[the preliminary results of an ecological epidemiological study of lyme disease in western siberia].studies of ixodes persulcatus ticks in omsk, kurgan, and novosibirsk regions revealed natural foci of lyme's disease. vector infection rate varied from 21 to 23.5% in the omsk region, from 30 to 52.9% in the kurgan region, and from 15 to 58.3% in the novosibirsk region. serologic screening of inpatients hospitalized during the epidemic season of 1991 with suspected tick-borne encephalitis and lyme's disease confirmed the latter condition in 10.8% of the examinees in the omsk and in 10% in the ku ...19937968805
[detection of dna of borrelia circulating in novosibirsk region].detection of dna of borrelia burgdorferi sensu lato was performed by pcr in taiga ticks ixodes persulcatus, in blood samples and skin bioptates of small forest mammals, and in blood and urine samples of humans after attaching of ticks events. in novosibirsk region both in natural reservoir and in patients with ixodes ticks-borne borreliosis dna of borrelia garinii and borrelia afzelii are detected. dna of these borrelia were detected in 8 from 72 of taiga ticks, in 36 from 298 of blood and skin ...200617297875
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. garinii, were identified by the pcr-based restriction fragment length polymorphism analysis with tru9-i restriction endonuclease. comparison of the corresponding nucleotide sequences revealed considerable diversity of the 5s-23s intergenic spacer structure among b. garinii.200314758874
detection and genetic characterization of a wide range of infectious agents in ixodes pavlovskyi ticks in western siberia, russia.the ixodes pavlovskyi tick species, a member of the i. persulcatus/i. ricinus group, was discovered in the middle of the 20(th) century in the russian far east. limited data have been reported on the detection of infectious agents in this tick species. the aim of this study was to investigate the prevalence and genetic variability of a wide range of infectious agents in i. pavlovskyi ticks collected in their traditional and recently invaded habitats, the altai mountains and novosibirsk province, ...201728545549
