Targeting 0 patients with adult peridntitis, the subgingival plaque was cllected in teeth, respectively, fr #16, #36, #44. A bacillus was cultivated by painting it ver the slid selective media f F. nucleatum and A. actinmycetemcmitans. Bacterial species were detected in 0 tth with 1 pieces, respectively. Thrugh single and multiplex, the psitive reactin was indicated in 43 teeth with 45 pieces, respectively, as fr F. nucleatum, and in 1 tth with 4 pieces, respectively, as fr A. actinmycetemcmitans. In the cmparative analysis between bacterial identificatin methds, F. nucleatum shwed the mre statistically significant difference(p = 0.000) in cmparisn between single and multiplex. Even A. actinmycetemcmitans was indicated significantly(p = 0.067) in a case that is based n 0.1 in significant level in the cmparisn between single and multiplex. In cnclusin, as a result f cmparing the bacterial identificatin methds, the detectin frequency was indicated t be higher in than in bacterial culture methd. and multiplex shwed the mutually similar detectin frequency. Accrdingly, given thinking f ecnmic efficiency, quickness, and reductin in labr frce, it is thught t be mre efficient methd t use single as the bacterial identificatin methd.,fz XPSET Fusbacterium nucleatum, Actinbacillus actinmycetemcmitans, methd, Multiplex, 서 론 e y e w, e, e e w y, e ³ w x» ³ w. ü 700 ³ wš 1), e e w e ³ ü Prphyrmnas gingivalis, Prevtella intermedia, Fusbacterium nucleatum, Campylbacter rectus, Trepnema denticla, Actinbacillus actinmycetemcmitans Bacterides frsythus ³ ¾ š ).

Kim 등 은 16S rrna 유전자(rDNA) 염기서열을 바탕 으로 F. nucleatum과 A. actinmycetemcmitans를 동시에 동정할 수 있는 multiplex 프라이머를 개발하여, 특 이성 및 민감도 조사를 실시하여 우수성을 보고하였고, 성인성 치주염 환자의 치은연하 치면세균막 샘플를 이용 해 multiplex 법과 single 법을 비교하였다. 본 연구는 Kim 등 의 연구를 바탕으로 성인성 치주염 의 치은연하 치면세균막에서 F. nucleatum과 A. actinmycetemcmitans의 동정을 위한 세균배양법, single 법 및 multiplex 법을 비교하여 효율적인 세균 8) 9-1) 13-15) 10) 10) 동정법을 알아보고자 실시하였다. 재료 및 방법 1. 치면세균막 채취 C 대학교 치과병원에 내원한 0명의 성인성 치주염[판 정기준: pcket depth 4 mm, bleeding n prbing] 환자를 대상으로 각각 #16, #36, #44 치아의 치은연하 치 면세균막을 멸균된 paper pint를 이용하여 채취한 뒤 1 PBS 500 µl에 담아 다음의 실험에 사용하였다.. 세균 배양 각각의 부위에서 채취한 샘플은 즉시 실험실로 옮겨 혐 기성 세균배양기 안에서 원액 50 µl를 1 PBS로 10,000배 희석한 다음 멸균된 면봉을 이용하여 F. nucleatum에 대 한 고형 선택배지(1% trytic sy brth, 0.5% yeast extract, 0.5% NaCl, 0.% glucse, 0.0% L-tryptphan, 1.5% Bact agar, 5% defibrinized sheep bld, 4 µg/ml erythrmycin, 5 µg/ml crystal vilet)와 A. actinmycetemcmitans에 대한 고형 선택배지[tryptic sy brth(tsb; Difc, USA); 0.6% yeast extract, 5% hrse serum, 1.5% Bact agar, 75 µg/ml bacitracin, 5 µg/ml vancmycin]에 각각 도말하였다. 37 C 혐기성배양기(85% N, 5% CO, Fig. 1.
