1999年 5月 2 5日～ 9月 15日在精河县南山鼠疫自然疫源地 ,继续开展人类鼠疫和动物鼠疫监测工作。长尾黄鼠染蚤率为 95 .5 % ,蚤指数为 6 .5 ;检验长尾黄鼠 42 4份 ,分离出鼠疫菌 2株 ,阳性率为 0 .5 % ;检验长尾黄鼠血清 2 86份 ,阳性 2 1份 ,阳性率为 7.3%。监测结果表明 ,该疫源地黄鼠体外寄生蚤、蚤指数、病原学和血清学阳性率与历年同期水平相近 ,若无人为因素干扰 ,该地区仍会有较高强度的鼠疫动物病流行 ,应加强监测力度 ,防止人类鼠疫发生。
From May 25 to September 15, 1999, the Plague and animal plague surveillance in the natural plague area of Nanshan in Jinghe County was continued. Long-tailed kangaroo flea infection rate of 95.5%, flea index of 6.5; test 42 long-tailed Salmonella, Yersinia pestis isolated 2 strains, the positive rate was 0.5%; test long-tailed Salmonella serum 2 86, 21 positive, the positive rate was 7.3%. The monitoring results showed that the ectoparasitides, flea index, etiological and seroprevalence of chrysalis in this foci were similar to the same period over the previous years. If there is no interference from other factors, there will still be epidemics of the plague animals with high intensity in this area. Strengthen monitoring efforts to prevent the occurrence of human plague.
