Abstract:In order to investigate the infection state of Rickettsia from X. minax at China-Kazakh border,the X. minax were collected,and 17 kDa genes of Rickettsia were tested by PCR,and the sequence was analyed by BLAST and phylogenetic allysied by Mage 6.0. Showed that the positive rate of 17 kDa gene of Rickettsia was 42.86% (3/7) at Alashankou Port. The phylogenetic tree of Rickettsia 17 kDa gene showed that the uncultured Rickettsia sp. was the highest homology with Candidatus Rickettsia senegalensis and R. bellii.In conclusion the X. minax infected Rickettsia at China-Kazakh border.
