host associations and seasonal abundance of immature ixodes persulcatus (acari: ixodidae) in a lyme-disease-endemic area in china.ticks of nine small mammal species were studied in an area of endemic lyme disease in hailin county, heilongjiang province, from 1 may to 10 october 1986. the bulk (93%) total small mammal captures were apodemus speciosus (45%), clethrionomys rufocanus (31%), a. agrarius (11%) and eutamias sibiricus; (5%): these host species accounted for 97% of the 162 ticks collected. ixodes persulcatus schulze were most abundant on e. sibiricus (0.64 larvae and 0.08 nymphs/squirrel), and less abundant on a. a ...19911773682
characterization of spirochetes isolated from ticks (ixodes tanuki, ixodes turdus, and ixodes columnae) and comparison of the sequences with those of borrelia burgdorferi sensu lato strains.ixodes persulcatus serves as a tick vector for borrelia garinii and borrelia afzelii in japan; however, unidentified spirochetes have been isolated from other species of ticks. in this study, 13 isolates from ticks (6 from ixodes tanuki, 6 from ixodes turdus, and 1 from ixodes columnae) and 3 isolates from voles (clethrionomys rufocanus) were characterized by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, rrna gene restriction fragment length polymorphism, partial sequencing of the o ...19968779571
genetic diversity of borrelia burgdorferi sensu lato isolated in far eastern russia.one-hundred and fifty-seven borrelia isolated from adult ticks, ixodes persulcatus, and wild rodents, clethrionomys rufocanus and apodemus peninsulae, in the far eastern part of russia were characterized and identified by restriction fragment length polymorphism (rflp) of the 5s-23s rrna intergenic spacer. some isolates showed unique rflp patterns and were determined as borrelia garinii on the basis of a sequence analysis of the intergenic spacer amplicon and reactivity with species-specific mon ...19979310938
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
[preliminary investigation on reservoir hosts of borrelia burgdorferi in china].from 1987 to 1997, the reservoir hosts of borrelia burdorferi(b.b.) were investigated in 16 provinces, municipalities and autonomous regions of china. seroepidemiological findings indicated that cattle, sheep, dogs and rats from forest areas had a high antibody titer for b.b. (b31) with positive rates of 18.18%-32.61%, 17.12%-61.21%, 38.50-60.00% and 41.18%-86.05% respectively. using bsk medium, 20 strains of b.b. were isolated from apodemus agrarius, clethrionomys rufocanus, eutamias sibiricus, ...199912712735
detection of ehrlichial dna in small rodents captured in a woodland area of hokkaido, the northernmost island of japan, where lyme disease is endemic.the ehrlichial gene was detected in small rodents trapped in a lyme disease-endemic area in hokkaido, the northernmost island of japan. primer pairs of 16s rdna targeting the genus ehrlichia and other regions of the 16s rdna specific for e. chaffeensis and e. muris were used for identification. the dna fragment specific for 16s rdna of ehrlichia spp. was detected in 4 of 94 apodemus speciosus mice (positive rate: 4.3%) and 5 of 73 clethrionomys rufocanus bedfordiae mice (positive rate: 6.8%). th ...200516249629
