Molecular Detection and Characterization of Spotted Fever Group Rickettsiae in Taiwan

Abstract: 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, intracellular, coccobacill… Show more

“…1,2 Since then, the bacterium has been reported infecting a number of invertebrate species, including fleas, mosquitoes, ticks, mites, and booklice. [3][4][5][6][7][8] Despite an apparent broad host range, the majority of the literature reports of R. felis have been on fleas of the genus Ctenocephalides; namely, C. felis felis and Ctenocephalides canis collected from domestic dogs and cats. [9][10][11][12] In Brazil, R. felis was reported infecting Ctenocephalides fleas in the states of Sã o Paulo, Minas Gerais, and Rio de Janeiro, all in the Southeastern region of the country.…”

“…Laboratory studies revealed their role in the transmission of Rickettsia (Hsu et al, 2011). Tsui et al, (2007) detected spotted fever group rickettsial organism in R. haemaphysaloides using molecular methods in Taiwan. Experimental transtadial transmission of Babesia microti through R. haemaphysaloides in southern China was also reported (Li et al, 2016).…”

“…Although there are no known human cases of infections caused by spotted fever group (SFG) rickettsiae in Taiwan, novel strains of SFG rickettsiae have been isolated as recently described (6,7). In addition, evidence for R. felis infections in cat and cat fl ea populations has been identifi ed by using immunofl uorescence assay (IFA), PCR, and organism isolation (K.-H.Tsai et al, unpub.…”
