prevalence of antibodies to borrelia spirochetes among wild small rodents in central and western japan.field rodents serve as a reservoir for lyme disease spirochetes. to evaluate the antibody responses of rodents against different borrelia species in relation to fauna of vector ticks feeding on them, we examined 272 sera of wild rodents, apodemus speciosus, a. argenteus, and eothenomys smithii, obtained in 27 locations in central and western japan from 1981 to 1994. as to prevalences by rodent species using immunoperoxidase test, a. speciosus, a. argenteus and e. smithii showed 29.4%, 11.6% and ...19958551974
distribution of borrelia species associated with lyme disease in the subalpine forests of nagano prefecture, japan.we surveyed the natural distribution of borrelia species associated with lyme disease in the subalpine forests of nagano prefecture, japan, during 1993-94. tick-derived isolates (n = 112) from ixodes persulcatus and rodent-derived isolates (n = 55) from apodemus argenteus, apodemus speciosus, eothenomys andersoni, eothenomys smithii, and microtus montebelli were classified by rrna gene restriction fragment length polymorphism analysis (rflp ribotyping). ribotype group iv (an intraspecific varian ...19968709867
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
location and ultrastructure of borrelia japonica in naturally infected ixodes ovatus and small mammals.the internal organs of ixodes ovatus and the ears of wild rodents (apodemus speciosus, eothenomys smithii) and an insectivore (crocidura dsinezumi) were cultured to isolate borreliae; positive samples were examined for the distribution and dissemination of spirochetes in the host tissues using electron microscopy. seven isolates were derived from the unfed ticks and the three species of mammals. these isolates were identified as borrelia japonica judging from the outer surface protein profile us ...19979087963
