털진드기 발생감시를 위해 논, 밭, 수로, 초지 4지점에 채집기를 설치하여 조사하였다. 전체 채집 개체수는 7종 207마리가 채집되었다. 9월 5째주에 2마리를 시작으로 11월 3째주에 49마리로 가장 많이 채집되었다. 전체 채집 기간 중 지역별로는 초지, 수로, 논, 밭에서 각각 81, 52, 47, 27마리 채집된 털진드기를 표본 제작하여 동정한 결과 광릉털진드기(N. kwangneun) 73마리(35.3%)로 가장 많이 분리되었고, 수염털진드기(L. palpale)가 46마리(22.2%), 둥근혀털진드기(N. tamiyai)가 41마리(19.8%), 작은새방울털진드기(N. asakawai) 27마리(13.0%) 순으로 동정되었다. 야생설치류 44마리를 포획한 결과 등줄쥐(Apodemus agrarius) 35마리(79.5%), 땃쥐류(Crocidura spp.) 5마리(11.4%), 대륙밭쥐(Craseomys regulus) 2마리(4.5%)와 그동안 발견되지 않았던 흰넓적다리붉은쥐(Apodemus peninsulae) 2마리(4.5%)였다. 설치류에서 채집한 털진드기는 총 6,628마리 채집되어 chigger index는 150.6이었다. 시기별 chigger index는 10월에 234.2로 가장 높았고, 11월에 223.3, 4월에 75.6, 5월에 66.2 순으로 나타났다. 털진드기 검체로부터 쯔쯔가무시 병원체 PCR 검사는 모두 음성이었다.

Abstract ▼ AI-Helper

In order to monitor the occurrence of chigger mites, collectors were installed at four places: rice field, field, waterway, and grass field. Totally, 207 chigger mites belonging to 7 species were collected. Starting with 2 mites in the 5 weeks of September, a maximum of 49 mites were collected during 3 weeks of November. Totally, 81, 52, 47 and 27 mites were collected from grass field, waterways, rice field, and field, respectively. Analysis of sampling and collecting chigger mites determined that the most encountered species was Neotrombicula kwangneun (73, 35.3%), followed by Leptotrombidium palpale (46, 22.2%), N. tamiyai (41, 19.8%) and N. asakawai (27, 13.0%). The grab results of 44 wild rodents revealed Apodemus agrarius (35, 79.5%), Crocidura spp. (5, 11.4%), Craseomys regulus (2, 4.5%), and A. peninsulae (2, 4.5%; which had not been detected previously). A total of 6,628 chigger mites were collected from rodents, and the chigger index was determined to be 150.6. Chigger index was found to be highest at 234.2 in October, followed by 223.3 in November, 75.6 in April, and 66.2 in May. PCR from all chigger mite samples tested negative for the Tsutsugamushi pathogen.

용어 설명: PCR은 세균 특이성이 있는 primer를 이용하여 적은 수의 세균이 있을지라도 쉽게 검출할 수 있는 유용한 방법이며, 이를 이용하여 구강 내 치면세균막이나 타액에서 직접 세균을 검출할 수 있게 되었다[8].
