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
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.
