Deer Tick (Ixodes dammini)

The deer tick (Ixodes dammini) is responsible for the transmission of Lyme disease and is about the size of a sesame seed. Rheinberg illumination was used to image the body of a nymph-stage deer tick. Deer ticks are found in grassy areas and in woodlands where they exist in three life stages of larva, nymph, and adult. These ticks infest warm blooded animals including man, dogs, cats, horses, cows, and (of course) white-tailed deer. Several species of Ixodes carry the Lyme disease bacteria, which has become the most frequently diagnosed tick-borne illness in the United States. The two lower images (both at 60x magnification) were made from two individual specimens.

Rheinberg illumination digital images were recorded using a reflected light configuration consisting of auxiliary fiber optics light tubes covered with colored gels (oblique specimen illumination). Another, much darker gel was placed over the frosted diffusion screen to serve as the background color.
