鱼台县1984～85年室内大面积多次灭鼠(每年3、5、11月各一次),与未灭鼠的金乡县比较,在鼠种构成上具有高度显著性差别,即:灭鼠前以褐家鼠为绝对优势种,灭鼠后褐家鼠密度大幅度下降,小家鼠则成为优势鼠种,黑线姬鼠亦数倍上升,使鼠种带病毒率卞降。通过疫情分析可见,经长期大面积室内灭鼠后,鼠种构成发生变化,可减轻EHF的流行强度,降低发病率,对有效地控制家鼠型EHF的流行具有重要意义。
Large-scale indoor rodent control in 1984-85 in Yutai County (once every year in March, May and November) compared with that of Jinxiang County did not eradicate the mouse species, with highly significant difference Rattus norvegicus is the predominant species before the mouse. The density of Rattus norvegicus is significantly decreased after rodent exacerbation, while the Mus musculus becomes predominant species. Through the epidemic analysis shows that after long-term large-scale indoor rodent control rats species composition changes can reduce the intensity of EHF epidemic and reduce the incidence of EHF to effectively control the epidemic of home-based mouse is of great significance.
