摘要: 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。

Abstract: We have investigated the vector of Lyme disease spirochetes and infection rate of residents in the greater Xing-An mountains of Inner Mongolia in May-August 1990. Ixodes persulcatus of Ixodidae is prevailling in this region. Spirochetes were observed in midguts smear by direct immunofluorescence tests. 16 of 40(40 per cent) Ixodes persulcatus contained spirochetes. 19 Isolates were made from 46 group(380 Ⅰ. persulcatus) and these isolates were distinguished between China and USA by monoclonal antibodies. The sera of 308 residents were tested for antibodies against Borrelia burgdorferi (strain B31) by IFA, 41(13.3%) residents were positive. These studies indicate that Ixodes persulcatus is primary vectors that transmit these spirochetes to human and other animal and this region is enlemic area of Lyme disease.
