First case of human babesiosis in Korea: detection and characterization of a novel type of Babesia sp. (KO1) similar to ovine babesia.

چکیده
We report on the first case of human babesiosis in Korea. The intraerythrocytic parasite (KO1) in the patient's blood mainly appeared as paired pyriforms and ring forms; but Maltese cross forms were not seen, and the parasite showed morphological features consistent with those of the genus Babesia sensu stricto. The sequence of the 18S rRNA gene of KO1 was closely related to that of Babesia spp. isolated from sheep in China (similarity, 98%). The present study provides the first evidence of the presence of a hitherto unidentified, new type of Babesia parasite capable of infecting humans.

The activity and efficacy of Iranian synthesized imidocarb dipropionate (imidorazi) has been tested against Babesia ovis infection in experimentally and naturally affected sheep. The results indicated that the drug is effective and could be used for treatment of sheep and goats babesiosis. The effectiveness of imidorazi is also similar to the imizol (imidocarb dipropionate) imported from abroad.
