Isolation And Studies On Some Biological Properties Of Borrelia Burgdorferi From Cattle And Sheep In Xilingole Distrct Of Inner Mongolia

2000-2001,studies of Lyme disease were carried out in XiLingole disfrict of Inner Mongolia . 1800 ticks were collected from cattle -. sheep and grass. 7. 5%(6/80)ticks contained spirochetes using direct immuno fluorescence examination 2%(2/100) ticks contained spirochetes using darkfield microscope. 1 Strain of Borrelia burgdorferi was isolated from 520 ticks and named Mu1. It can react with monoclonal antibody I~I5332 and H9724, but can not react with H6931, The results Showed that the isolated spirochetes was lyme disease spirochetes . The serum epidemiological investigation using IFA. confirmed that the average infective rates were respecfively 1O%(1/10) and 20%(1/5) in cattle and rats , and were higher than that in residents (7.09%).
