isolation of lyme disease borrelia from puffins (fratercula arctica) and seabird ticks (ixodes uriae) on the faeroe islands.this is the first report on the isolation of lyme disease borrelia from seabirds on the faeroe islands and the characteristics of its enzootic cycle. the major components of the borrelia cycle include the puffin (fratercula arctica) as the reservoir and ixodes uriae as the vector. the importance of this cycle and its impact on the spread of human lyme borreliosis have not yet been established. borrelia spirochetes isolated from 2 of 102 sampled puffins were compared to the borreliae previously o ...199910074497
variable exposure and immunological response to lyme disease borrelia among north atlantic seabird species.colonial seabirds often breed in large aggregations. these individuals can be exposed to parasitism by the tick ixodes uriae, but little is known about the circulation of pathogens carried by this ectoparasite, including lyme disease borrelia. here we investigated the prevalence of antibodies (ab) against borrelia burgdorferi sensu lato in seabird species sampled at eight locations across the north atlantic. using enzyme-linked immunosorbent assay tests, we found that the prevalence of anti-borr ...200818577503
host-dependent genetic structure of parasite populations: differential dispersal of seabird tick host races.despite the fact that parasite dispersal is likely to be one of the most important processes influencing the dynamics and coevolution of host-parasite interactions, little information is available on the factors that affect it. in most cases, opportunities for parasite dispersal should be closely linked to host biology. here we use microsatellite genetic markers to compare the population structure and dispersal of two host races of the seabird tick ixodes uriae at the scale of the north atlantic ...200312683525
