birds disperse ixodid (acari: ixodidae) and borrelia burgdorferi-infected ticks in canada.a total of 152 ixodid ticks (acari: ixodidae) consisting of nine species was collected from 82 passerine birds (33 species) in 14 locations in canada from 1996 to 2000. the lyme disease spirochete borrelia burgdorferi johnson, schmidt, hyde, steigerwaldt & brenner was cultured from the nymph of a blacklegged tick, ixodes scapularis say, that had been removed from a common yellowthroat, geothlypis trichas l., from bon portage island, nova scotia. as a result of bird movement, a nymphal i. scapula ...200111476328
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
Widespread dispersal of Borrelia burgdorferi-infected ticks collected from songbirds across Canada.Abstract Millions of Lyme disease vector ticks are dispersed annually by songbirds across Canada, but often overlooked as the source of infection. For clarity on vector distribution, we sampled 481 ticks (12 species and 3 undetermined ticks) from 211 songbirds (42 species/subspecies) nationwide. Using PCR, 52 (29.5%) of 176 Ixodes ticks tested were positive for the Lyme disease spirochete, Borrelia burgdorferi s.l. Immature blacklegged ticks, Ixodes scapularis, collected from infested songbird ...201121864130
different ecological niches for ticks of public health significance in canada.tick-borne diseases are a growing public health concern as their incidence and range have increased in recent decades. lyme disease is an emerging infectious disease in canada due to northward expansion of the geographic range of ixodes scapularis, the principal tick vector for the lyme disease agent borrelia burgdorferi, into central and eastern canada. in this study the geographical distributions of ixodid ticks, including i. scapularis, and environmental factors associated with their occurren ...201526131550
lyme disease risk in dogs in new brunswick.this study assessed the seroprevalence of anti-borrelia burgdorferi antibodies in new brunswick dogs. testing of 699 serum samples from dogs across the province revealed a 6% province-wide seropositivity, more than 6 times higher than that found in 2008. the rapid increase in seropositivity indicates increased lyme disease risk to both canine and human health.201627587892
bell palsy in lyme disease-endemic regions of canada: a cautionary case of occult bilateral peripheral facial nerve palsy due to lyme disease.lyme disease caused by the spirochete borrelia burgdorferi is a multisystem disorder characterized by three clinical stages: dermatologic, neurologic, and rheumatologic. the number of known lyme disease-endemic areas in canada is increasing as the range of the vector ixodes scapularis expands into the eastern and central provinces. southern ontario, nova scotia, southern manitoba, new brunswick, and southern quebec are now considered lyme disease-endemic regions in canada. the use of field surve ...201222967702
