| intrinsic competence of three ixodid ticks (acari) as vectors of the lyme disease spirochete. | we compared the intrinsic vector competence of ixodes dammini spielman et al., dermacentor variabilis (say), and amblyomma americanum (l.) for the lyme disease spirochete (borrelia burgdorferi johnson et al.) on prudence island, rhode island, a lyme disease-endemic site where all three ticks occur together. natural and experimental spirochete infection rates were determined in those ticks and their degree of contact with white-footed mice (peromyscus leucopus), the principal reservoir host, was ... | 1990 | 2388239 |
| serologic analyses of peromyscus leucopus, a rodent reservoir for borrelia burgdorferi, in northeastern united states. | an enzyme-linked immunosorbent assay (elisa) and indirect fluorescent-antibody test were used to detect antibodies to borrelia burgdorferi, the causative agent of lyme disease, in peromyscus leucopus (white-footed mouse). of the 661 mice captured in connecticut, rhode island, and new york during 1980 and 1983 to 1987, 166 (25.1%) had antibodies to b. burgdorferi by elisa. comparative analyses of 210 serum specimens, collected in areas where lyme disease is endemic, revealed a threefold differenc ... | 1988 | 3384925 |
| histopathology of peromyscus leucopus naturally infected with pathogenic ny-1 hantaviruses: pathologic markers of hps viral infection in mice. | hantavirus research is impeded by the absence of animal models of viral pathogenesis. we have studied the histopathology of mice (p. leucopus) naturally infected with the ny-1 hantavirus on shelter island, new york. five mice were determined to be seropositive in western blotting to four corners virus nucleocapsid protein and had serum antibodies to seoul and puumala hantavirus antigens by immunofluorescence assay. hantavirus gene segments of the ny-1 hantavirus were identified in these mice and ... | 1996 | 8600313 |
| spatial distribution of larval ixodes scapularis (acari:ixodidae) on peromyscus leucopus and microtus pennsylvanicus at two island sites. | larval blacklegged ticks, ixodes scapularis, were collected from white-footed mice. peromyscus leucopus, on prudence island (where microtus pennsylvanicus were not captured) and from meadow voles. m. pennsylvanicus, on patience island (where p. leucopus was absent) in narragansett bay, rhode island from june to october 1992. ixodes scapularis larvae were also collected by flagging in the vicinity of host captures. on both islands, the relative density of larvae changed from july to september in ... | 1997 | 9105297 |
| reservoir competence of the meadow vole (rodentia: cricetidae) for the lyme disease spirochete borrelia burgdorferi. | the reservoir competence of the meadow vole, microtus pennsylvanicus ord, for the lyme disease spirochete borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner was established on patience island, ri. meadow voles were collected from 5 locations throughout rhode island. at 4 of the field sites, m. pennsylvanicus represented only 4.0% (n = 141) of the animals captured. however, on patience island, m. pennsylvanicus was the sole small mammal collected (n = 48). of the larval ixodes scap ... | 1998 | 9775612 |
| enzootic transmission of deer tick virus in new england and wisconsin sites. | to determine whether rodents that are intensely exposed to the deer tick-transmitted agents of lyme disease, human granulocytic ehrlichiosis, and human babesiosis are also exposed to deer tick virus (dtv), we assayed serum samples from white-footed mice (peromyscus leucopus) and meadow voles (microtus pennsylvanicus) in sites densely infested by deer ticks. to conduct serosurveys, we developed an enzyme-linked immunosorbent assay (elisa) and western blot assay by cloning, expressing, and purifyi ... | 2000 | 11357992 |
