ABSTRACT. Though Lyme disease is primarily known as a disease of the northeast, it continues to increase throughout the Midwest. There has been a significant increase in the number of reported cases in recent years in the state of Iowa. In 2015 Dubuque County ranked third in Iowa for Lyme cases, only behind Johnson and Linn counties. To get a better understanding of the prevalence and transmission of B. burgdorferi in eastern Iowa as well as the factors contributing to the prevalence of the disease we trapped forest-based ground-dwelling rodents and performed tick dragging to determine their exposure rates. A pilot study was conducted in 2016 where 84% of captured rodents carried B. burgdorferi. All captures occurred at a single location and included Peromyscus leucopus (white-footed mouse), Peromyscus maniculatus (deer mouse) and Tamias striatus (eastern chipmunk). During 2017, 91 rodents were captured from four different locations and included P. leucopus, P. maniculatus, Microtus pennsylvanicus (meadow vole) and Zapus hudsonius (meadow jumping mouse). Current work is being carried out for 2018 collections includes eight locations. During 2017 and currently in 2018 Ixodes scapularis (blacklegged ticks) were collected and are being tested for the presence of B. burgdorferi via PCR analysis. Each year’s results will be compared to the first year as a basis and analysis will be done to correlate ecological factors influencing the habitat of captured rodents and ticks. We will also be comparing sites based on their geographical distance to the Mississippi River as well as the watersheds that they are in. This project will allow for us to determine the prevalence of the B. burgdorferi in Iowa rodents and ticks, and will also provide information about the role habitat plays in the spread of this infectious disease.
