Five hundred five blood samples for culture were processed in the Isolator lysis-centrifugation system and were then inoculated into a Mycobacteria Growth Indicator Tube (MGIT) and onto a Lowenstein-Jensen (L-J) slant. Forty-nine isolates of Mycobacterium avium complex and three isolates of Mycobacterium tuberculosis were recovered from 50 of the blood culture specimens. Forty-five isolates from 43 specimens were recovered in the MGIT, with a mean time to detection of 21 days. Forty-one isolates from 40 specimens were recovered in the L-J slants, and the mean time to detection was 36 days. Nine specimens were positive in the MGIT alone, while seven specimens were positive only in L-J medium.
505份用于培养的血样在隔离器裂解离心系统中进行处理,然后接种到分枝杆菌生长指示管(MGIT)和罗-琴(L-J)斜面上。从50份血培养标本中分离出49株鸟分枝杆菌复合群和3株结核分枝杆菌。43份标本中的45株分离菌在MGIT中培养成功,平均检测时间为21天。40份标本中的41株分离菌在L-J斜面上培养成功,平均检测时间为36天。9份标本仅在MGIT中呈阳性,而7份标本仅在L-J培养基中呈阳性。
