Abstract

The potential role of ticks as vectors of Bartonella species has recently been suggested. In this study, we investigated the presence of Bartonella species in 271 ticks removed from humans [...]

Abstract

We collected 209 Ixodes persulcatusticks in various regions of Russia, including the southern Urals and western and eastern Siberia. Using PCR amplification and sequencing of the citrate synthase-encoding gene (gltA), we detected a new rickettsial genotype, which we named 'Candidatus Rickettsia tarasevichiae.' This bacterium was found in 9.27, 10.0, and 20.5 of the ticks collected in western Siberia, eastern Siberia, and the southern Urals, respectively. 'Candidatus Rickettsia tarasevichiae' exhibited a 98 and 96 nucleotide sequence homology, with the 16S rDNA and gltA sequence, respectively, of R. canadensis, a rickettsia previously only found in Haemaphysalis leporispalustristicks in North America. The phylogenetic analysis of 'Candidatus Rickettsia tarasevichiae' and other Rickettsiaspecies allowed the creation of a new cluster with high bootstrap values within the Rickettsiagenus involving this rickettsia, R. canadensis, and three uncultured rickettsiae from plant insects.

15. Detection of a Rickettsia Closely Related to Rickettsia aeschlimannii, “Rickettsia heilongjiangensis,” Rickettsiasp. Strain RpA4, and Ehrlichia murisin Ticks Collected in Russia and Kazakhstan

Abstract

ABSTRACTUsing PCR, we screened 411 ticks from four genera collected in Russia and Kazakhstan for the presence of rickettsiae and ehrlichiae. In Russia, we detected “Rickettsia heilongjiangensis,” Rickettsiasp. strain RpA4, and Ehrlichia muris. In Kazakhstan, we detected Rickettsiasp. strain RpA4 and a rickettsia closely related to Rickettsia aeschlimannii. These agents should be considered in a differential diagnosis of tick-borne infections in these areas.
