Abstract

Bacillus species are aerobic, gram-positive, spore forming rods, and they are usually found in the surrounding environment. If they are isolated in the clinical specimen, they are generally considered as contaminants rather than a true pathogen. Infection with Bacillus licheniformis is usually associated with the immunocompromised state, trauma, an indwelling intravenous catheter or an intravenous drug abuser. This infection is easily controlled by removal of the catheter and surgical debridement of the local infected tissue as well as an appropriate antimicrobial therapy. We reported here on a case of Bacillus licheniformis bacteremia associated with a bronchoscopic procedure in an immune competent patient.

Bacillus종은 그람양성 간균으로 포자를 형성하며 주변 환경 어디에나 존재하여 임상 가검물에서 분리되는 경우 대부분 오염균으로 생각된다. B. licheniformis에 의한 감염증인 경우 외상, 면역저하, 주사약물남용과 연관성을 가지며, 적절한 항생제 사용과 카테타 제거나 수술적 국소조직 제거에 의해 잘 치유되는 특징이 있다. 그러나 위험인자가 없는 상태에서도 B. licheniformis 균혈증은 생길 수 있으며 본 증례에서도 58세의 위험인자가 없던 여자에서 기관지경 후에 B. licheniformis 균혈증이 발생하였고 다른 증례들처럼 경험적 항생제 치료 후에 합병증 없이 치유되었다.
