| [occurrence of tsutsugamushi disease infection by orientia tsutsugamushi, kawasaki serotype, in yamagata prefecture, japan]. | of 95 tsutsugamushi disease case occurring in yamagata prefecture from 1999 to 2006, four-all women-involved the o. tsutsugamushi kawasaki serotype. the three major symptoms were fever, exanthema, and eschar present from mid-october to early november. serodiagnosis by indirect immunofluoresence assay showed elevated igg and igm antibody titers against the kawasaki serotype antigen, with igm higher than igg. nested pcr detected 56-kda dna in three of the cases. dna was amplified in kawasaki-speci ... | 2009 | 19860249 |
| [sequence analysis subtyping of the 56-kda protein-encoding gene of karp-type orientia tsutsugamushi isolated in scrub typhus cases]. | to determine the karp-type orientia tsutsugamushi subtype in northern japan, i.e., yamagata, niigata, and akita prefectures, we analyzed the partial nucleotide sequence of the 56-kda protein-encoding gene of 30 isolates from scrub typhus cases. based on sequencing results, we classified isolates into two groups of 27 and 3 isolates. nucleotide sequences of 27 isolates were homologous to the yeo-joo strain, classified as a jp-1 subtype. the three isolates were each homologous to a stain of cmm1, ... | 2011 | 22250452 |
| meteorological factors affecting scrub typhus occurrence: a retrospective study of yamagata prefecture, japan, 1984-2014. | climate change, by its influence on the ecology of vectors might affect the occurrence of vector-borne diseases. this study examines the effects of meteorological factors in japan on the occurrence of scrub typhus, a mite-borne zoonosis caused by orientia tsutsugamushi. using negative binomial regression, we analysed the relationships between meteorological factors (including temperature, rainfall, snowfall) and spring-early summer cases of scrub typhus in yamagata prefecture, japan, during 1984 ... | 2017 | 27788693 |
| proposed vector candidate: leptotrombidium palpale for shimokoshi type orientia tsutsugamushi. | to identify the vector species for shimokoshi type orientia tsutsugamushi, a survey of larval trombiculid mites was conducted in yamagata prefecture, japan from april to may 2012. in all, 2889 larval trombiculid mites were obtained from 21 apodemus speciosus rodent hosts, 2600 of which were morphologically classified into eight species in three genera. after screening of o. tsutsugamushi dna in individual larval trombiculid mites using real-time pcr targeting the 16s ribosomal rna gene, serotype ... | 2013 | 23253042 |
