Abstract
Here we report the detection of Candidatus Rickettsia tarasevichiae from tick collected from human patient through DNA amplification. The tick was identified to be Haemaphysalis longicornis. We amplified and sequenced rickettsial citrate synthase gene (gltA), 190_kDa outer protein gene (ompA), and 120_ kDa outer protein gene (ompB). Sequencing results showed that gltA gene and ompA (GenBank accession No. KT899085, KT899079, respectively) shared 100% nucleotide sequence similarities with Candidatus R. tarasevichiae. In addition, ompB gene shared 96% nucleotide sequence similarity with R. canadensis. However, DNA extracted from patient serum showed 98% sequence similarity with R. japonica (AF123713.1). This result implies that H. longicornis ticks harbor both Candidatus R. tarasevichiae and R. japonica.
