Anaplasmosis is a disease caused by a rickettsial parasite of ruminants (large hoofed herbivores). It can be contracted from tick bites. The most common tick that carries the bacterium is Ixodes scapularis, also known as the black-legged tick or the deer tick.

Classic signs and symptoms of anaplasmosis include fever, a decreased number of white blood cells, platelets in the bloodstream, and abnormally elevated levels of liver enzymes. A rash may appear at the site of the tick bite, as it is sometimes co-transmitted with Lyme disease.
