Title: The prevalence of Anaplasma phagocytophilum in host-seeking Ixodes ricinus ticks in Norway
Abstract: In recent years, cases of human granulocytic anaplasmosis (HGA), as well as presence of A. phagocytophilum in ticks and various vertebrate hosts, have been reported throughout Europe. In Norway, tick-borne fever caused by A. phagocytophilum has been recorded in moose, red deer, roe deer and sheep [1], as well as in humans [2]. The prevalence of A. phagocytophilum in I. ricinus ticks is important for risk assessment of HGA. In this study, we present the prevalence of A. phagocytophilum in host-seeking I.
