lyme disease: seroprevalence and vector survey in southern alberta. 19938148785
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
ixodes scapularis ticks collected by passive surveillance in canada: analysis of geographic distribution and infection with lyme borreliosis agent borrelia burgdorferi.passive surveillance for the occurrence of the tick ixodes scapularis say (1821) and their infection with the lyme borreliosis spirochaetes borrelia burgdorferi s.l. has taken place in canada since early 1990. ticks have been submitted from members of the public, veterinarians, and medical practitioners to provincial, federal, and university laboratories for identification, and the data have been collated and b. burgdorferi detected at the national microbiology laboratory. the locations of colle ...200616739422
isolation of borrelia burgdorferi, the lyme disease spirochete, from rabbit ticks, haemaphysalis leporispalustris--alberta. 19957620455
investigation of the population structure of the tick vector of lyme disease ixodes scapularis (acari: ixodidae) in canada using mitochondrial cytochrome c oxidase subunit i gene sequences.genotyping of ixodes scapularis say (acari: ixodidae) ticks could enhance understanding of the occurrence and genotypes of i. scapularis-borne pathogens. we investigated the utility of mitochondrial (mt) cytochrome c oxidase subunit i gene (cox1) sequences as a tool for understanding the population structure of i. scapularis collected in canada, where we also investigated the geographic occurrence of different cox1 haplotypes. sequences obtained from 414 ticks were one of 55 unique haplotypes, m ...201323802450
