The First Report of Serological Detection of Babesia caballi by cELISA in a Horse During Serological Survey of Piroplasmosis in Imported Horses at Shanghai Port, China.

The aim of this study was to determine the seroprevalence of Babesia caballi and Theileria equi in horses imported into Shanghai port. Between 2018 and 2019, 344 horse sera samples were collected and tested for B. caballi and T. equi, using commercially available kits. Only one B. caballi seropositive sample was detected. To the best of our knowledge, this is the first report of a B. caballi seropositive in imported horses at Shanghai port, which reflects the importance of monitoring piroplasmosis seroprevalence in imported horses.
