prevalence of lyme borrelia in ticks, especially ixodes persulcatus (acari: ixodidae), in central and western japan.prevalence of lyme borrelia in unfed ticks was surveyed in central and western japan during spring from 1991 to 1993. the tick fauna was diverse; ticks obtained consisted of four genera and more than 12 identified species, and both southern and northern species coexist with altitudinal separation. midguts of ticks were cultured in bsk medium for spirochetal isolation. borrelia-positive rates for adults of both a common species, ixodes ovatus neumann, and a northern species, ixodes persulcatus sc ...19948057323
characterization of borrelia spp. isolated from the tick, ixodes tanuki and small rodents in japan.spirochetes were isolated from the tick, ixodes tanuki, as well as wood mice (apodemus speciosus) and voles (clethrionomys rufocanus and eothenomys smithii), caught in fukui, tokushima, and hokkaido, japan, from 1991 to 1993. spirochetes were characterized on the basis of protein profiles, reactivities with monoclonal antibodies (mabs), outer surface protein a gene (ospa) and outer surface protein b gene (ospb) amplification analysis, rrna gene and flagellin gene restriction fragment length poly ...19969359053
molecular evidence of the dispersal of lyme disease borrelia from the asian continent to japan via migratory birds.based on specific sequencing, we found that a borrelia garinii strain from a rodent in fukui prefecture, japan was highly similar to the unique borrelia strains (pattern r'/r) isolated in northeastern china and korea, and to strains from ticks feeding on migratory birds in fukui prefecture. these findings indicate that the borrelia with this unique pattern may be locally naturalized to the epizootic transmission cycle in japan, and that borrelia is dispersed from the asian continent to japan via ...200515973014
