external and gastrointestinal parasites of the rufous-collared sparrow zonotrichia capensis (passeriformes, emberizidae) in chile.a total of 277 rufous-collared sparrows, zonotrichia capensis müller, 1776 (emberizidae), were examined for external parasites. the birds were captured using mist nets in seven locations in northern and central chile. additionally, seven carcasses from central chile (the biobío region) were necropsied to evaluate the presence of endoparasite infection. ectoparasites were found on 35.8% (99/277) of the examined birds and they were represented by the following arthropods: feather mites amerodectes ...201728977245
new records of ticks (acari: ixodidae) from dogs, cats, humans, and some wild vertebrates in alaska: invasion potential.during 2010-2016, tick specimens were solicited from veterinarians, biologists, and members of the public in alaska. eight species of ticks were recorded from domestic dogs. some ticks were collected from dogs with recent travel histories to other countries or other u.s. states, which appears to explain records of ticks not native to alaska such as amblyomma americanum (l.) (lone star tick), ixodes scapularis (say) (blacklegged tick), and ixodes ricinus (l.). however, we recorded dermacentor var ...201627524823
ticks (acari: ixodidae) on wild birds in north-central argentina.ixodid ticks were collected from wild birds in five ecoregions in north-central argentina, namely: selva de las yungas, esteros del iberá, delta e islas del paraná, selva paranaense and chaco seco. a total of 2199 birds belonging to 139 species, 106 genera, 31 families and 11 orders were captured, but ticks were collected only from 121 birds (prevalence=5.5%) belonging to 39 species (28.1%) and three orders: tinamiformes (tinamidae) and falconiformes (falconidae) in selva de las yungas and passe ...201425108788
vector biodiversity did not associate with tick-borne pathogen prevalence in small mammal communities in northern and central california.vector and host abundance affect infection transmission rates, prevalence, and persistence in communities. biological diversity in hosts and vectors may provide "rescue" hosts which buffer against pathogen extinction and "dilution" hosts which reduce the force of infection in communities. anaplasma phagocytophilum is a tick-transmitted zoonotic pathogen that circulates in small mammal and tick communities characterized by varying levels of biological diversity. we examined the prevalence of a. p ...201424582513
community of arthropod ectoparasites of two species of turdus linnaeus, 1758 (passeriformes: turdidae) in southern rio grande do sul, brazil.this study was aimed at describing the community of arthropod ectoparasites associated with sympatric populations of turdus amaurochalinus and turdus rufiventris and analyzing the aggregation patterns of the chewing lice species, during reproductive and nonreproductive periods, of both turdus species in three areas of the atlantic forest in southern rio grande do sul state (rs), brazil. altogether, we captured 36 specimens of t. amaurochalinus and 53 specimens of t. rufiventris. we identified tw ...201323093206
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
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

the laboratory diagnosis of lyme borreliosis: guidelines from the canadian public health laboratory network.lyme borreliosis is uncommonly seen in canada. most cases have occurred in close proximity to small geographical areas where infected ticks have become established. although few cases are seen, thousands of patients are tested yearly. unless patients are carefully selected and an appropriately sensitive and specific testing algorithm is applied, large numbers of patients without lyme borreliosis will be incorrectly diagnosed. the canadian public health laboratory network has developed the presen ...200718923770

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
geographical distribution patterns and habitat suitability models for presence of host-seeking ixodid ticks in dense woodlands of mendocino county, california.we used drag sampling to examine the geographical distribution patterns of ixodid ticks engaging in open (non-nidicolous) host-seeking behavior in dense woodland habitats of the climatically and ecologically diverse mendocino county in north coastal california. the findings based on this sampling methodology reflect risk of human exposure to host-seeking ticks rather than the true distribution of the ticks. drag sampling in 78 sites yielded 7,860 nymphal or adult ixodes pacificus cooley & kohls, ...200616619628
