Ehrlichiosis is a relatively new tick-borne disease; the first human case was identified in 1986. Ehrlichia chaffeensis is an intracellular rickettsia-like bacterium that preferentially infects monocytes and is sequestered in parasitophorous vacuoles referred to as morulae. Ehrlichia bacteria are transmitted to humans by the bite of an infected tick. The lone star tick (Amblyomma americanum) is the primary vector of both Ehrlichia chaffeensis and Ehrlichia ewingii in the United States. Typical symptoms include: fever, headache, fatigue, and muscle aches.

Each of these infectious diseases is designated by the major target cell: human monocytic ehrlichiosis is caused by Ehrlichia chaffeensis, and human granulocytic ehrlichiosis by an E. The onset of symptoms usually occurs about three weeks after an individual has been bitten by a tick carrying the bacterium Ehrlichia chaffeensis. The most common symptoms are: chills fever muscle aches headaches general malaise nausea diarrhea
