Human Granulocytic Anaplasmosis Acquired in Scotland, 2013

摘要

To the Editor: Human granulocytic anaplasmosis is a tick-borne disease caused by Anaplasma phagocytophilum, an obligate intracellular gram-negative bacterium that infects granulocytes. The usual clinical signs and symptoms include nonspecific fever, chills, headache, and myalgia. Infection is usually mild or asymptomatic, but severe systemic complications can occur, leading to a need for intensive care and estimated fatality rates of 0.5%–1.0% (1,2).
