Anaplasmosis

Black-legged (Deer) Tick

 

Anaplasmosis (formerly called human granulocytic ehrlichiosis) is caused by the bacterium Anaplasma phagocytophilum. It is spread to people through the bite of an infected Black-legged (“deer”) tick (Ixodes scapularis). Treatment is available; however if it is delayed, or there are underlying medical conditions, symptoms can become more severe. The best way to prevent anaplasmosis is to prevent tick bites.
