Tickborne Pathogen Detection, Western Siberia, Russia

Ixodes and Dermacentor ticks harbor Borrelia, Anaplasma/Ehrlichia, Bartonella, and Babesia species

PCR Detection of Borrelia burgdorferi Sensu Lato, Tick-Borne Encephalitis Virus, and the Human Granulocytic Ehrlichiosis Agent in Ixodes persulcatus Ticks from Western Siberia, Russia

PCR assays were used to test adult Ixodes persulcatus ticks from Western Siberia, Russia, for Borrelia burgdorferi sensu lato, tick-borne encephalitis virus (TBEV), and the human granulocytic ehrlichiosis (HGE) agent. Of the 150 ticks that were studied, 38% were infected with B. burgdorferi, 46% were infected with TBEV, and 8% were infected with the HGE agent. These three pathogens were distributed in the ticks independently of one another

As a part of the Science Exchange Program between Nagoya University and Russian Academy of Sciences, heligmosomid nematodes of the small mammals captured in the adjacent area of Akademgorodok City, West Siberia, Russia was investigated in summer, 1994. The host materilas of the survey were 27 individuals of the Soricidae and 60 individuals of the Muridae, and its specific names were shown below; Sorex araneus, S. caecutiens, S. isodon, S. minutus, S. tundrensis, Apodemus agrarius, A. peninsulae, Clethrionomys glareolus, C. rufocanus, C. rutilus, Microtus agrestis, M. arvalis, M. gregalis and M. oeconomus. Among them, Longistriata depressa was obtained from S. araneus, S. isodon, S. minutus and S. tundrensis, and Heligmosomoides neopolygyrus was obtained from A. agrarius and A. peninsulae, respectively. However, there was no heligmosomid obtained from the genera Clethrionomys or Microtus. This is the first host record of L. depressa from S. isodon and S. tundrensis, and the locality record of H. neopolygyrus from West Siberia
