Abstract
- A total of 190 ticks collected from the Chungju area of Korea was examined for the presence of Spotted Fever Group(SFG) Rickettsia using a PCR assay. Twenty-five (13.2%) Haemaphysalis ticks were found positive of the groEL gene of SFG Rickettsia. The prevalence rate of R. japonica in these 25 Haemaphysalis ticks was 72% (18 out of 25 SFG Rickettsia). The prevalence rate of R. conorii and new SFG rickettsia in these 25 Haemaphysalis ticks was 4% (1 out of 25 SFG Rickettsia) and 24% (6 out of 25 SFG Rickettsia), respectively. These results suggest that R. japonica was the highest infection frequency among in Haemaphysalis ticks SFG Rickettsia, and that R. conorii and new SFG Rickettsia are also present in the Chungju area.
