Modulatory Effect of Cattle on Risk for Lyme Disease
نویسندگان
چکیده
To determine the effect of cattle on the risk for Lyme disease, we compared the prevalence of spirochete infection in questing vector ticks collected from a pasture with low-intensity cattle grazing with the prevalence in those collected from a site on which no cattle grazed. The presence of cattle limited the prevalence of Borrelia burgdorferi s.l., but not B. miyamotoi, in vector ticks. The reintroduction of traditional, nonintensive agriculture in central Europe may help reduce risk for Lyme disease.

Identification of Two Epitopes on the Outer Surface Protein A of the Lyme Disease Spirochete Borrelia burgdorferi
A murine IgM monoclonal antibody (MA-2C6) with κ-light chains directed against an antigenic determinant of outer surface protein A (OspA) of the Lyme disease spirochete, Borreliaburgdorferi, is produced. This antibody could bind specifically to OspA antigen of several isolates of B. burgdorferi, but not to the non-Lyme disease bacteria such as T. pallidum and B. hermsii. Antibody MA-2C6 was pur...

متن کاملVariations in Ixodes ricinus density and Borrelia infections associated with cattle introduced into a woodland in The Netherlands.
The effect of introduced large herbivores on the abundance of Ixodes ricinus ticks and their Borrelia infections was studied in a natural woodland in The Netherlands. Oak and pine plots, either ungrazed or grazed by cattle, were selected. Ticks were collected weekly by blanket dragging. Borrelia infections were determined by PCR and restriction fragment length polymorphism. Rodent densities wer...

BACKGROUND Lyme disease is caused by Borrelia burgdorferi which is transmitted in Europe by the tick ixodes ricinus. Erythema migrans is a skin lesion which is pathognomonic of Lyme disease. A retrospective study was carried out to determine the geographical distribution of the occurrence of tick bites and erythema migrans in the Netherlands and to identify ecological risk factors. METHODS In...
