本文指出,在EHF高发疫区二个乡的五个自然村,按每15m~2放夹1个进行捕鼠,标记捕鼠点的位置和栖息场所,用荧光抗体技术对捕获的每只小兽作EHF病毒抗原、抗体检测,结果捕获6种小兽,查到褐家鼠、小家鼠携带EHF病毒抗原或抗体,褐家鼠为优势种,且病毒感染率最高。从家鼠EHF病毒感染的季节分布看带病毒率,以6月份最高,EHF抗体阳性率以2月份最高,褐家鼠EHF病毒感染率平屋高于楼屋,EHF病毒感染鼠在居民区内的空间分布比较广泛。但在感染率高的地方有相对集中,这些相对集中的地点未感染鼠的密度也比较高。
This paper points out that in five natural villages in two townships of EHF high incidence area, the rats are trapped at a distance of 15m ~ 2 and the location and habitat of the trapping spots are marked. Fluorescent antibody technology is applied to capture each captured small beast For EHF virus antigen, antibody detection, the results captured 6 small animals, found Rattus norvegicus, Mus musculus carrying EHF virus antigen or antibody, Rattus norvegicus as the dominant species, and the highest virus infection rate. From the seasonal distribution of EHF virus infection in house mice to see with the virus rate, the highest in June, the highest positive rate of EHF antibody in February, Rattus norvegicus EHF virus infection rate flat housing above the house, EHF virus infection in the residential area Spatial distribution is more extensive. However, there is relative concentration in areas with high infection rates. The density of uninfected mice in these relatively concentrated sites is also relatively high.
