01894-A: Documentation of Disease-Causing Ticks in a Field Trial Environment for the Purpose of Developing Practical and Cost-Effective Strategies for Tick Control
Grant Status: Open
Ehrlichia is a type of bacteria that is spread by tick bites and causes serious canine health problems, including chronic inflammatory disease, bleeding problems, and kidney damage. Unfortunately, Ehrlichia incidence is increasing in the southeastern United States and is of emerging concern to hunting and field trial dogs. To address this health concern, Dr. Fryxell will conduct an in-depth Ehrlichia prevalence study. Focusing on the 18,400 acre Ames Plantation in western Tennessee (site of the National Field Trial Championship for All-age bird dogs), she will complete three main objectives: 1) Collect ticks from different habitats and dogs visiting the Ames Plantation for field trial events, 2) Screen all collected ticks for Ehrlichia prevalence and document the Ehrlichia species present, and 3) Correlate Ehrlichia presence and absence with environmental data (e.g., climate, land use land cover, and soils data) to identify variables associated with pathogen presence and absence. Knowledge of the preferred habitat and environmental variables for Ehrlichia is essential for the implementation of current vector control strategies and for the development of novel management strategies that improve the efficacy of currently available vector control methods.

Help Future Generations of Dogs
Participate in canine health research by providing samples or by enrolling in a clinical trial. Samples are needed from healthy dogs and dogs affected by specific diseases.
