Abstract

Siberian Roe deer which inhabits Jeju Island is unique native species. Most of all the roe deer infect a lot of ticks, which can affect its population directly and can act as a vector to spread vector-borne diseases. The purposes of this study were to identify the ticks and detect the piroplamsosis on the roe deer in Jeju island. We collected ticks and blood samples in 23 roe deer rescued and treated at the Jeju Wildlife Rescue Center. As a result, we identified the one species of ticks, Haemaphysalis longicornis in roe deer and detected the closely related to Theileria luwenshuni in all blood samples (100%) and 8 pooled ticks (34.8%). These results indicate that there may be a high prevalence particularly of T. luwenshuni infection in Jeju wild roe deer and H. longicornis is a major vector of these diseases. It suggested that Jeju roe deer may act as reservoirs for these zoonotic pathogens.

제주도에 서식하는 노루는 육지부 다른 종으로 대부분이 진드기에 심하게 감염되어 있다. 제주노루가 진드기 매개질병에 감염 및 다른 야생동물이나 가축에게 질병을 전파할 수 있다. 이에 본 연구에서는 제주야생동물구조센에서 구조 및 치료되는 제주노루 23마리의 혈액과 진드기를 대상으로 진드기 종을 동정하고 주혈원충 감염을 확인하였다. 구조된 노루의 대부분은 심하게 진드기에 감염되었고 모두가 작은소참진드기(100%)였다. 감염노루 혈액과 진드기를 대상으로 주혈원충에 대한 PCR, RFLP 및 염기서열 분석한 결과 혈액시료 모두(100%)에서 Theileria luwenshuni로 확인되었으며, 진드기에서는 23개군중 8개군(34.8%)에서 확인되었다. 제주 노루 감염 진드기는 주로 작은소참진드기며, 이들이 T. luwenshuni 매개함을 확인하였다. 그러나 감염에 따른 혈액 및 혈청학적 검사에서 정상소견과 유의적 차이를 보이지 않았다. 앞으로 사람이나 가축으로 질병을 전파할 수 있는 진드기 매개질병 보균숙주로서 가능성이 있음으로 지속적인 조사 관찰이 필요하다.
