[new evidence for the detection of ehrlichia and anaplasma in ixodes ticks in russia and kazakhstan].polymerase chain reaction and sequence analysis were used to screen ehrlichia and anaplasma dna in 900 specimens of ixodes ticks of four genera (dermacetor, haemaphysalis, ixodes, and hyalomma) collected on 14 administrative territories of russia and kazakhstan. anaplasma phagocytophilia dna was detected and identified in ixodes persulcatus ticks gathered in the altai and primorye territories. ehrlichia muris dna was genotyped in the i. persulcatus ticks collected in the tyumen, omsk, and novosi ...200415193042
[study of the heterogeneity of 16s rrna gene and groesl operone in the dna samples of anaplasma phagocytophilum, ehrlichia muris, and "candidatus neoehrlichia mikurensis" determined in the ixodes persulcatus ticks in the area of urals, siberia, and far east of russia].a total of 3552 ixodes persulcatus from sverdlovsk, chelyabinsk, novosibirsk, irkutsk regions and khabarovsk territory were examined on the ehrlichia and anaplasma presence by nested pcr based on the 16s rrna gene. both anaplasma phagocytophilum and ehrlichia muris dna were found in i. persulcatus in all studied regions. a. phagocytophilum was detected in 1.3-6.3% of ticks and e. muris - in 2.0-14.1% of ticks. moreover, "candidatus neoehrlichia mikurensis" dna was found in 8 ticks collected in n ...201121786632
[the application of polymerase chain reaction in real-time operation mode to detect dna of agents of human granulocytic anaplasmosis and monocytic erlychiosis].the analysis was applied to detect dna of agents of human granulocytic anaplasmosis and monocytic erlychiosis. the sampling included 109 ticks of ixodes species from novosibirsk oblast and khabarovsk kray and blood samples of 111 mouse-like rodents from omsk oblast. the used techniques included polymerase chain reaction in real-time operation mode with set of reagents "realbest dna anaplasma phagocytophilum/ehrlichia muris, ehrlichia chaffeensis" ("vector-best" novosibirsk) and double round poly ...201223305021
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
