제주 노루의 흡혈절지동물 매개에 의한 주혈기생충성 질병 조사

Abstract

Siberian Roe deer which inhabits Jeju Island is unique native species, because Jeju roe deer has significant differences in morphology compared with Inland roe deer in Korea because of geographical isolation. Most of all the wild deer infect a lot of blood sucking arthropods, which can affect its population directly and can act as a vector to spread vector-borne diseases. These diseases have not been evaluated in roe deer in Korea. The purposes of this study were to identify blood sucking arthropods on roe deer, and examine the prevalence of vector-borne diseases including piroplasmosis (Babesia/Thelieria spp.) and Anaplasmosis (Anaplasma/Ehrlicha spp.) in wild and captive Jeju roe deer and in the blood suckling arthropods. We identified blood-sucking arthropods from roe deer and examined the vector-borne diseases in 31 roe deer (23 wild deer from Jeju Wildlife Rescue Center, 8 captive deer from Roe Deer Observation Center) and the arthropods (ticks, keds). As a result, two kinds of blood sucking arthropods on roe deer were collected; one species of tick (Haemaphysalis longicornis) and one species of ked (Lipoptena fortisetosa). Thelieria luwenshuni was detected in 4 captive deer (50.0%), 23 wild deer (100%), and 8 H. longicornis (34.8%), but Babesia crassa was detected from only 1 captive roe deer (12.5%). A. phagocytophilum was detected in 2 captive (25.0%), 9 wild deer (39.1%), and 4 H. longicornis (17.4%). Nothing was detected in L. fortisetosa in this study. These results indicate that there may be a high prevalence particularly of Theileria sp. infection in Jeju wild roe deer and H. longicornis is a major vector of these diseases. Also, it suggested that Jeju roe deer may act as reservoirs for these zoonotic pathogens.
