| first isolations of borrelia burgdorferi from rodents collected in northern europe. | spirochetes were found in 13% of ixodes ricinus collected from an island, near stockholm where human borreliosis is endemic. borrelia burgdorferi was cultivated from the kidney and/or spleen of wild rodents (clethrionomys glareolus and apodemus flavicollis) from the same island. spirochetes were identified as borrelia burgdorferi by indirect immunofluorescence assays using species and genus specific monoclonal antibodies. in these tests the spirochetes could not be differentiated from strains pr ... | 1988 | 3190915 |
| tick-borne borrelia infection in sweden. | spirochetes were cultivated from 17% of 114 ixodes ricinus ticks in the stockholm area. three strains of these spirochetes were selected for studies by electron microscopy. these three strains had definite morphological similarities to spirochetes of the genus borrelia, as judged by the number of flagella, absence of cytoplasmic tubules, and dimensions. the three strains were not identical, but seemed to consist of two different kinds of cells, one with eight and one with eleven flagella. the th ... | 1985 | 3903977 |
| transmission of borrelia burgdorferi s.l. from mammal reservoirs to the primary vector of lyme borreliosis, ixodes ricinus (acari: ixodidae), in sweden. | factors regulating prevalence of borrelia burgdorferi s.l. johnson, schmid, hyde, steigerwalt & brenner in ixodes ricinus (l.) were examined during 1991-1992 at bogesund, near stockholm in south-central sweden. nine species of small and medium-sized mammals (sorex araneus l., s. minutus l., neomys fodiens pennant, clethrionomys glareolus [schreber], microtus agrestis [l.], apodemus sylvaticus [l.], a. flavicollis [melchior], lepus europaeus pallas, l. timidus l.) were found to infect feeding tic ... | 1994 | 7815401 |
| epidemiological studies of lyme borreliosis and tick-borne encephalitis. | the hard tick ixodes ricinus, vector of borrelia burgdorferi and tbe virus (tbev), is most abundant in the southern and central parts of sweden. about 2000 cases of lyme borreliosis (lb) and 50-80 cases of tick-borne encephalitis (tbe) are estimated to occur in sweden annually. five populations, including 903 individuals living in five different areas close to stockholm where lb and tbe are endemic, were studied with regard to the clinical manifestations and antibody prevalence of lb and tbe. th ... | 1994 | 8047853 |
| seasonal variation in the capacity of the bank vole to infect larval ticks (acari: ixodidae) with the lyme disease spirochete, borrelia burgdorferi. | seasonal variation in the capacity of bank voles, clethrionomys glareolus (schreber), to infect larval ixodes ricinus (l.) ticks with borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner was examined from may through october 1991 at bogesund, near stockholm in south-central sweden. although larval infestations of bank voles were greatest in june and july, nearly 70% of all larval ticks infected with spirochetes by bank voles at this site became infected during august and september. ... | 1993 | 8360909 |
