我们于1990年5～8月在内蒙大兴安岭,对莱姆病螺旋体的生物媒介和人群感染进行了调查,全沟硬蜱(Ixodes persulcatus)是当地蜱类的优势种,用直接荧光抗体法检查全沟硬蜱的中肠涂片,发现其带菌率为40%;从46组(380只)全沟硬蜱中分离出19株莱姆病螺旋体。分离出的菌株在单克隆反应上与美国菌株不同。用间接荧光抗体法检测308名居民血清,阳性率为13.3%。以上研究证明,大兴安岭是莱姆病疫区,全沟硬蜱是将莱姆病螺旋体传播到人和动物的主要生物媒介。
We conducted a survey of the biological vectors and human infections of Borrelia burgdorferi in Daxing’anling, Inner Mongolia, from May to August 1990. Ixodes persulcatus was the dominant species of ticks in the country and was examined by direct fluorescent antibody In the midgut smear of Ictalurus punctatus, the rate of infection was found to be 40%. Nineteen Lyme disease spirochetes were isolated from 46 ticks (380) Ixodes. The isolated strain is different from the U.S. strain in the monoclonal reaction. Using indirect fluorescent antibody test 308 residents serum, the positive rate was 13.3%. The above study shows that Daxinganling is Lyme disease endemic area, Ixodes Ixodes versicolor is the main biological vector for the transmission of Lyme disease spirochetes to humans and animals.
