avian and mammalian hosts for spirochete-infected ticks and insects in a lyme disease focus in connecticut.spirochetes and their vectors and reservoirs were studied in a lyme disease focus in east haddam, connecticut, from mid-may through september 1983. ixodes dammini subadults were comparable in number on white-footed mice (peromyscus leucopus) (means = 2.9 +/- 3.6 sd) to those on 27 different species of birds (means = 2.3 +/- 4.2 sd) representing 11 families within the order passeriformes. less commonly found ticks on birds (means less than or equal to 0.1) were immature ixodes dentatus and haemap ...19846516460
ticks (acari: ixodidae) infesting wild birds (aves) and white-footed mice in lyme, ct.birds were captured and recaptured (20.8% of 5,297) with japanese mist nets, and white-footed mice, peromyscus leucopus (rafinesque), were caught and recaught (69.1% of 355) with sherman box traps during the late spring, summer, and early fall from july 1989 through october 1991 to study tick-host relationships in lyme, ct. ixodes scapularis say, a vector of lyme disease spirochetes, borrelia burgdorferi sensu stricto johnson, schmid, hye, steigerwalt & brenner, infested 803 birds (15.2%) in 36 ...19957650706
relative importance of bird species as hosts for immature ixodes dammini (acari: ixodidae) in a suburban residential landscape of southern new york state.abundance of birds and their tick parasites were estimated in a residential community located in westchester county, ny, where lyme disease is endemic. in total, 36 bird species (416 captures) were collected, of which 25 species (69%) were parasitized by ticks. ixodes dammini spielman, clifford, piesman & corwin composed 96.4% of the 1,067 ticks found on birds. the bird species most heavily parasitized was house wren, troglodytes aedon vieillot (11.1 ixodes dammini per bird). relative density es ...19938360897
competence of american robins as reservoir hosts for lyme disease spirochetes.to explore the competence of american robins as a reservoir for lyme disease spirochetes, we determined the susceptibility of these birds to tickborne spirochetes and their subsequent infectivity for larval vector ticks. robins acquired infection and became infectious to almost all xenodiagnostic ticks soon after exposure to infected nymphal ticks. although infectivity waned after 2 months, the robins remained susceptible to reinfection, became infectious again, and permitted repeated feeding by ...200010756146
birds and their ticks in northwestern california: minimal contribution to borrelia burgdorferi enzootiology.birds and their attendant ticks were surveyed for infection with the lyme disease spirochete borrelia burgdorferi, in chaparral and woodland-grass habitats in northwestern california from march to july, 1998 to 1999. in total, 234 birds were captured and recaptured (15%); nearly 2.5 times more birds were captured in chaparral than in woodland-grass. overall, 34 species representing 15 families were collected during this study; of these, 24 species were caught in chaparral, 19 in woodland-grass, ...200111534638
reservoir competence of native north american birds for the lyme disease spirochete, borrelia burgdorfieri.reservoir competence for the lyme disease spirochete, borrelia burgdorferi, was tested for six species of native north american birds: american robin, gray catbird, brown thrasher, eastern towhee, song sparrow, and northern cardinal. wild birds collected by mist netting on fire island, ny, were held in a field laboratory in cages over water and locally collected larval ticks were placed on the birds, harvested from the water after engorgement, and tested for infection by direct fluorescentantibo ...200515962798
migratory songbirds disperse ticks across canada, and first isolation of the lyme disease spirochete, borrelia burgdorferi, from the avian tick, ixodes auritulus.during a 3-yr comprehensive study, 196 ixodid ticks (9 species) were collected from 89 passerine birds (32 species) from 25 localities across canada to determine the distribution of avian-associated tick species and endogenous lyme disease spirochetes, borrelia burgdorferi johnson, schmid, hyde, steigerwalt, and brenner. we report the following first records of tick parasitism on avian hosts: the rabbit-associated tick, ixodes dentatus marx, from manitoba and ontario; the mouse tick, ixodes muri ...200517089744
detection of lyme disease spirochete, borrelia burgdorferi sensu lato, including three novel genotypes in ticks (acari: ixodidae) collected from songbirds (passeriformes) across canada.lyme disease is reported across canada, but pinpointing the source of infection has been problematic. in this three-year, bird-tick-pathogen study (2004-2006), 366 ticks representing 12 species were collected from 151 songbirds (31 passerine species/subspecies) at 16 locations canada-wide. of the 167 ticks/pools tested, 19 (11.4%) were infected with borrelia burgdorferi sensu lato (s.l.). sequencing of the rrf-rrl intergenic spacer gene revealed four borrelia genotypes: b. burgdorferi sensu stri ...201020618658
new records of ixodes affinis (acari: ixodidae) parasitizing avian hosts in southeastern virginia.ixodes affinis neumann (acari: ixodidae) is a hard-bodied tick species distributed throughout much of the southeastern united states. although i. affinis does not parasitize humans, it is a competent vector of borrelia burgdorferi sensu stricto, the causative-agent of lyme disease, and thus contributes to the enzootic maintenance of this pathogen. this study presents evidence of i. affinis parasitizing five new host passerine species. during 2012-2014, 1,888 birds were captured and examined for ...201626586535
