家鼠型流行性出血热鼠间传播因素的调查研究

Study on the factors of transmission of Epidemic Heamorrhagic Fever of domestic-rodent-type among mice

1989年5月,在江苏省家鼠型EHF疫区进行鼠间传播因素调查中,发现鼠密度高的地区,鼠的EHF抗原、抗体阳性率均显著高于鼠密度低的地区;鼠体皮肤破损组鼠的EHF抗原、抗体阳性率显著高于无破损组;鼠肺EHF抗原阳性者,鼠粪EHF抗原阳性率均明显高于胃残留食物EHE抗原阳性率。结合鼠各脏器EHF抗原检测结果分析表明:在家鼠型EHF鼠间传播因素中,以鼠间密切接触和鼠体皮肤破损为主要因素。

The factors of transmission of Epidemic Heamorrhagic Fever (EHF) among mlce were investigated in domestic-rodenttype focus of EHF in fiang su Province in May 1989. It was found that the positive rate of antigen/antibod of EHF in mice in area of high mice density were significantly higher than that of low mice density. Tnar in the group of skin damage were much greater than that of skin disdamage. The positive rate of antigen of EHF in the feces of mice was significantly increased compared with remained food of stomach. The results showed that contacting closely among mice and skin damage were most important factor of transmission in demestic-rodent-type among mice.
