Anaplasmosis
Anaplasmosis is a disease caused by the bacteria Anaplasma phagocytophilum which infects white blood
cells (neutrophils). Anaplasma was previously known as human granulocytic ehrlichiosis (HGE) or human
granulocytic anaplasmosis (HGA). Signs and symptoms of anaplasmosis include: fever, headache, malaise,
and body aches. Encephalitis/ meningitis may occur but is rare. Anaplasmosis is transmitted to a person
through the bite of an infected deer tick (Ixodes scapularis).
Anaplamsa cases appear to be increasing
in Maine as the vector (the deer tick) is found throughout the state. Anaplasma is treatable, and is
best prevented by avoiding exposure to ticks.
