Prepared microscope slide: Arthropoda: Dermacentor andersoni nymph, 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.
