MT-CYB and babesiosis: KCDC-1 and KCDC-GT-270 were highly identical and formed a clade including ovine B. motasi Ningxian in China (JX440507) based on COB and ovine B. motasi Ningxian in China (JX866781) based on COX3. This indicated that the identified Babesia parasites might be B. motasi, and this is the first study to detect B. motasi in human babesiosis and H. longicornis in Korea.
