Isolation of Mycobacterium Fortuitum from BACTEC 9240 Blood Culture System: A Case Report
自BACTEC 9240血液培養系統分離出Mycobacterium Fortuitum-案例報告
摘要
我們描述一位89歲的男性病人因爲肺炎住院治療，病歷記錄由Mycobacterium fortuitum (M. fortuitum)引起的菌血症。於住院期間做了兩套血液培養且呈現陽性結果。革蘭氏染色見到不典型陽性桿菌，推測可能是分枝桿菌，操作抗酸菌染色並呈現陽性結果。經過分枝桿菌培養鑑定出M. fortuitum。此案例的血液培養分離出M. fortuitum，不僅是因爲此菌屬於快速生長分枝桿菌，也由於俱經驗醫檢師的判斷及專業。醫檢師如遇到不典型革蘭氏陽性病原菌且培養需時較長的個案，應考慮操作分枝桿菌培養。

We describe an 89-year-old male patient who admitted due to pneumonia documented bacteremia by isolating Mycobacterium fortuitum (M. fortuitum) from BACTEC 9240 blood culture system in April 2009. During his admission, two sets of blood culture were reported as positive. Microscopic examination revealed atypical gram-positive bacilli and acid-fast organism. This organism was subsequently identified as M. fortuitum. Concerning that M. fortuitum could be cultured and isolated in this case, not only owing to it is a rapidly growing mycobacteria, but also the professionalism that the experienced technicians have. Laboratory staff should have awareness of performing mycobacteria culture when encountering an atypical gram-positive pathogen accompanying with delayed aerobic culture result.
