What causes ehrlichiosis?

Ehrlichiosis is caused by different species of ehrlichia bacteria. The Lone Star tick found in south-central, southeastern and eastern coastal states is the primary carrier of bacteria causing ehrlichiosis. Black-legged ticks, commonly called deer ticks, in the Upper Midwest are less common carriers.

Is Ehrlichia the same as ehrlichiosis?

Ehrlichiosis and anaplasmosis are caused by rickettsial-like bacteria. Ehrlichiosis is caused mainly by Ehrlichia chaffeensis; anaplasmosis is caused by Anaplasma phagocytophilum. Both are transmitted to humans by ticks.
