| lyme disease and migrating birds in the saint croix river valley. | during a study of migrating land birds in 1987, we examined over 9,200 individual birds representing 99 species from the saint croix river valley, a lyme disease-endemic area of east central minnesota and northwestern wisconsin. we found that 250 deer tick (ixodes dammini) larvae and nymphs infested 58 birds from 15 migrant species; 56 ticks (22.4%) were positive for the lyme disease spirochete borrelia burgdorferi. five ground-foraging migrant bird species favoring mesic habitats, veery (cathar ... | 1989 | 2782872 |
| prevalence of the lyme disease spirochete, borrelia burgdorferi, in deer ticks (ixodes dammini) collected from white-tailed deer (odocoileus virginianus) in saint croix state park, minnesota. | during a special two-day hunt (11, 12 november 1989) in saint croix state park, minnesota (usa), one side of the neck for each of 146 white-tailed deer (odocoileus virginianus) was examined for ticks. of the 5,442 ticks collected, 90% (4,893) were the winter tick, dermacentor albipictus, and 10% (549) were the deer tick, ixodes dammini, the primary vector of the causative agent of lyme disease, borrelia burgdorferi. adult males had the greatest frequency of infestation of either d. albipictus (1 ... | 1993 | 8445791 |
| complete sequence characterization of the genome of the st croix river virus, a new orbivirus isolated from cells of ixodes scapularis. | an orbivirus identified as st croix river virus (scrv) was isolated from cells of ixodes scapularis ticks. electron microscopy showed particles with typical orbivirus morphology. the scrv genome was sequenced completely and compared to previously characterized orbivirus genomes. significant identity scores (21-38%) were detected between proteins encoded by segments s1, s2, s4, s5, s6, s8, s9 and s10 of scrv and those encoded by segments s1, s3, s4, s5, s6, s7, s9 and s10, respectively, of blueto ... | 2001 | 11257184 |
