small mammals as reservoir hosts for borrelia in russia.in 1992-1993, a total of 29 isolates of borrelia were obtained from small mammals captured in taiga forests of the perm' region: 26 isolates were obtained from clethrionomus glareolus and one each from c. rufocanus, microtus oeconomus, and apodemus sylvaticus. isolation of borrelia was performed by plating the animal material on bsk-ii medium. most isolates (86.2%) were obtained from the urinary bladder, the rest from the heart and spleen. according to the results of ifa with a set of monoclonal ...19957549164
[the isolation of borrelia from the tick ixodes trianguliceps (ixodidae) and the possible significance of this species in the epizootiology of ixodid tick-borne borrelioses].ixodes trianguliceps is a common tick species of the eurasian forest zone. these ticks live probably in natural foci of ixodid tick-borne borrelioses (itbb) from western europe to transbaikalia, but their role in circulation of corresponding pathogens remains unclear. this study was performed in a natural itbb focus located in the perm region of russia (near the urals), where borrelia garinii and b. afzelii circulate and i. persulcatus serves as their main vector. in july-august of 1994, 296 sma ...19968975209
risk for human tick-borne encephalitis, borrelioses, and double infection in the pre-ural region of russia.we assessed the risk for human tick-borne encephalitis (tbe), ixodid tick-borne borrelioses, and double infection from 1994 to 1998 in perm, which has among the highest rates of reported cases in russia. we studied 3,473 unfed adult ixodes persulcatus ticks collected from vegetation in natural foci and 62,816 ticks removed from humans. tbe virus and borrelia may coexist in ticks.200111384529
[long-term dynamics of the epizootic process in natural foci of ixodid tick borreliosis in mountain taiga forests of the middle ural].during eleven spring-summer seasons (1992-2002), the dynamics of the epizootic process in natural foci of ixodid tick-borne borrelioses (itbb) were studied in taiga forests of the middle ural (perm province, russia). in these foci, borrelia garinii and b. afzelii circulate, and their main vector is the ixodes persulcatus tick. main parameters of the epizootic process were calculated for each season. in four seasons (1993, 1996, 1999 and 2002), the parameters characterizing the abundance of unfed ...200415174388
[spontaneous mixed infection in rodents with borrelia and leptospira].this study was performed in a natural itbb focus located in perm' region of russia. in 1993-1995, 73 root voles (microtus oeconomus), collected in the forests, were examined by means of inoculation of internal organs on bsk-ii medium. borrelia were found in 13 animals (17.8%). according to the results in rlfp analysis 11 isolates were classified as b. garinii, 1 as b. afzelii and 1 as mixture of b. garinii and b. afzelii. in one case leptospira, which was identified by pfge analysis as grippotyp ...19969026677
[antibacterial therapy as a means of preventing ixodid tick-borne borreliosis].a special epidemiological experiment to prevent borreliosis in persons bitten by infected ticks was performed in 1992-1994 in the russia's perm region where borrelia garinii and b.afzelii circulate, and ixodes persulcatus tick is the sole vector transmitting these pathogens to human beings. adult ticks were removed from the bodies of persons who had referred to health facilities for first aid. vital preparations were made from the material obtained from the gut of each tick and examined microsco ...19968926931
prevention of borreliosis in persons bitten by infected ticks.a study on prevention of borreliosis in humans bitten by infected ticks was performed in 1992-1994 in the perm' region of russia. adult ixodes persulcatus ticks were removed from the study subjects, and live preparations made from the material obtained from the gut of each tick were microscopically analyzed (up to 250 microscopic fields per preparation). persons were divided into experimental and control groups (261 and 97 persons, respectively). the experimental group received doxycycline (100 ...19968740120
[the clinical picture and course of the nonerythematous form of ixodid tick-borne borreliosis].the territory of the perm region is highly endemic in ixodes (b. garinii and b. afzelii)-borne borreliosis. the clinical manifestations of erythema-less ixodes-borne borreliosis were studied in the 1991-1994 epidemiological seasons. a total of 54 patients were examined in the acute stage of infection and 4-6 months later. there were common symptoms of damage to the central nervous system in early infection and pronounced signs of damage to the central and peripheral nervous systems in the late p ...19957476673
[etiological structure of complex ixodes tickborne borreliosis natural foci of southern taiga].89 primary isolates of b. garinii and 72 b. afzelii from different developmental phases of i. persulcatus, i. trianguliceps and form small mammalian hosts of borrelia were obtained at an area of ca. 30 km2 located in low-mountain southern taiga forests (perm region). the area provides home for two borrelia species (b. garinii and b. afzeli) and their natural carrier ixodes persulcatus. 23 isolate of b.garnii were obtained from skin biopsies and blood samples taken in patients with borreliosis. t ...201122168033
[isolation of tick-borne borreliosis agent from blood of patients].during spring-autumn period of 2006 borrelia were isolated for the first time in russia from blood of 79 patients treated in perm city clinical hospital for infectious diseases no. 1 with diagnosis "tickborne borreliosis, manifestive form with migrating erythema, localized stage". ten primary isolates (12.7% of total seeded samples) were obtained by seeding plasma samples on the bsk medium. their subsequent identification by polymerase chain reaction-restriction fragments length polymorphism rev ...200919340967
[risk of human infection with ixodes tick-borne relapsing fever in different regional subzones of the perm region].serological and epidemiological surveys covered 2407 persons in 20 populated localities situated in all large geographical and regional subdivisions (subzones) in the perm region. indirect immunofluorescence tests revealed serum immunoglobulins to borrelia burgdorferi sensu lato. antibodies in 1:40 or higher dilution were found in nearly 5 to 11% of the dwellers of localities in the subzones of south taiga, coniferous broad-leaved forests, and forest steppe; about 3-7% and 1-6% of them were pres ...200212224266
