Human Granulocytic Anaplasmosis: First Reported Case in Canada

Abstract

Human granulocytic anaplasmosis (HGA) is a tick-borne rickettsial infection of peripheral blood neutrophils caused by Anaplasma phagocytophilum. While this infection is increasingly recognized as endemic throughout much of the United States, no Canadian cases have been previously described, despite the agent being identified in Canadian ticks. Herein we present a case of HGA acquired in an urban Alberta centre. Canadian physicians must be aware of the possibility of tick-borne rickettsial diseases as etiology of fever in individuals presenting with leukopenia/lymphopenia, thrombocytopenia and elevated transaminases during periods of tick activity. Prompt recognition and treatment are important in minimizing resultant morbidity and mortality.
