Research title: Quantifying host species contributions to tick and Lyme disease emergence in the Western Isles

Research Summary

Research Summary


The role of deer, livestock and non-native hosts in tick-borne disease emergence in the Western Isles. In the past decade it was reported that the Uist islands (North Uist and South Uist – two islands forming part of the Outer Hebrides) have high levels of tick numbers and cases of Lyme disease. The different islands offer naturally varying reservoir and reproductive host communities, facilitating hypothesis testing of how host communities affect tick populations and pathogen transmission.

Main aims:

1) To determine how the spatial distribution and abundance of deer and livestock relates to the density of questing ticks and Lyme disease risk.

2) To identify the Lyme bacteria reservoir species in order to discern how the introductions of certain mammals to these islands has shifted the pattern of pathogen transmission and maintenance.
