Abstract: From April to June 1991, investigation of Lyme disease was carried out in the southern part of the Greater Xing-An mountains. The sera of 496 residents were tested for antibodies against Borrelia burgdorferi (strain B31) by indirect immnnofluorescence assay, 38(7.66%) residents were positive. 22 cases of Lyme disease were confirmed by clinical manifestation and serological test. 4 isolates were made from 26 Ixodes persulcatus, These isolates were distinguished between China and USA by monoclonal antibodies. These studies indicate that this region is endemic area of Lyme disease.
