Amblyomma is a genus of hard ticks. Some are disease vectors, for example the Rocky Mountain spotted fever in United States or ehrlichiosis in Brazil. This genus is the third largest in the family Ixodidae, with its species primarily occupying the torrid zones of all the continents.

The Gulf Coast tick (Fig. 1), Amblyomma maculatum, was first described by Koch in 1844. Gulf Coast ticks are found in grass prairies and coastal uplands throughout much of the western hemisphere. The ticks are ectoparasites that feed on a variety of birds and mammals, and will readily bite humans.

Members of the genus, Amblyomma, are known vectors of a variety of diseases in humans. In North America, A. americanum transmits Francisella tularensis (tularemia), Ehrlichia chaffensis (ehrlichiosis), and Rickettsia rickettsii (Rocky Mountain spotted fever, or RMSF).

Amblyomma americanum, also known as the lone star tick, the northeastern water tick, or the turkey tick, is a type of tick indigenous to much of the eastern United States and Mexico, that bites painlessly and commonly goes unnoticed, remaining attached to its host for as long as seven days until it is fully engorged with blood.

The lone star tick, Amblyomma americanum, was first described by Linnaeus in 1758. Lone star ticks feed on the blood of various animals (domesticated and wild) as well as humans.

The tick Amblyomma americanum is one of the most frequently identified ticks in the United States with an expanding spectrum of human disease given its vast geographic range.

Amblyomma ticks are large, three-host parasites. They have eyes and long, robust mouthparts. They are more or less brightly ornamented and generally confined to the tropics and subtropics. Adults and immatures of 37 species in this genus parasitize reptiles.

The lone star tick (Amblyomma americanum) transmits Ehrlichia chaffeensis and Ehrlichia ewingii, causing human ehrlichiosis, tularemia, and STARI. The lone star tick is primarily found in the southeastern and eastern United States.

The lone star tick (Amblyomma americanum) is a major vector of several viral, bacterial, and protozoan pathogens affecting humans and other animals in the United States (Childs and Paddock 2003; Goddard and Varela-Stokes 2009).
