Prepared microscope slide: Arthropoda: Dermacentor andersoni male adult, commonly known as the Rocky Mountain wood tick.
D. andersoni is a tick that is common in the Western United States where it is a parasite feeding on the blood of many mammals in the wild. They also infest domestic animals, particularly dogs. This tick is a vector of many different kinds of diseases. Potential bacterial infections include Rocky Mountain spotted fever, Ehrlichiosis (both Human granulocytic and Human monocytic),and Boutonneuse fever among those caused by rickettsiales; Lyme disease and Relapsing fever from spirochaetes; Tularemia from thiotrichales. Viral infections include Colorado tick fever, Crimean-Congo hemorrhagic fever, Heartland virus, Kyasanur forest disease, Powassan encephalitis, Omsk hemorrhagic fever, and Tick-borne encephalitis.. It is also a vector for the protozoan infection Babesiosis. Through the injection of a neurotoxin it can also cause Tick paralysis.

This slide was prepared by Ward’s Natural Science Establishment. From the quality of the work, and the general appearance, it is estimated to have been prepared prior to 1950.
This slide is placed here primarily so that everyone with an interest would be able to view it as though viewing through a microscope.
