Ixodes dammini is a species of hard-bodied tick that is commonly known as the black-legged tick or deer tick. It is a bloodsucking parasite that transmits a number of serious diseases to humans, including Lyme disease, babesiosis, and anaplasmosis. In addition to its scientific name, the black-legged tick is sometimes referred to as the northern deer tick, Lyme tick, or simply as Ixodes tick. While the name may differ, the dangers posed by the black-legged tick remain the same. Its presence in wooded areas, fields, and grassy areas across the northeastern United States has made it a serious health concern for both humans and animals.
