seroepidemiology of hantaan virus infection in order to investigate the infection rate of hantaan virus in taiwan, a total of 6,536 human serum samples were collected from residents, selected by stratified random sampling, from 19 townships covering four different ethnic groups: aborigines, fukien taiwanese, hakka taiwanese, and mainland chinese. serum samples were screened for hantaan virus antibodies by indirect immunofluorescence. the prototype hantaan virus (76/118)-infected vero e6 cells were used as the viral antigen for the antibod ...19968950687
characterization and identification of borrelia isolates as borrelia valaisiana in taiwan and kinmen islands.eleven pure cultures of borrelia from 3 species of wild rodents (apodemus agrarius, mus formosanus, rattus losea) captured in taichung, located in the center of taiwan island, and on kinmen island were characterized. five isolates showed restriction fragment length polymorphism (rflp) patterns of 5s-23s rrna gene intergenic spacer sequences identical to those of strains 5mt and 10mt, identified as borrelia valaisiana, which were isolated in the southern tip of south korea. although the remaining ...200011220673
detection of kobe-type babesia microti associated with japanese human babesiosis in field rodents in central taiwan and southeastern mainland china.field rodent surveys for babesia infection were performed from 2002 to 2005 in the vicinities of human babesiosis occurrences in taiwan and mainland china. babesia microti was identified by microscopical examination and/or pcr in 1 rattus coxinga and 1 crocidura horsfieldii in central taiwan and in 13 niviventer confucianus and 1 apodemus agrarius in zhejiang and fujian provinces of southeastern china. of 15 b. microti samples detected by pcr, all except 1 were shown to be the kobe-type, the aet ...200818413002
variation within and among host species in engorgement of larval trombiculid mites.we recovered larval trombiculid mites (i.e. chiggers), vectors of scrub typhus, from small mammal hosts in taiwan, and compared the relative degree of engorgement (rde) of the dominant chigger (leptotrombidium imphalum) from different hosts. naturally occurring chiggers recovered from rattus losea and bandicota indica were 1·4x and 1·3x as engorged as those from apodemus agrarius. within each host species, rde was negatively related to chigger loads, but was mostly unrelated to gender or to body ...201020946695
identification of potential hosts and vectors of scrub typhus and tick-borne spotted fever group rickettsiae in eastern taiwan.scrub typhus and tick-borne spotted fever group (sfg) rickettsioses are transmitted by chiggers (larval trombiculid mites) and hard ticks, respectively. we assessed exposure to these disease vectors by extensively sampling both chiggers and ticks and their small mammal hosts in eastern taiwan during 2007 and 2008. the striped field mouse apodemus agrarius pallas (rodentia: muridae) was the most common of the small mammals (36.1% of 1393 captures) and presented the highest rate of infestation wit ...201121223345
detection of anaplasma phagocytophilum and anaplasma bovis in small wild mammals from taichung and kinmen island, taiwan.a total of 138 animals from 7 species (apodemus agrarius, bandicota indica, crocidura suaveolens, mus caroli, mus formosanus, rattus losea, and suncus murinus) captured in taichung, located in central taiwan, and kinmen island, an island off the shore of china, were examined for the presence of anaplasma phagocytophilum. the presence of the bacteria, which causes human granulocytic anaplasmosis, was examined by nested pcr targeting the16s rdna. twelve animals (8.7%) from m. caroli and r. losea, ...201424647253
cascading effect of economic globalization on human risks of scrub typhus and tick-borne rickettsial diseases.the increase in global travel and trade has facilitated the dissemination of disease vectors. globalization can also indirectly affect vector-borne diseases through the liberalization of cross-border trade, which has far-reaching, worldwide effects on agricultural practices and may in turn influence vectors through the modification of the ecological landscape. while the cascading effect of economic globalization on vector-borne diseases, sometimes acting synergistically with regional agricultura ...201223092017
detection of rickettsia spp. and host and habitat associations of fleas (siphonaptera) in eastern taiwan.rickettsia typhi and rickettsia felis (rickettsiales: rickettsiaceae) are two rickettsiae principally transmitted by fleas, but the detection of either pathogen has rarely been attempted in taiwan. of 2048 small mammals trapped in eastern taiwan, apodemus agrarius pallas (24.5%) and mus caroli bonhote (24.4%) (both: rodentia: muridae) were the most abundant, and m. caroli hosted the highest proportion of fleas (63.9% of 330 fleas). two flea species were identified: stivalius aporus jordan and ro ...201222390200
