| incidence of tick-bite in man in aland islands: reference to the spread of lyme borreliosis. | the common tick ixodes ricinus is a vector both for the virus of tick-borne viral encephalitis (kumlinge disease, kd) and of borrelia burgdorferi (lyme borreliosis, lb). bites of the tick are believed to be common in aland, an island province of finland in the baltic sea. kd has been seen there for many years, and cases of lb have been diagnosed lately. the purpose of this study was to find the incidence of tick-bite among the population with possible implications for the spread of lb. a questio ... | 1990 | 2320965 |
| characterization of finnish borrelia burgdorferi sensu lato isolates by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and with monoclonal antibodies. | thirty-seven borrelia burgdorferi strains, isolated in 1992 from ixodes ricinus in finland, were investigated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page) and by immunoblotting and indirect immunofluorescence assay (ifa) with five to nine monoclonal antibodies (mabs). by sds-page results and reactivities to mabs h3ts, j 8.3, i 17.3, and d6, the 37 isolates were assigned to the species b. burgdorferi sensu stricto (n = 7), borrelia afzelii (n = 17), or borrelia garinii ... | 1995 | 7559935 |
| late lyme borreliosis: epidemiology, diagnosis and clinical features. | lyme borreliosis is endemic in the aland islands. exposure of the inhabitants to bites of the tick ixodes ricinus is heavy. the purpose of this study was to describe symptoms and signs of patients with late lyme borreliosis in this area, and to correlate the findings with the epidemiological setting. the first 100 consecutive patients with late lyme borreliosis found in the region since 1984 are included in this study. neurological, articular and muscular symptoms and signs dominate. general scr ... | 1993 | 8217100 |
| prevalence of tick-borne encephalitis virus in ixodes ricinus ticks in finland. | approximately 20 cases of tick-borne encephalitis (tbe) occur annually in finland. the known endemic areas are situated mainly in the archipelago and coastal regions of finland, with highest incidence in aland islands. ixodes ricinus panels collected in 1996-1997 from two endemic areas were screened for the presence of rna. two distinct rt-pcr methods were applied, and were shown to have an approximate detection limit of 10 focus forming doses (ffd)/100 microl. one out of 20 pools (a total of 13 ... | 2001 | 11285564 |
