초록
Arthrobacter 균종은 coryneform 그람양성간균이며 토양에 주로 서식하며 사람에서 상재균으로도 존재한다. Coryneform균이 치명적인 감염원이라는 보고가 증가하고 있으며 특히Arthrobacter에 의한 인체 감염이 최근 보고되고 있어 생화학적 검사 외의 추가검사를 통한 속, 종까지의 규명이 중요하다. 이에 저자들은 상품화된 동정키트인 API Coryne (bioMérieux, Marcy l'Etoile, France)에서 L. aquatica로 잘못 동정되었으나 16S rRNA sequencing으로 A. woluwensis로 동정된 균혈증 1예를 경험하였기에 보고하는 바이다.
Abstract
Arthrobacter spp. are coryneform bacteria known as a soil flora and also part of normal flora of human. Since coryneform bacteria are often reported to be a cause of life-threatening diseases, and especially the human infections of Arthrobacter spp. are reported recently, it is important to identify them to the genus and species levels by additional studies including molecular tests. We report a case of bacteremia caused by Arthrobacter woluwensis, which was misidentified initially as Leifsonia aquatica by commercial kits and conventional tests, but correctly identified by 16S rRNA sequencing.
