Exploration Of Stable Isotope Analysis To Identify Prior Host In Ixodes Scapularis, Imogene Welles

Honors Theses

One of the most enigmatic concepts in tick-borne disease ecology is how to identify the prior host of a questing tick. The ability to do so would provide predictions to directly aid in controlling the spread of the many tick-borne pathogens, including the bacterial spirochete Borrelia burgdorferi, which causes Lyme disease in humans. I explored the application of a novel technique, stable isotope analysis (SIA), to identify the most recent host in molted Ixodes scapularis (black-legged tick). The common reservoir and feeding host, Peromyscus leucopus (white-footed mice; n = 46), were trapped, infested with nymphal ticks, and fed restricted …
