First detection and genetic identification of Rickettsia infection in Rhipicephalus sanguineus (Acari: Ixodidae) ticks collected from Southern Taiwan
The prevalence and genetic identity of Rickettsia infection in Rhipicephalus sanguineus sensu lato (s.l.) ticks were determined in Taiwan. In total 1153 ticks were examined for Rickettsia infection by PCR assay targeting the citrate synthase gene (gltA) of Rickettsia . The prevalence of Rickettsia i...

Zusammenfassung: | The prevalence and genetic identity of
Rickettsia
infection in
Rhipicephalus sanguineus
sensu lato (s.l.) ticks were determined in Taiwan. In total 1153 ticks were examined for
Rickettsia
infection by PCR assay targeting the citrate synthase gene (gltA) of
Rickettsia
. The prevalence of
Rickettsia
infection in
R. sanguineus
s.l. ticks with a general infection rate of 2.2%, and was detected in nymph, male and female stages of
R. sanguineus
s.l. ticks with an infection rate of 3.1, 2.0 and 1.1%, respectively. Phylogenetic relationships were analyzed by comparing the gltA sequences obtained from four Taiwan strains and 16 other strains representing 13 genospecies of
Rickettsia
. Phylogenetic analyses reveal that one Taiwan strain was genetically affiliated with the Japan isolate (GRA-1 strain) which belongs to the spotted fever group (
R. parkeri
/
R. honei
) and three Taiwan strains were genetically affiliated with the transitional group of
Rickettsia
(
R. felis
). Intra- and inter-species analysis also indicated the genetic distance (GD) of the Taiwan strains with a lower level of GD |
