The prevalence of "Anaplasma phagocytophilum" in host-seeking "Ixodes ricinus" ticks in Norway

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. ricinus ticks collected during a 2-year period from 18 locations situated from northwest to southeast NorwayBiologijos katedraVytauto Didžiojo universiteta
