| 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 ... | 2007 | 17984347 |
| molecular analysis of ixodes granulatus, a possible vector tick for borrelia burgdorferi sensu lato in taiwan. | the genetic identity of ixodes granulatus ticks was determined for the first time in taiwan. the phylogenetic relationships were analyzed by comparing the sequences of mitochondrial 16s ribosomal dna gene obtained from 19 strains of ticks representing seven species of ixodes and two outgroup species (rhipicephalus sanguineus and haemaphysalis inermis). four major clades could be easily distinguished by neighbour-joining analysis and were congruent by maximum-parsimony method. all these i. granul ... | 2009 | 19184580 |
| bartonella and babesia infections in cattle and their ticks in taiwan. | bartonella and babesia infections and the association with cattle breed and age as well as tick species infesting selected cattle herds in taiwan were investigated. blood samples were collected from 518 dairy cows and 59 beef cattle on 14 farms and 415 ticks were collected from these animals or in a field. bartonella and babesia species were isolated and/or detected in the cattle blood samples and from a selected subset (n=254) of the ticks either by culture or dna extraction, pcr testing and dn ... | 2010 | 21194750 |
| 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 ... | 2011 | 21223345 |
| 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 ... | 2011 | 22000945 |
