It usually feeds on deer and mice
Ixodes scapularis
It is a blacklegged tick
Lymes disease is contracted in humans in only one way. The western blacklegged tick in British Columbia or the blacklegged tick, sometimes called the deer tick, carry bacteria which is spread to humans, causing Lymes disease. Ticks become infected by feeding on infected animals. http://www.accuconference.com/
Granulocytic ehrlichiosis is probably spread by the blacklegged tick Ixodes scapularis
Blacklegged ticks are carriers of lyme disease
In the United States, Borrelia burgdorferi is primarily carried by the black-legged tick, also known as the deer tick. These ticks become infected with the bacteria by feeding on animals such as mice and deer that harbor the pathogen. When the infected ticks then feed on humans, they can transmit the bacteria, leading to Lyme disease.
deer You don't specify the infection, so I will use Lyme Disease as an example. The nymph/baby tick goes for a small host. Prior to feeding, the nymph tick is not infected with anything. If the nymph deer tick feeds on a deer mouse, which are the carriers of Lyme disease, they become infected. If the nymph tick feeds on an animal, like a lizard, that isn't infected, the tick won't be infected. The progression is usually, deer mouse then larger host, such as deer, human, dog or other larger mammal.

it is a deer tick
The deer tick (Ixodes scapularis) is an intermediate host for Borrelia burgdorferi, the bacterium that causes Lyme disease. The bacterium is transmitted to humans through the bite of an infected deer tick.
