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
widespread rickettsia spp. infections in ticks (acari: ixodoidea) in taiwan.ticks are second to mosquitoes as the most important disease vectors, and recent decades have witnessed the emergence of many novel tick-borne rickettsial diseases, but systematic surveys of ticks and tick-borne rickettsioses are generally lacking in asia. we collected and identified ticks from small mammal hosts between 2006 and 2010 in different parts of taiwan. rickettsia spp. infections in ticks were identified by targeting ompb and glta genes with nested polymerase chain reaction. in total, ...201526336223
molecular detection and characterization of spotted fever group rickettsiae in taiwan.rickettsioses are emerging infectious diseases caused by rickettsiae in association with arthropods. we report the detection of spotted fever group rickettsiae (sfgr) in taiwan using molecular methods. phylogenetic analyses of the 17-kd protein and citrate synthase (glta) genes showed that sfgr twkm01 detected in rhipicephalus haemaphysaloides ticks was most similar to rickettsia rhipicephali. three twkm01 isolates were obtained from three individual r. haemaphysaloides ticks. small, intracellul ...200717984347
identification of rickettsia felis in fleas but not ticks on stray cats and dogs and the evidence of rickettsia rhipicephali only in adult stage of rhipicephalus sanguineus and rhipicephalus haemaphysaloides.rickettsia spp. are zoonotic pathogens and mainly transmitted by various arthropod vectors, such as fleas, ticks, and lice. previous epidemiological studies indicated that ectoparasites infested on dogs or cats may be infected by rickettsia spp., and transmit them to human beings accidentally. in this study, the prevalence of rickettsia infection was evaluated using fleas and ticks from stray dogs and cats in taiwan. a total of 158 pools made by 451 cat fleas (ctenocephalides felis) from 37 dogs ...201122000945
