What's Happening?
University of Kentucky (UK) research students, advised by Hannah Tiffin, Ph.D., assistant Extension professor of veterinary entomology, are conducting a study to gather baseline data on tick species, their host animals, and the impact of various land
use types in Kentucky. The project, primarily funded by the UK Student Sustainability Council, focuses on the role of wild mice in tick life cycles. Mice are considered 'tick magnets' due to their abundance and ability to move ticks from wilder areas to human and livestock-interacting environments. They also harbor various pathogens, including Borrelia burgdorferi, which causes Lyme disease. The research team employs multiple sampling methods, including tick dragging, trapping and checking wild mice, and utilizing artificial mouse nesting sites. Collected ticks are identified and sent to a lab to determine the presence of disease-causing pathogens.
Why It's Important?
This research is crucial for filling an information gap in Kentucky regarding tick ecology and the transmission of tickborne diseases. Understanding how wild mice contribute to tick dispersal and pathogen circulation is vital for developing effective public health strategies. As ticks can transmit a range of diseases to humans and animals, including Lyme disease, the study's findings will help inform targeted prevention and control measures. The project also serves as a valuable educational opportunity, training undergraduate and graduate students in wildlife handling, tick removal, and tissue collection, thereby building expertise in vector-borne disease research. The potential development of community-based science initiatives using novel surveillance tools like mouse nesting boxes could significantly expand tick monitoring efforts.
What's Next?
The UK research team will continue to collect and analyze data on tick species and pathogens across different land-use types in Woodford County. Graduate research assistant Ashley Russo is assessing alternative mouse capture methods, such as nesting boxes, to reduce field time and mouse handling, with the hope of expanding this into a community science initiative. The collected ticks will be sent to Virginia Commonwealth University for pathogen identification. The findings from this study are expected to provide a clearer picture of tick distribution and seasonality in Kentucky, which will be used to develop more effective and localized tick prevention recommendations for residents, farmers, and public health officials. Future efforts may involve validating candidate genes associated with parthenogenesis in ticks.
Beyond the Headlines
The study's focus on wild mice as 'tick magnets' highlights a less obvious but critical aspect of tickborne disease ecology. While public attention often centers on larger hosts like deer, the role of small mammals in maintaining pathogen reservoirs and facilitating tick spread is equally significant. The exploration of alternative, less labor-intensive surveillance methods, such as mouse nesting boxes, could revolutionize tick monitoring, making it more accessible for researchers and potentially for community science programs. This approach could foster greater public engagement in understanding and mitigating tick risks. Furthermore, the interdisciplinary nature of the research, combining veterinary entomology, wildlife management, and public health, exemplifies the collaborative effort required to address complex ecological and health challenges.
