title: Anaplasma phagocytophilum seroprevalence in equids: a survey in Sicily (Italy).
abstract: This study was undertaken to determine the prevalence of Anaplasma phagocytophilum infection in Equidae and investigate the possibility of exposure to the organism in Sicily (Southern Italy). During the study blood samples were collected in horses and donkeys housed in five of the nine provinces of Sicilian Island. Of 133 horses and 100 donkeys tested, respectively 9.0% and 6.0% were seroactive (IFAT) with A. phagocytophilum antigen. In only 4.7% of the horses, specific A. phagocytophilum DNA was recorded; in donkey, Anaplasma DNA was not found. Our results indicate a low prevalence of A. phagocytophilum in Sicilian equids. This condition does not justify the exclusion of equids from prophylactic plans for this multihost pathogen infection, a zoonosis with a wide distribution in other European countries. However, further studies are necessary to elucidate the possible mechanisms that involve the Equidae as host of this pathogen.
