Anaplasmosis is a rickettsial zoonosis mediated by blood-sucking arthropods, such as ticks, flies, andmosquitos. Migratory birds are common hosts of ticks that are mediators of anaplasmosis, in particular, the tick infectionrate in thrushes (family Turdidae) has been known to be high. The main purpose of this study is to survey the occurrenceand prevalence of Anaplasma spp. from the migratory thrushes in Jeju island. We collected blood samples from 6thrushes rescued at the Jeju Wildlife Rescue Center and from 34 wild-caught thrushes on Mara island which is asatellite island of Jeju. As a result, the nested PCR confirmed that seven out of 40 individuals (17.5%) were infectedby Anaplasma spp. and all of them were identified as A. phagocytophilum based on sequences obtained from partial16S rRNA. All the infected birds were on their northward migration in spring, our results suggest that the Turdidaefamily, which is a common and abundant migrant group passing through Jeju island, may act a role as active reservoirand disperser of A. phagocytophilum causing potential influx of the zoonotic pathogens from its wintering groundsin lower latitude to the mainland Korea as well as Jeju.
