Question 51

To determine the literal meaning of "Xero/derma", we analyze the word parts. "Xero" comes from the Greek word for "dry", and "derma" means "skin". So we match this with the option that has "dry/skin".

Rocky Mountain Spotted Fever is caused by Rickettsia rickettsii, which is transmitted to humans by the bite of an infected tick (specifically, ticks like the American dog tick, Rocky Mountain wood tick, etc.). Worms, mosquitoes, and birds are not the vectors for this rickettsia.
