초록

Orientia tsutsugamushi 에 의해 발생하는 쯔쯔가무시증은 제3급 법정감염병으로 관리되고 있으며, 설치류에 기생한 털진드기 유충에 의해 주로 매개되는 것으로 알려져 있다. 원인균인 O. tsutsugamushi 는 Gilliam, Karp, Kato와 같은 표준 혈청형 외에도 유행하는 국가에 따라 30종 이상의 다양한 혈청형이 존재하는 것으로 알려져 있어, 각 지역에 대한 지속적인 조사가 필요하다. 우리 연구진은 야생 설치류에 기생하는 털진드기의 O. tsutsugamushi 감염 여부를 확인하기 위해 충남 예산에서 2018년부터 2023년까지 3-4월, 10-11월에 걸쳐 수행하였 다. 총 142마리의 설치류가 포획되었으며, Hanging method로 설치류에서 분리된 털진드기는 총 18,347마리였다. 수거된 털진드기의 샘플 중 1/2은 질병관리청으로 이관하였으며, 나머지 절반을 이용하여 O. tsutsugamushi 감염 여부를 확인한 결과 2018년 5건, 2019년 2건, 2020년 0건, 2021년 9건, 2022년 0건, 2023년 36건이 확인되었으며, 혈청형 분석 결과 Je-cheon 28건, Young-worl 3건, Boryoung 9건, Koto Akita 1건, Gilliam 2건, Karp 9건으로 확인되었 다. 이번 연구를 통해 예산 지역 내 다양한 O. tsutsugamushi 혈청형이 있음을 확인하였으며, 이러한 결과는 향후 지역에 따른 혈청형 차이가 반영된 공중보건학적 전략 수립을 위한 기초자료로 활용될 수 있을 것으로 사료된다.
