１９９０年３月～１９９３年９月，我们对福建省莱姆病疫区的蜱、虻类进行调查。共捕获蜱类１７种、虻类３种，对部份蜱、虻类肠道进行莱姆病病原体的分离与检测，结果从其中的粒形硬蜱（Ｉ．ｇｒａｎｕｌａｔｕｓ）中肠及其吸血宿主鼠类（社鼠和褐家鼠Ｒ．Ｃｏｎｆｕｃｉａｎｕｓ＆Ｒ．ｎｏｒｖｅｇｉｃｕｓ）肾脏共分离出４株莱姆病病原体－伯氏疏螺旋体，从台湾角血蜱（Ｈ．ｃｏｒｎｉｇｅｒａｔａｉｗａｎａ）中肠观察到同样病原体，表明粒形硬蜱和某些血蜱可能是福建莱姆病疫区传播该病的生物媒介。此外，我们还发现因虻类、蜂类叮咬而发生感染的病例，提示莱姆病的传播媒介可能还不仅局限于蜱类．
From March 1990 to September 1993, we investigated the ticks and flies of Lyme disease in Fujian Province. A total of 17 species of ticks and 3 species of 虻 species were collected. The pathogens of Lyme disease were isolated and detected in some intestinal ticks of 蜱 and 虻. The results showed that the pathogens from I.granulatus midgut and its blood-sucking host Four strains of Lyme disease Borrelia burgdorferi were isolated from the kidney of mice (R. Confusianus & R. norvegicus) and the same pathogen was observed from the midgut of H. hornigerataiwana, Ixodes sinensis and some blood-borne ticks may be the biological vectors that transmit the disease in the endemic areas of Lyme disease in Fujian Province. In addition, we also found cases of infections caused by bites and bee bites, suggesting that the carrier of Lyme disease may not only be limited to ticks.
