SUMMARYThe occurrence of Anaplasma phagocytophilum was investigated in spleen and serum samples from Swedish moose (Alces alces) in southern Sweden (island and mainland). Samples were analysed for presence of A. phagocytophilum DNA by real-time PCR (n = 263), and for Anaplasma antibodies with ELISA serology (n = 234). All serum samples had antibodies against A. phagocytophilum. The mean DNA-based prevalence was 26·3%, and significant (P < 0·01) temporal, and spatial variation was found. Island moose had significantly (P < 0·001) higher prevalence of A. phagocytophilum DNA than moose from the mainland areas. Two samples were sequenced to determine genetic variation in the 16S rRNA and groESL genes. Genetic sequence similarity with the human granulocytic anaplasmosis agent, equine granulocytic ehrlichiosis agent, and different wildlife-associated A. phagocytophilum variants were observed in the 16S rRNA and groESL genes. Our study shows that moose are exposed to A. phagocytophilum in Sweden, and represent a potential wildlife reservoir of the pathogen.

AbstractThe north-eastern part of Poland is considered an area of high risk for infection with tick-borne diseases, including with human granulocytic ehrlichiosis (HGE) agents. The etiological agent of HGE is Anaplasma phagocytophilum. As the animal reservoir for A. phagocytophilum in the environment serve the species from Cervidae and Bovidae families. European bison (Bison bonasus) and elk (Alces alces) are the big ruminant species, reintroduced to the forests of Middle Europe after many decades of absence. In the foci of zoonotic diseases they are able to play a role as natural reservoir to pathogens, however, their status as protected animals means their study has been rare and fragmentary. The studies of B. bonasus were conducted in Białowieża Primeval Forest and A. alces in Biebrza National Park. PCR amplifications were performed using primers amplifing the end of the groES gene, the intergenic spacer and approximately two-thirds of the groEL gene in the first round, and primers that span a 395-bp region of the groEL gene were used in the second round. The positive results were obtained in B. bonasus and A. alces, the prevalence of infection was 66.7 and 20.0%, respectively. Randomly selected samples were sequenced, sequences were compared with GenBank entries using Blast N2.2.13 and determined as A. phagocytophilum. The results presented herein are the first record of the presence of Anaplasma phagocytophilum in A. alces, and at the same time confirm the previous observations regarding the infection of B. bonasus with A. phagocytophilum.
