种,占55.6%;野外以灰仓鼠为优势鼠种,占53.7%。居民区鼠密度1.60%,野外1.63%,总鼠密度1.62%。不同生境鼠密度差别无统计学意义(P>0.05)。9月鼠密度0.80%,10月鼠密度1.89%;不同月份鼠密度差别有统计学意义(P<0.05)。59份鼠肺、血标本肾综合征出血热抗原、抗体检测均为阴性。结论虽然宁夏泾源县鼠密度很低、带毒未检出,但应继续加强鼠间疫情监测,防止疫情反弹。
Objective To analyze the species,density and virus rates of rodents of Jingyuan county.Methods Multi-stage randomly sampling methods were used.Three towns were selected from 7 towns as one sampling unit,12 villages were selected from 3 towns as two sampling unit.The species,density of rodents were investigated by trap-night method.Immunofluorescence technique and indirect ELISA method were used to detect the HFRS virus antigen and antibody.Results The dominant species was Rattus norvegicus（55.6%） at residential area and Cricetulus migratorius in the field （53.7%）. The total rodents density was 1.62%, the residential area was 1.60% while the field was 1.63%. There were no difference in different ecological environments （P 〉 0.05）. The rodent＇s density was higher in October than that in September. There was a significant difference in different months （ P 〈 0. 05 ）. All of the lung tissue and blood samples were negative from the test. Conclusion Though the rodent density and the harttavirus -carrying rate were lower, we should strengthen surveillance to control the rebound of HFRS.
