Amblyomma maculatum Koch 1944 - (Gulf Coast tick)
This tick is found in North- and South America. Originally, its distribution was mainly confined to the Gulf Coast states and to the south-eastern parts of the U.S. Starting in the 2nd half of the 20th century, it has considerably expanded its range and it can be now found in most eastern and southern parts of the U.S., as well as in various other countries of Central and South America.
The hosts of A. maculatum are predominately small wild and domestic mammals. However, it may also bite humans and is a vector Rickettsia parkeri causing eschar-associated spotted fever group rickettsiosis in humans. In some populations up to 50% of the ticks can carry R. parkeri. It can further transmit other Rickettsia species and Hepatozoon americanum, the agent responsible for American canine hepatozoonosis.
