Which disease is NOT transmitted by American Ticks?

Bubonic Plague is the correct answer because it is primarily transmitted by fleas that infest rodents, not by ticks. The bacteria responsible for Bubonic Plague, Yersinia pestis, is typically spread through flea bites or contact with infected animals. In contrast, Rocky Mountain spotted fever, Lyme disease, and Tularemia are all illnesses that are transmitted by American ticks.

Rocky Mountain spotted fever is linked specifically to the bite of the American dog tick and other tick species. Lyme disease is caused by the bacterium Borrelia burgdorferi and is primarily transmitted through the bite of black-legged ticks. Tularemia can be transmitted by several vectors, including ticks, particularly the dog tick and deer tick.

Thus, the distinguishing factor for Bubonic Plague is its method of transmission through fleas, which sets it apart from the diseases that American ticks carry.
