1991年5～6月,我们在四川省南川县调查莱姆病动物宿主,从白腹鼠肾脏分离出1株螺旋体(SR1)。用种和属单克隆抗体对SR1菌株进行间接免疫荧光抗体试验,该菌株与美国B_(31)菌株的单克隆反应基本相似,但外表蛋白抗原并不完全一致,表明该鼠可能是我田南方莱姆病螺旋体的重要动物宿主。从白腹鼠分离出莱姆病螺旋体,在国内外属首次报告。 From May to June 1991, we investigated the host animal of Lyme disease in Nanchuan County, Sichuan Province. One strain of spirochete (SR1) was isolated from the kidney of white-bellied rats. Indirect immunofluorescent antibody test was carried out on the SR1 strain with monoclonal antibodies and monoclonal antibodies. The monoclonal antibody was similar to the monoclonal antibody against the B 31 strain in the United States, but the outer protein antigen was not completely identical, indicating that the rat may be southern An important animal host for Borrelia burgdorferi. Isolated from white-backed mice Lyme disease spirochetes, is the first report at home and abroad.
