Caption: As one of the primary natural hosts to the Rocky Mountain wood tick, Dermacentor andersoni (see PHIL 10865), this Columbian ground squirrel, Urocitellus columbianus, was infested by numerous nymphal staged, D. andersoni ticks. You can see these ticks obtaining their blood meal from this host, as they nestled around the animal’s right eye and ear. D. andersoni is the vector responsible for transmitting the Coltivirus, Colorado tick fever (CTF) to humans.
