目的：广泛调查我国动物莱姆病分布情况。方法：血清流行病学和病原学研究。结果：１９８７～１９９７年间，牛、羊、狗、野兔和８种野鼠有莱姆病的感染存在，其中牛、羊、狗和野鼠的感染率分别为１８．１８％～３２．６１％、１７．１２％～６１．２１％、３８．５％～６０．００％和４１．１８％～８６．０５％；从黑线姬鼠和白腹巨鼠的胎鼠分离到莱姆病螺旋体，证实莱姆病螺旋体可通过胎盘垂直传播。９种蜱的中肠携带莱姆病螺旋体，带菌率以全沟硬蜱、二棘血蜱和粒形硬蜱为高，分别为２０．００％～４５．００％、１６．００％～４０．００％和２４．００％。从华南兔、８种野鼠和８种蜱分离出１２８株莱姆病螺旋体。证实黑线姬鼠和棕背是中国莱姆病螺旋体的重要储存宿主；多种蜱的中肠内携带莱姆病螺旋体，我国北方林区莱姆病螺旋体的主要生物媒介是全沟硬蜱，南方林区二棘血蜱和粒形硬蜱是重要的生物媒介。结论：我国动物莱姆病广泛存在
Objective: To investigate the distribution of animal Lyme disease in our country. Methods: Seroepidemiology and etiology research. Results: In 1987 ~ 1997, there were some Lyme disease infections in cattle, sheep, dogs, hares and eight kinds of wild animals. The infection rates of cattle, sheep, dogs and voles were 18.18% ~ 32.61%, 17 .12% -61.21%, 38.5% -60.00% and 41.18% -86.05% respectively. Lyme disease spirochetes were isolated from fetus of Apodemus agrarius and white gazelle Lyme disease spirochetes can be transmitted vertically through the placenta. The nine species of ticks carried Borrelia burgdorferi in the midgut, with rates of 20.00% -45.00%, 16.00% -40 .00% and 24.00%. 128 Lyme disease spirochetes were isolated from South China rabbits, 8 wild species and 8 ticks. It was confirmed that Apodemus agrarius and Pelteobagrus fulvidraco were important storage hosts for Borrelia burgdorferi in China. A variety of ticks carried Borrelia burgdorferi in the midgut. The main biological vector of Borrelia burgdorferi in northern China was Myrmeca Ixodes In the southern forest area Twigged tick and Ixodes scabi are important biological vectors. Conclusion: Lyme disease is widespread in our country
