Dermacentor variabilis, also known as the American dog tick or wood tick, is a species of tick that is known to carry bacteria responsible for several diseases in humans, including Rocky Mountain spotted fever and tularemia (Francisella tularensis). It is one of the best-known hard ticks. Diseases are spread when it sucks blood from the host.
Tick paralysis is believed to be due to toxins found in the tick's saliva that enter the bloodstream while the tick is feeding. The two ticks most commonly associated with North American tick paralysis are the Rocky Mountain wood tick (Dermacentor andersoni) and the American dog tick (Dermacentor variabilis); however, 43 tick species have been implicated in human disease around the world.

As ticks must be attached for at least six hours to transmit Rocky Mountain spotted fever and more than 24 hours to transmit Lyme disease, frequent checks are crucial in avoiding tick-borne illnesses.
Biological vector transmission is through ticks that carry a blood parasite able to cause anaplasmosis. The most common Anaplasmosis-causing tick is Ixodes scapularis, also known as the black-legged tick or the deer tick. [9] [10] Ticks who contain species of many different Anaplasma species can transmit this disease through a bite. The blood ...

The ticks that transmit Lyme disease are hard ticks. [4] Ticks often have a preferred host, but may still attach to a different host when called for. Their preferred host may change depending on the tick's stage of development (eg larval vs adult) and the host may or may not carry the transmittable pathogen. [3]
Ticks, which live by feeding off of the blood of mammals and birds, commonly spread Lyme disease, and also rarer diseases such as Rocky Mountain spotted fever, deer-tick virus, anaplasmosis and ...
