Feeding ticks are generally spatially distributed in clusters on vertebrate hosts. To test the
effect of clustering on transmission of a tick-borne pathogen, Borrelia burgdorferi Johnson, …

This study deals with the ecology of Lyme borreliosis in Europe. The relationships between
Borrelia burgdorferi sensu lato spirochetes, Clethrionomys and Apodemus rodent reservoirs …

Borrelia burgdorferi sensu lato (sl), the agent of Lyme disease, is transmitted to the host during
the blood meal of Ixodes ticks. In most unfed ticks, spirochetes are present in the midgut …

The prevalence of ticks infected by Borrelia burgdorferi sensu lato on birds during their
migrations was studied in Switzerland. A total of 1,270 birds captured at two sites were examined …

We studied the relationship between climate and Ixodes ricinus L. tick behavior by following
every day the proportion of ticks questing in a tick population placed in polyamide mesh-…

To evaluate the importance of vertebrate species as tick hosts and as reservoir hosts in two
endemic areas for Lyme borreliosis in Switzerland, we applied molecular methods for the …

Background Throughout Europe, Ixodes ricinus transmits numerous pathogens. Its
widespread distribution is not limited to rural but also includes urbanized areas. To date, …

Background To predict the risk of tick-borne disease, it is critical to understand the ecological
factors that determine the abundance of ticks. In Europe, the sheep tick (Ixodes ricinus) …

Questing Ixodes ricinus L. ticks were collected monthly from 2003 to 2005 on the north- and
south-facing slopes of Chaumont Mountain in Neuchâtel, Switzerland, at altitudes varying …

We compared Ixodes ricinus questing density, the infestation of rodents by immature stages,
and the diversity of Borrelia burgdorferi sensu lato (sl) in questing ticks and ticks collected …
