Natural tick-borne encephalitis virus infection among wild small mammals in the southeastern part of western Siberia, Russia.

Infestation of small mammals, including common shrews Sorex araneus L., field mice Apodemus agrarius Pallas, and red voles Clethrionomus rutilus Schreber, with immature Ixodes persulcatus ticks and their infection with tickborne encephalitis virus (TBEV) were studied in the forest-steppe habitat in the vicinity of Novosibirsk, Russia. Larval ticks parasitize all three host species, but virtually all nymphs were found only on field mice and red voles.

Tickborne pathogen detection, Western Siberia, Russia.

Ixodes persulcatus (n = 125) and Dermacentor reticulatus (n = 84) ticks from Western Siberia, Russia, were tested for infection with Borrelia, Anaplasma/Ehrlichia, Bartonella, and Babesia spp. by using nested polymerase chain reaction assays with subsequent sequencing. I.

Babesia DNA detection in canine blood and Dermacentor reticulatus ticks in southwestern Siberia, Russia.

Babesia infection was studied in 21 blood samples of dogs with symptoms of babesiosis and among 72 Dermacentor reticulatus and 70 Ixodes persulcatus ticks from southwestern Siberia, Russia. Babesia DNA was detected by hemi-nested PCR based on the 18S rRNA gene with subsequent direct sequencing. All of the analyzed canine blood samples and three D.

Semi-nested PCR detection of Bartonella henselae in Ixodes persulcatus ticks from Western Siberia, Russia.

Questing adult Ixodes persulcatus ticks from Western Siberia, Russia were tested for infections with Bartonella spp. using seminested PCR assay with primers specific to the groEL gene. The proportion of ticks infected with Bartonella spp.

Characterization of Borrelia burgdorferi sensu lato from Novosibirsk region (West Siberia, Russia) based on direct PCR.

Borrelia burgdorferi sensu lato infecting Ixodes persulcatus ticks near Novosibirsk, Russia were detected using PCR with primers specific to 5S and 23S rRNA genes. Two genospecies, B. afzelii and B.
